Abstract

NiO/SBA-15 with nano NiO particles and cavities, has high catalytic ability for gas conversion and favors the decomposition of large tar molecules derived from gasification due to its larger pore sizes. Therefore, in this work the bench-scale cedar gasification was achieved using NiO/SBA-15 as a reforming catalyst to produce H2 rich producer gas. NiO/SBA-15 appeared to be suitable for H2 rich (over 50 v/v% (N2 free)) producer gas production, as well CH4, CnHm and tar reduction. Although the amount of NiO did not affect the gas composition, tar removal was decreased when the amount of NiO was considerably increased. In addition, the conversion of the producer gas was also carried 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% CO2 was converted to CO, whereas no CO2 conversion occurred in the presence of steam. At low temperatures, the maximum CH4 yield in the absence of steam was 23%, which was higher than that in the presence of steam (15%).
