© Hydrogen production from biomass gasification is potentially a competitive, more environmentally friendly route to replace steam reforming of natural gas. In this study, waste wood and CO2 were used for hydrogen production via gasification. Using CO2, greenhouse gas, as an oxidizing agent enhanced the pyrolysis-derived char reactivity 6-7 times and reduced up to 35% the phenolic derivatives in the volatiles compared to the N2 pyrolysis environment, therefore enhancing the heterogeneous gas-solid reactions and reducing the formation of tar in the producer gas. The producer gas contained up to 78 mol % H2 and with low 10 mol % CO2 when combining CO2 and stream with up to 97% process efficiency compared to 67 mol % H2, 15 mol % CO2, and less than 90% process efficiency in N2/steam gasification. A significant reduction (97%) in the amount of tar and naphthalene constituents (58%), the main component in tar in the gas stream, was observed when Ni-based red mud (a waste product of bauxite processing) was added as a catalyst in the process.
