摘要：In this paper, the physical-chemical properties of a Biomass Gasification Ash (BGA) and a Coal Gasification Ash (CGA) were investigated, and the effects of BGA and CGA on the CO2 gasification reactivity of petroleum coke was studied. Results show that the unburned carbon content of BGA is 8.82%, which is much higher than that of CGA, and the biomass gasification efficiency in the up-draft gasifier can reach 95.42%. The K content in BGA is much higher than that of CGA, and some catalytic components were contained in BGA, while no catalytic components were present in CGA. BGA and CGA can promote the gasification of petroleum coke to a certain extent depending on the ratio of BGA and CGA. The catalytic activity of BGA is superior to that of CGA, and the gasification reactivity of petroleum coke at the loading content of 30% CGA and BGA are about 1.4-and 5.5-fold higher than that of petroleum coke gasification alone. ? 2015 Taylor & Francis Group, London.
