The deactivation of a nickel reforming catalyst during the upograding of the producer gas obtained by gasification of lignocellulosic biomass was studeied. The informations obtained allowed to elucidate the catalyst deactivation mechanism taking place during the reforming of the producer gas: physical deactivation by deposition of fine ashes, aerosol particulate or carbon; poisoning by H2S and HCl present in the gas phase and thermal sintering because of the high operation temperatures required to avoid the chemical deactivation. These physical and chemical effects depended on the composition of biomass fuel.
