Streszczenie:
AbstractDisilylacetylene (1) has been obtained from LiAlH4 reduction of bis(trichlorosilyl)acetylene (2) and bis[(trifluoromethylsulfonyloxy)silyl]acetylene (4). The catalytic hydrosilylation of 2 with HSiCl3 affords tris(trichlorosilyl)ethene (5) and 1.1.2-tris(trichlorosilyl)ethane (6). The synthesis of 6, trans-bis(trichlorosilyl)ethene (8) and 1,1-bis(trichlorosilyl)ethene (9) has been accomplished by hydrosilyiation of trichlorosilylacetylene (7) which was synthesized by the reaction of trichloro(trifluoromethylsulfonyloxy)silane with sodium acetylide. Reductive elimination of halogen from 1,1,1,2-tetrachloro-bis(trichlorosilyl)ethane (10) and 1,2- dibromo-1,1-bis(trichlorosiIyl)ethane (13) gave the corresponding ethenes 1,1-dichloro-bis- (trichlorosilyl)ethene (11), trichloro-trichlorosilylethene (12), 1,1-bis(trichlorosilyl)ethene (9) and 1-chloro-2,2-bis(trichlorosilyl)ethene (14). Tetrakis(trichlorosilyl)ethene (15) has been obtained in a three step synthesis starting from chloromethyl-trichlorosilane or dichloro- methyl-trichlorosilane. By LiAlH4 reduction of trichlorosilylethenes under various reaction conditions, the silylethenes trans-dichloro-di(silyl)ethene (16), 1,1-dichloro-di(silyl)ethene (17), trichloro-silylethene (18), 1-bromo-l-silylethene (19), trans-di(silyl)ethene (20), 1-chloro-2,2-di(silyl)ethene (21), tri(silyl)ethene (22) and 1,1,2-tri(silyl)ethane (23) could be generated. Silylethyne and silyl-chloroethyne were identified as side products. The crystal and molecular structures of 2,5 and 15 have been determined by single crystal X-ray diffraction. 2 and 5 crystallize from the melt in the monoclinic space groups Cc and P21/n, respectively. 15 has been crystallized by sublimation (orthorhombic. space group Pbca). 5 and 15 feature strongly distorted ethene skeletons with a double bond twist of 28.1° in 15.

Streszczenie:
The biological production of ethanol from ethane for the utilization of ethane in natural gas was investigated under ambient conditions using whole-cell methanotrophs possessing methane monooxygenase. Several independent variables including ethane concentration and biocatalyst amounts, among other factors, were optimized for the enhancement of ethane-to-ethanol bioconversion. We obtained 0.4 g/L/h of volumetric productivity and 0.52 g/L of maximum titer in optimum batch reaction conditions. In this study, we demonstrate that the biological gas-to-liquid conversion of ethane to ethanol has potent technical feasibility as a new application of ethane gas.

For the first time, volatile hydrocarbons were measured in Croatia, at Mali Lošinj in the period from autumn 2004 to autumn 2005. Mali Lošinj site is conveniently located as a gateway to Croatia for any potential pollution from either Po valley in Italy, or other locations in southern Europe or even Africa. The sampling was performed on multisorbent tubes and then analyzed by thermal desorption gas chromatography with a flame ionization detector. The aim was to determine and estimate the non-methane hydrocarbons in Mali Lošinj, a location with Mediterranean vegetation and species which emit large quantities of volatile organic compounds. Ozone volume fraction and meteorological parameters were also continuously measured, from April to October 2005. Ethane, ethene, ethyne, propane, propene, n-pentane, n-hexane, benzene and toluene were identified in all air samples. Benzene and toluene have been found in ambient air and significant positive correlations between ethyne and ethane, propane and propene indicate emissions from transport.

