AbstractBiomass, as a neutral carbon source, is considered as an ideal primary energy source. Gasi?cation is an important process in regards to the utilizationof biomass in energy recycling, which convertsbiomass into a producer gas mixture consisting of CO, H2, CO2, and other trace species. As the producergas mixture has a low energy density, it is not very practical. To addressthisissue,a reforming process following gasification is also generally requiredto increase H2concentration and reduce impurities.And the producer gas is often reformed to produce useable CO3–5and synthetic natural gas (SNG)6–10.In this study we performed a detailed investigation on the bench-scale gasification of biomass to produce H2rich producer gas, or followed by chemical conversion of the producer gas using NiO/SBA-15 as a catalyst.  NiO/SBA-15 appeared to be suitable for H2rich (over 50 v/v% (N2free)) producer gas production, as well CH4,CnHmand tar reduction. Although the amount of NiO did not affect the gas composition, tar removalwas decreased when the amount of NiO was considerablyincreased. In addition, theconversion of the producer gas was alsocarried out at high and low temperatures in the presence or absence of steam, using NiO/SBA-15 as a gas conversion catalyst. Regardless of the conversion temperature, conversion of the producer gas was largely affected by steam. At 750°C and no steam ≈14% CO2was converted to CO, whereas no CO2conversion occurred in the presence of steam. At low temperature, the maximum CH4yield in the absence of steam was 23%, which was higher than in the presence of steam (15%).
