Abstract
To eliminate the tar coming from biomass pyrolysis, a kind of nickel-based monolithic catalyst is prepared in this study. The specific surface area, pore volume is characterized. The effect of different acid treatment time, different nickel loading quantity on its catalytic activity is investigated. The results show that the specific surface area is 156m2/g after acid treatment of 5h. The loading quantity of active component is linear with coating times. The influence of coating times on the gas composition is quite small, and the sum of the content of H2 and CO keeps as high as 90 vol %. After 6h catalytic reaction, the phase structure of catalyst hasn't any change, and the tar conversion decreased from 87.4 wt % to 81.3wt %. The quantity of the coking is tested to be about 1wt %.
