Abstract:

The development of stable catalysts involving innovative materials and active phases other than noble metals (e.g., transition metals) is a contemporary issue for the industrialization of reforming reactions. This particularly concerns the reaction of methane with carbon dioxide (Dry Reforming of Methane, DRM) whose interest is to produce, from two widely available greenhouse gases (CH4 and CO2), a synthesis gas (SynGas, H2:CO=1:1) perfectly suitable for the subsequent production of higher and useful hydrocarbons (olefins, gasoline) by Fisher-Tropsch synthesis. The purpose of this work is the application of widely accessible ??green? inorganic solids in DRM for subsequent energy production. In this context, diatomite earths, submitted to different commercial treatments, were used as catalytic supports for the dispersion of 5 wt.% nickel using the two solvents method (cyclohexane/water). In spite of their low cost and wide availability, these natural porous solid powders were never tested before as supports for metallic species, in particular Ni, in DRM. Structural (by XRD), textural (by N2 sorption isotherms) and morphological (by SEM) properties of the supports as well as of the impregnated samples, will be presented. The dispersion was analyzed according to the origin of the diatomite powder. Catalytic performances of Ni/diatomites, after in situ pretreatment under H2, were compared to those obtained with a reference catalyst, prepared similarly, over an Aerosil 300 (no strutural porosity) silica support. A special attetion was paid on the type (regenarable, non-destructive and destructive) and amount of carbon species developped in the course of the reforming reaction.
