Abstract: This study investigated the effects of various bed materials (silica, biomass-based activated carbon, coal-based activated carbon, and zeolite) used in the second-stage reactor and different gasification conditions on the H2 fraction in the syngas. The equivalence ratio was fixed at 0.3, and the temperature in the first-stage reactor was held constant at 500 °C. Three temperatures were tested in the second-stage reactor, and the steam/biomass ratio was also tested.