Thermolyses of N,N,N′,N′-tetramethylethylenediamine (1a), N,N,N′,N′-tetraethylethylenediamine (1b) and sym-N,N′-dimethylethylenediamine (1c) at 760–825 °C have been studied by ultraviolet photoelectron spectroscopy. Although the corresponding N-alkylated aminomethylene radicals were not observed, this study establishes that thermolysis of 1a is an efficient route to N-methylenimine (3a); methane, ethane, and ethene are the other major products. Diamine 1b yields, besides ethane, ethene, and propane, heretofore unreported N-ethylmethylenimine (3b). Diamine 1c yields imine 3a and methylenimine (3c), as well as hydrogen, methane, ethane, and ethene. Molecular orbital eigenvalues of the imines are calculated using HAM/3, MNDO, HF/STO-3G, HF/3-21G, and HF/6-31G* methods.

Khan, Asad Ahmad. "Oxidative dehydrogenation (ODH) of ethane to ethene over supported vanadium containing oxide catalysts". Thesis, Cardiff University, 2016. http://orca.cf.ac.uk/91544/.

Pełny tekst źródła
Streszczenie:
In this thesis work oxidative dehydrogenation (ODH) of ethane to ethane over MoV oxide catalyst was investigated. The influence of the preparation techniques and different reaction conditions were studied thoroughly. It was found that the precipitation method for the catalyst preparation using variable pH produces a more active catalyst at pH values of 3 to 3.5. Slurry temperature and calcination temperature are also very important parameters which affect the selectivity pattern of the products. This selectivity pattern was found to be further influenced by reaction temperature, pressure, GHSV and ethane-oxygen ratio in the feed. The influence of the V: Mo ratio on the performance of the catalyst for the ODH was investigated by several characterisation techniques, such as BET, XRD, XPS, TEM, SEM, EDX coupled with catalytic performance tests in a fixed bed reactor. The optimum V: Mo ratio was found to be 0.25:1 (i.e., MoV0.40). At this ratio, the oxidation state of vanadium with respect to total vanadium concentration (V5+/Vtotal) is at an optimum in terms of the adsorption strength of the desired products. It was further fine-tuned by investigating the influence of reaction conditions. An improvement on the most active MoV oxide catalyst for the ODH reaction was developed with the addition of oxalic acid as the vanadium dissolution and pH adjustment agent. Addition of oxalic acid influenced the catalytic properties in a variety of ways as observed from characterisation and reaction results. Addition of either a smaller amount or an excess amount compared with the optimal amount has determental impact on the activity of the catalyst. Further catalytic activities were tested by the addition of different types of supports (e.g., ZrO2, TiO2, Nb2O5, SiO2, and AlO3) into the MoV oxide catalytic system. The alumina support was extensively tested with different amounts onto the base MoV oxide for the ethane ODH to ethane.

Streszczenie:
In this research, oxidative dehydrogenation of ethane to ethylene was studied over Cr-O and Cr-V-O mixed oxide catalysts through steady-state and dynamic experiments. The catalysts were prepared by the complexation method. By XRD, presence of Cr2O3 phase in Cr-O
and the small Cr2O3 and V2O4 phases of Cr-V-O were revealed. In H2-TPR, both catalysts showed reduction behaviour. From XPS the likely presence of Cr+6 on fresh Cr-O was found. On Cr-V-O, the possible reduction of V+5 and Cr+6 forms of the fresh sample to V+4, V+3 and Cr+3 states by TPR was discovered through XPS. With an O2/C2H6 feed ratio of 0.17, Cr-O exhibited the highest total conversion value of about 0.20 at 447°
C with an ethylene selectivity of 0.82. Maximum ethylene selectivity with Cr-O was obtained as 0.91 at 250°
C. An ethylene selectivity of 0.93 was reached with the Cr-V-O at 400°
C. In the experiments performed by using CO2 as the mild oxidant, a yield value of 0.15 was achieved at 449°
C on Cr-O catalyst. In dynamic experiments performed over Cr-O, with C2H6 pulses injected into O2-He flow, the possible occurrence of two reaction sites for the formation of CO2 and H2O was detected. By Gaussian fits to H2O curves, the presence of at least three production ways was thought to be probable. Different from Cr-O, no CO2 formation was observed on Cr-V-O during pulsing C2H6 to O2-He flow. In the runs performed by O2 pulses into C2H6-He flow over Cr-V-O, formation of CO rather than C2H4 was favored.

