抄録

In recent years, biomass gasification technology has been attracting more and more attention as an environmentally friendly biomass conversion technology. Biomass char gasification is the most important step of the overall operation of biomass gasification. The char gasification reaction is the limiting step in the global gasification reaction and is of major importance in designing biomass gasifier. In this study, biomass char gasification experiments in H₂O, CO₂ and their mixtures were carried out in a batch type vertical tube furnace. The gasification characteristics and temperature dependence of biomass char in various gasifying agents were experimentally investigated. We also studied the mixed atmosphere gasification and found the char reactivity in a mixed atmosphere of steam and carbon dioxide can be expressed as the sum of the individual reactivity obtained in single atmosphere gasification experiments.
