Testo completoAs global energy needs will continue to be met by fossil-fuel based sources, a viable solution to reduce CO2 emissions would be to implement carbon capture technologies. CO2 capture by absorption in amine solvents ranks among the most advanced technologies to be implemented on post combustion units. Still, its application is remains constrained large point sources with small sources remaining difficult to decarbonize. Recently, microwave heating has gained in popularity due to its characteristics of selectiveness, volumetric nature, and ease of control; on the other hand, membrane contactors are promising gas-liquid contactors due to their compacity, operational flexibility, and ease scalability in comparison to packed columns. In this work we explore the operation of chemical desorption when a hollow fiber membrane contactor by microwave heating.A comprehensive understanding of the interactions of microwave fields and transfer phenomena is essential for the correct design, operation, and optimization of an industrial scale equipment. Hence CO2 desorption rates were experimentally studied at the local scale of a single millimetric fiber, placed in a mono-mode microwave cavity. Numerical modeling of the fiber allowed the visualization of the temperature gradients formed inside the solvent, and the corresponding local desorption rates. In parallel, a prototype-scale unit was designed for the desorption of CO2 at the scale of a hollow fiber module under microwave fields. To this end we designed a custom-design cavity was made to house a membrane module in such a manner that CO2 desorption would take place simultaneously with electromagnetic heating

The objective of this study was to investigate the regeneration of activated carbon by microwave heating process. The multi-component adsorption of both benzene and toluene by spherical activated carbon (SAC) was tested in the research. The regeneration efficiencies of SAC under different experimental parameters included different types of carrier gases (air and nitrogen), carrier flow rates (2.0-10.0 l/min), microwave output power (350-700 W), and regeneration times (0-5 mins). The compositions of flue gas during regeneration were also identified and quantified in the investigation. Experimental results indicated that the decrease in regeneration efficiencies for SAC was detected in the experimental conditions of lower carrier gas flow rates, higher microwave output power, and air as carrier gas. The experimental results were also showed that the SAC pore size was increased and specific surface area was decreased after heating with microwave, which also resulted in the regeneration efficiencies less than 100%. The identified compositions in the flue gas included benzene, toluene, CH4, CO, and CO2. Both benzene and toluene were two major reaction products among these compounds, and the rest compounds mainly resulted from the decomposition of benzene or toluene and oxidation of carbon. The carbon balance for the investigation can be reached up to 90%. Higher concentrations of CH4, CO, and CO2 were observed in the experimental conditions of higher oxygen content in the carrier gas, lower carrier gas flow rates, and greater provided microwave energy. This research provided an innovative process for carbon regeneration.

Activated carbons (AC) have been used widely in the water and wastewater treatment and water reclamation plant. Since the benefit/cost of AC has been considered, the regeneration of AC has played an important role both in the treatment process and the cost reducing. Comparing to traditional regeneration methods, the advantages of microwave radiation process include shorter regeneration time, better efficiency, lower cost, less carbon loss, lower energy consumption, and without secondary pollution and specificity of the adsorbate. The objectives of this study were to regenerate the waste AC, which have been regenerated twice, sampled from water purification plant in Kinmen. The microwave radiation process was used as the regeneration method. Physical and chemical characteristics of regenerated AC were investigated. The diffraction intensity of regenerated AC was determined by XRD, structure changes were observed by SEM, and the specific surface area was analyzed by BET. The adsorption efficiencies of waste and regenerated AC under different operation parameters, such as radiation power, adsorption time, and temperature were investigated by iodine number. The iodine number of waste AC in Kinmen is approximately 450mg/gAC. With 20 mins radiation and power of 100 to 750W, the iodine number of regeneration GAC can all reach more than 800mg/gAC and the regeneration PAC can all reach more than 1050mg/gAC with 10 mins radiation and power of 450W.The iodine number will decrease with power higher than 850W resulted from carbon structure ruined. With using microwave radiation, not only the adsorption efficiency of regeneration AC is two times better than that of original waste AC, but also reducing the AC costs in Kinmenwater purification plant. Therefore, the microwave radiation process hasgreat potential for regeneration of waste AC.

