Abstract
This paper describes the effect of Zn on the gas production of a fluidized-bed gasifier to determine the relationship between Zn and the gasification process. Different concentrations of Zn were used in the preparation of artificial waste to elucidate the effect on gas product composition, gas product heat value, gas production rate, and H2 yield in the gasification process. Zn served to increase H2 generation during the gasification process. The molar percentage of H2 with more than 0.1 wt% additional Zn increased by 33.02% and the H2 yield was increased by 11.34% compared to that without Zn. However, the gas heat value decreased, and no significant change in the gas production rate was noted.
