Fischer-Tropsch process allows to obtain high quality lubricant bases and clean fuels from natural gas. In this goal, the n-paraffins produced have to be upgraded through a hydroconversion step aiming the isomerization of chains. In order to better understand the mechanisms involved, different bifunctional catalysts have been studied for the hydroconversion of n-hexadecane on a lab-scale trickle bed reactor. These catalysts are : a benchmark Pt/EMT, two commercial catalysts (Pt-Pd/SiO2-Al2O3), tungstated zirconias, as well as a new class of mordénite-based micro/mesoporous composite catalyst. A specific study highlighted the effects of mechanical treatments on activity and selectivity of tungstated zirconias. Relations between physico-chemical characterizations of the catalysts and their activities and selectivities for the hydroconversion of n-hexadecane were established

The present work is focused on developing an original micro to mesoscale approach to investigate various phenomena and then to intensify the performance of a reactor. At mesoscale, the emphasis is given to the interactions between granular sludge particles as well as the biogas production efficiency in a 2D reactor under various hydrodynamic conditions at different concentrations of substrate. Then, within the microdevices, a single sludge particle of various sizes was used under different operating conditions such as superficial liquid velocity and concentration of substrate. The effect of different hydrodynamic conditions and concentration of substrate was studied

Within the environmental contexts of power generation and waste disposal, the present works deals with the validation and the optimisation of a multistage thermo chemical process of particleboard waste conversion (enhancement). These wastes are mostly associated with urea formaldehyde and melamine formaldehyde resins which contain a huge amount of nitrogen. Nitrogen causes the production of pollutants such as ammonia, isocyanic acid, cyanhydric acid and NOx… during classical thermo chemical process (combustion, pyrolysis and gasification). The process studied aims in a first time to remove nitrogen species from waste to produce a combustible solid and in a second time to convert this residual solid in a combustible gas. The first step consists in a low temperature pyrolysis (250°C to 400°C) during 3 to 15 minutes and assumes to eliminate 70 % of the initial nitrogen content for all studied conditions. The pyrolysis and/or the pyrolysis / gasification under water of the residue are then studied between 800°C and 1000°C. The higher temperature of reaction (1000°C) improves the production of gases and the energy efficiency of this second step and allow the production of hydrogen and carbon monoxide rich gases. The pyrolysis / gasification under water allows a total conversion of the solid which optimises the energy efficiency of the process. However, the pyrolysis under nitrogen produces a lower amount of gases but helps to catch a part of the nitrogen in the residual char. The char then produced is converted through an activation step, in an active char containing nitrogen functionalities with high adsorption capacities, especially for the trapping of phenol or other aromatic compounds in liquid phase. This multistage is thus a interesting way to enhance low cost raw matter like particleboard waste

The objective of this work was to offer an ecological and economical process for the treatment of a complex mixture of hydrophobic and hydrophilic Volatile Organic Compounds (VOC), emitted by a hazardous waste collection company (Chimirec, Javené). The coupling of VOC absorption in waste oils, available on the industrial site, and its biological regeneration in a multiphasic bioreactor (« Two-Phase Partitioning Bioreactor ») was studied. The steps of the process were optimized at laboratory-scale and then on a pilot-scale installation on the industrial site. Among the waste oils available as organic phase for VOC absorption, lubricant and transformer oil were selected on the basis of scientific and commercial criteria. Transformer oil showed similar absorption performances compared to silicone oil, taken as reference, while lubricant was too viscous to ensure a satisfactory VOC removal. Nevertheless, batch experiments showed that biological regeneration is not compatible with waste oils. Indeed, waste oils being degraded before VOC in the two-phase bioreactor, these latter could not be satisfactory removed. However, experiments showed that thermal regeneration of waste oils by distillation at high temperature may be an interesting approach. Experiments were then led at pilot-scale with silicone oil, known as being not biodegradable. Satisfactory and constant performances of the process were observed during several weeks

Zhang, Xin. "Procédé hydrométallurgique pour la valorisation du nickel contenu dans les plantes hyperaccumulatrices." Thesis, Université de Lorraine, 2014. http://www.theses.fr/2014LORR0172/document.
Some plants, known as hyperaccumulators, are able to develop on metal containing soils and to accumulate these metals at high concentrations in shoots. Biomass incineration leads to ash containing 10 to 25 wt % nickels, greater than in some mineral ores. This work follows a research that has been carried out by the team for several years, which has resulted in a patent on the hydrometallurgical production of the double salt ammonium and nickel hexahydrate (ANSH) from the biomass of Alyssum murale. It aims at improving the synthesis method of this salt in order to upscale it at the pilot scale and explore new methods leading to new products. The manuscript begins with a bibliographic review on phytomining from hyperaccumulators to metal recycling processes, essentially focused on nickel. Then ca 15 hyperaccumulator plants (genus Alyssum, Leptoplax and Bornmuellera) collected in Greece or Albania have been compared, in the objective of phytomining. Nickel concentrations were measured in the plant organs and in the ashes after combustion. The three types of plants are of great interest for the technology, they contain 1 to 3 wt % of nickel and the ashes 15 to 20%. The hydrometallurgical process of ANSH production was investigated step by step to optimize each step to produce a salt of high purity, to decrease materials and energy consumption and to minimize effluent and waste production. The process was thus improved. Eventually, new ideas have been tested for new processes and nickel products. The obtained results and the current dynamics prove the interest of phytomining and announce its imminent development

According to the European Tyre Recycling Association (ETRA), more than 3 millions tonnes of waste tires are to be treated in Europe each year and are subject to legislation and regulation policies for the re-use and recycling of 95 % of the total mass of end-of-life vehicles. Despite the various opportunities for recycling used tires (civil engineering applications, material recovery, energy recovery), a part of the French available resource remains unvalued and none of the applications just mentioned focuses specifically on the recovery of carbon black, which is one of the main component of a tire. This high added value product is mainly used as reinforcing filler in the rubber and plastics industries. There are two types of industrialized thermal processes for recovering the carbon black from an end-of-life tire : pyrolysis and steam thermolysis. Steam thermolysis, currently industrialized by Alpha Recyclage Franche Comté (ARFC), is an efficient pyrolysis alternative which uses superheated steam at atmospheric pressure. The substitution of carbon blacks produced from a conventional manufacturing process by carbon blacks recovered from the steam thermolysis treatment is based upon the quality of the recycled product, especially regarding its physicochemical properties (intrinsic and surface). The objective of this work is to propose and implement an adequate methodology to recover and characterize the physicochemical properties of recovered carbon black (rCB) from steam thermolysis of a tire, to assess the impact of the process operating conditions on the properties of the rCB, and finally to valorize the rCB as an alternative reinforcing filler for the elaboration of a final product
