Steam gasification of cellulose powder has been studied, using a sponge-like porous Ni catalyst. The reactor with the catalyst was heated through an electric heater. The powder was quickly put on the catalyst surface kept at 800℃. The influence of the Ni catalyst poisoned by steam and the steam/carbon ratio (S/C) on product gas yield was analyzed. The most striking result is that carbon yield of the product gasses was almost constant for more than S/C ratio of 2.5 while hydrogen and oxygen yields increase with S/C.