In this study, a denudation wastewater from CD plate recycling process was diluted in concentrations of 100 mg-COD/L as adsorbate during a continuous isotherm adsorption of the activated carbon column. Then, thermal regeneration of the saturated activated carbons was carried out under a microwave-induced heating process. The adsorption capacity of the virgin carbon made of bituminous coal (B-AC) was measured ca. 0.5-2.2% lower than that of the virgin carbon made of coconut shell (C-AC). It may be due to various functional groups and amounts are on structures of them. The adsorption capacity of either B-AC or C-AC was also increasing with an increasing concentration of the adsorbate via batch equilibrium adsorption tests. This implies that a multi-layers adsorption may be occurred between the adsorbate and surfaces of the activated carbons. Freundlish coefficients of K and n were calculated to be 10.0786 and 2.8563 with C-AC as well as to be 13.0377 and 3.4916 with B-AC. The adsorption capacities of the regenerated fixed-bed with either B-AC or C-AC increased with an increase of output power of microwave (PMW), gas hourly space velocity (GHSV) of carrier gas, and heating time period (tMW). The regeneration efficiency of the C-AC fixed-bed was calculated highly up to 111.53% and 114.45%, respectively, as a result of the microwave-induced regeneration process was prolonged to either 15 or 18 min. Both the adsorbate and other substances previously adsorbed onto either C-AC or B-AC may be almost desorbed during the microwave regeneration runs. The regenerated fixed-bed of either B-AC or C-AC was found with a higher adsorption capacity than that of the ones filled either virgin B-AC or virgin C-AC. In addition, adsorption capacity of both the regenerated fixed-beds would reach a maximum value at the sixth adsorption/regeneration cycle, and then decreased approximately to a constant value. This means that the field-spent carbon regenerated by microwave-induced heating method can be reused more times than the ones after traditional thermal regeneration runs. The advantage of microwave-induced heating technology is not only can significantly reduce operation time during the regeneration of activated carbon process, but also can save cost of buying virgin carbon and disposal of spent carbon. The optimum conditions for the carbon fixed-bed regeneration process were found for 15 min under microwave energy at a power level of 427.8 W as well as the inert gas at a GHSV of 287.9 h1. Time period for the microwave-induced regeneration of either C-AC or B-AC fixed-bed is recommended for 25 min if water of the carbons is removed by the gravity only. The energy cost of the microwave-induced regeneration runs is calculated approximately 7% of the regeneration runs carried out by heating with a traditional electrical furnace. Furthermore, cost of carrier gas consumed for the microwave-induced regeneration runs is about 30% of the electrical furnace heating runs.

The increasing levels of highly concentrated ammonium nitrogen wastewater in different bodies of water can cause serious ecological damage. Despite the abundance of techniques in treating ammonium nitrogen in water, there is still a lack of method that can be used to rapidly convert it. In this study, synthetic zeolite was utilized to adsorb high concentration of ammonium nitrogen in a simulated solution, and then the zeolite was regenerated via a rapid, dry plasma chemical process in order to convert and remove the ammonium nitrogen. The removal of NH4+-N from water was conducted using 5~20 g-zeolite/L-wastewater, 5-1000 mg-NH4+-N/L of NH4+-N, adsorption time of 0.25-48 hour, and operated at 25℃. The effect of ammonium nitrogen adsorption capacity (mg NH4+-N/g zeolite) and the NH4+-N removal rate (%) were studied. The regeneration of zeolite was then carried out at 1200 W and 200-400℃ for 2 min using nitrogen or air microwave plasma torch. The comparisons of zeolite after regeneration by different methods such as plasma, NaCl solution, and thermal treatment, was also performed in this study. The results from the analyses (crystal structure and morphology) made indicated that the synthetic zeolite is mainly composed of X-type zeolite and a trace of type A zeolite. Based on the conducted experiment, the maximum adsorption capacity could reach up to 41.4 mg NH4+-N/g zeolite and it can reach saturation within 15 minutes. This indicates that the zeolite has a high and rapid adsorption to ammonium nitrogen. Moreover, the ammonium nitrogen desorption rate can reach up to 80% when it was desorbed with 2 M NaCl solution. The study also revealed that at the given parameter: 25℃, initial NH4+-N concentration of 1000 mg-NH4+-N/L, and adsorption time of 15 min, the removal efficiency of NH4+-N reached 60% with an adsorption capacity of 29.8 mg NH4+-N/g-zeolite. The regeneration of zeolite was done using air plasma at 1200 W and 400℃. However, at 400℃, the desorption rate of NH4+-N reached up to 94% but the structure and morphology of zeolite were damaged, which resulted to a difficulty in repeated adsorption. Upon the comparison of plasma and thermal regeneration at 300°C, it is found out that the generated amount of air plasma regeneration and desorption is 79.2% of the theoretical adsorption capacity, which leads to an increased application efficiency. When the plasma is operated below 300℃, the specific surface area and destruction efficiency of NH4+-N have minimal influence in the decrease of adsorption capacity of the regenerated zeolite. However, it was detected that the zeolite retained its original crystal structure and morphology. In conclusion, the regeneration and reuse of synthesized zeolite for adsorbing ammonia -N in wastewater and desorption by dry plasma process, is a promising technique in the treatment of industrial wastewater.
