Abstract: The effective utilization of residue from direct coal liquefaction is important in both economic and environmental concern. Gasification behavior of Shenhua coal and the residues from the direct liquefaction of the Shenhua coal was investigated and compared using a fluidized bed reactor combined with gas chromatography (GC) analysis. The effect of remained and enriched mineral, catalyst and heavy oil on CO2 gasification of residue char was examined. The results show that the residue char has a better gasification activity than the raw coal char. The gasification reactivity index of the residue char is 0.135 and 0.290 at 1000℃ and 1100℃，respectively; but that of raw coal char is 0.118 and 0.20, respectively. The gasification reactivity of acid washed residue char (AR) is lower than that of acid washed coal char (AC), but the gasification reactivity of untreated residue char is greater than that of the raw coal char, which indicates that the remained and enriched mineral is a good catalyst for residue gasification. The Febased catalyst added during direct liquefaction also has a catalytic effect on the gasification process. Removal of heavy oil from the liquefaction residue leads to the decrease of the gasification reactivity of residue char.