Streszczenie:
The environmental occurrence and behaviour of the brominated flame retardant (BFR) decabromodiphenyl ethane (dbdpe) has only been studied to a limited extent. It is structurally similar to decabromodiphenyl ether (decaBDE), which makes it conceivable that dbdpe may also become an environmental contaminant of concern. A method for environmental analysis and comparative assessments of dbdpe and decaBDE was developed. Both BFRs were studied in: a mass balance of the Henriksdal WWTP in Stockholm (Paper I); an international survey of sewage sludge (Paper II); sediment along a transect from Henriksdal WWTP to the outer archipelago of Stockholm and from isolated Swedish lakes (Paper III); and a benthic food web from the Scheldt estuary (Paper IV). Dbdpe was found in sludge from every country surveyed, indicating that it may be a worldwide concern. The WWTP mass balance showed that virtually all of the BFRs were transferred from wastewater to sludge. A small fraction was emitted via the effluent, confirming emissions to the aquatic environment. In the marine sediment, the BFR levels close to the WWTP outfall were high. They decreased along the transect to low levels in the outer archipelago. The study of lake sediment showed a widespread presence of dbdpe in the Swedish environment and provided evidence that it originates from long range atmospheric transport. In the food web, dbdpe did bioaccumulate to a small extent which was similar to decaBDE. The transfer of the BFRs from sediment to benthic invertebrates was low, while transfer from prey to predator was higher. Biodilution was observed rather than biomagnification. This work suggests that the persistence, the susceptibility to long range atmospheric transport, and the potential for bioaccumulation are similar for dbdpe and the regulated decaBDE that it is replacing. Thus, there is a risk that a problematic environmental pollutant is being replaced with a chemical that is equally problematic.
At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Submitted. Paper 4: Manuscript.

Streszczenie:
Abstract Supercritical water gasification of dilute ethanol at the industrial scale promises a sustainable route to bio-syngas production for use in combined cycle power plants. Cost-effective bio-syngas production would reduce reliance on fossil fuels for electricity generation and reduce greenhouse gas emissions by utilizing waste biomass resources. Continuous supercritical water gasification offers high reactant conversion at short residence times without an added catalyst. The decomposition of ethanol in supercritical water is studied in a continuous reactor at 560 °C, 25 MPa, residence times between 3 and 8 s, and a constant initial ethanol concentration of 8.1 wt%. High-resolution, in-situ Raman spectroscopy facilitates identification of reaction products. Significant yields of H2, CO, and CH4 indicate the dominance of a dehydrogenation reaction pathway at studied conditions, while minor yields of ethane indicate a secondary dehydration reaction pathway. Ethylene yields are virtually nonexistent, indicating rapid hydrogenation of ethylene to ethane at these conditions. Ethanol dehydrogenation to H2, CO, and CH4 results in an overall fuel value upgrade of 84.5 kJ/mol-EtOH. Dehydration of ethanol to ethane results in an overall fuel degradation of −3.8 kJ/mol-EtOH.

