The influence of the preparation conditions (impregnation and calcination temperatures, and calcium content) on the catalytic behaviour of Ni-CaO/olivine catalysts, prepared by wet impregnation method, in the elimination of non interesting by-products (CO2, CH4) produced from biomass gasification was studied. To select the preparation parameters and to understand their influence, several physicochemical analyses such as zetametry, DTA, XRD, TPR and SEM, were performed. The methane dry reforming and subsequently the modified dry reforming in presence of H2 and CO, reproducing the gas-effluent composition after air-wood gasification process, were carried out.
