Full textThe chemical activity of catalysts has long been the core of R&D studies, leading to an increased influence of internal diffusion limitations. It is therefore important to model and quantify these mass transfer limitations in order to optimize catalyst design and increase performance.In the framework of our project, 2D or 3D pore networks, constituted by interconnected cylindrical pores, are randomly generated by a Monte Carlo approach to reproduce the porosity, specific surface area and pore volume of gamma-alumina supports. A highly efficient tool, capable of generating 2D networks of 18000×18000 and 600×600×600 nodes in 3D, containing up to 2 billion pores. Only 4s are required to generate 2D networks of size 200x200.Mass transfer is simulated by the 1D Fick’s diffusion model within each pore of the network. 200×200 networks, containing up to 80,000 pores, can be simulated. The confrontation of the calculated tortuosities as a function of porosity, to theoretical correlations shows a good agreement. However, when comparing with experimental values from fixed-bed tracer experiments obtained for different gamma-alumina pellets, actual aluminas exhibit higher tortuosities, probably due to the organisation of the porous structure in two levels.Hence, by modifying the developed model to generate two-level networks, we have been able to reproduce both textural and diffusion properties of one alumina. Taking a 2D periodic network of size 100×100 and concerning the textural properties, relative errors less than 10% were obtained. In addition, a good agreement was found for the tortuosity values, 2.34 against the experimental value of 2.40

Full textThe aim of this study was to evaluate catalytic membrane reactor for wet oxidation efficiencies of pollutants in waste water. In a first part, we have prepared catalytic membrane using several techniques of deposition in order to well control the position of the active phase in the porous structure. After optimisation of the experimental parameters, the study of pollutant degradation has showed that catalytic membrane reactor, in contactor configuration present highest efficiency than conventional reactor due to optimized contacts between reactants and active sites

Full textA novel double membrane reactor was constructed and tested for continuous water and wastewater treatment by ozonation. The coupling of membrane separation and ozonation in the same reactor was found to significantly enhance the degradation of the selected model organic pollutant, while preventing fouling of the zeolite membrane. In parallel, an original ozonation method has been developed for removing the organic template from the zeolite membrane pores. This low temperature activation method results in higher quality membranes compared to traditional activation methods. Additionally, catalysts commonly reported in the literature to be active for ozonation were prepared and tested. The results demonstrated that gamma alumina and alumina supported catalysts do not have a real catalytic activity. The observed enhancement of organic removal during catalytic ozonation is mainly due to the contribution of adsorption and possibly to metal leaching from the catalyst