Reliance Industries Limited (RIL) planned to import liquid Ethane from North American market for use as feedstock in Gas Crackers at Dahej Manufacturing Division (DMD), Hazira Manufacturing Division (HMD) in the state of Gujarat and Nagothane Manufacturing Division (NMD) in the state of Maharashtra. Liquid Ethane was planned to be unloaded at GCPTCL (Gujarat Chemical Port Terminal Company Limited) Jetty and stored in cryogenic tank in DMD. For use in NMD and HMD, it was proposed to transport Ethane via a dedicated pipeline traversing through the states of Gujarat and Maharashtra and deliver at respective gas crackers of HMD and NMD in a direct usage mode as no storage facilities for Ethane were envisaged at delivery locations. Reliance Gas Pipelines Limited (RGPL), a wholly owned subsidiary of RIL implemented the Asia’s 1st liquid Ethane Pipeline project as “Dahej - Nagothane Ethane Pipeline Project” (DNEPL) and successfully commissioned the pipeline in September, 2018. This paper presents the Conceptual Design of the project including selection of phase of transportation, pipeline configuration in terms of pipeline size, no. of pump stations, spacing of main line valves (MLV’s), operating conditions, material of construction and emergency evacuation requirements of Ethane during long haul transportation.

Abstract This study investigated engine efficiency and emissions at low load dual-fuel diesel-natural gas (NG) engine operation, which has a higher sensitivity to NG composition. 40% of the diesel fuel energy was partially substituted with gas blends containing methane, ethane, and propane. NG was delivered inside the intake manifold by low-pressure gas injectors. Results showed that blends with ethane and propane reduced the net global warming potential by ∼5% compared to pure methane, at constant fuel energy content, with the reduction primarily linked to differences in exhaust hydrocarbon composition. No statistically significant impact on the brake mean effective pressure was found. The changes in gas composition created up to a 10% increase in carbon monoxide concentrations in the exhaust, as an earlier combustion phasing increased the fraction of premixed NG trapped in the combustion chamber’s crevices. Also, a 20% reduction in specific methane, ethane, and propane emissions was achieved for mixtures with 10% propane addition. Propane addition enhanced combustion efficiency and methane oxidation compared to ethane addition. The reduction of methane, ethane, and propane mass fraction in the exhaust correlated with their auto-ignition temperatures and laminar flame speeds, with ethane and propane oxidizing significantly better than methane. Finally, the results imply the emission composition of diesel-NG dual-fuel operation was more sensitive than engine power output to the change in NG fuel composition.

Abstract This study investigates combustion performance of a CO2 rich fuel mixture containing ethane and methane as active species using a constant volume combustion chamber. This fuel is obtained as a byproduct of a chemical looping based oxidative dehydrogenation (Cl-ODH) process ethylene production. The byproduct gas mixture has a CO2 concentration of 40.79%, 39.49% ethane, and 4.88% methane by weight with other minor compounds. Using the fuel for energy extraction would improve the process efficiency of the ethane to ethylene conversion. After initial combustion modelling, the gas fuel mixture was reduced to just the major species: CO2, ethane, and methane. The mixture was then tested for flammability limits and combustion performance under spark-ignition conditions. Effects of ambient conditions like temperatures between 300 to 400 K with initial pressures from 1 to 10 bar were tested. The effects of stoichiometry were tested to understand flame velocities and heat release. The fuel mixture showed an overall reduced flame velocity compared to gasoline. Instability in combustion was believed to be caused by the dissociation of ethane under elevated conditions. At higher pressures, the flame produces lower cumulative heat release. Data from this study was used to modify a small-scale spark-ignition engine to use this fuel and produce usable energy.

This report documents an investigation into the effects of high BTU (by volume) fuel gas on performance and emissions from a GMVH-6 two-stroke integral engine compressor operating with the OEM fuel-air curve control strategy. The high BTU fuel gas was blended to simulate imported LNG compositions with high ethane content. The testing was performed by blending pure ethane into typical pipeline natural gas to achieve ethane contents ranging from two to seventeen percent by mole. A laboratory GMVH-6 engine was tested with these various fuel blends in both pre-combustion chamber and open-chamber configurations. Three speed-load conditions were tested with the pre-combustion configuration and one additional speed-load condition was tested with the open-chamber configuration. For each configuration and operating condition, a constant NOX fuel-air curve was mapped and programmed into the engine controller. Ignition timing was set slightly retarded from optimal for each operating speed to provide margin against detonation with the high ethane content blends.
