There is currently a strong need for new and effective energy recovery from renewable resources. In response to this, a gasification and gas conversion process has been developed in which producer gas is first catalytically reformed to a mixture of H2, CO, and CO2. This is followed by further catalytic conversion to CO and CH4 at different temperature ranges. Reforming was investigated by using the originally developed catalysts containing Ni at 750�C.In the further conversion process, we investigated the reverse water gas shift (RWGS) reaction at temperatures over 600�C and methanation at lower temperatures (350�400�C). Reforming as part of this further process was conducted by using novel mesoporous catalysts along with other effective metal components. The results showed that the H2 content exceeded 50 vol% over the NiO/SBA-15 catalyst under N2-free conditions. Catalyst obtained by a direct synthesis method was effective for the RWGS reaction, whereas a catalyst obtained by a post-synthesis method was suited to the methanation reaction. Maximum CO2 conversion reached 50% at 750�C using a 10% NiO/SBA-15 catalyst.
