Abstract
The gasification reactivity of Shenhua coal char (CC) and Shenhua coal direct liquefaction residue char (RC) with CO2 and steam was studied using a fixed bed reactor. The results show that CC has a higher steam gasification activity than RC, while RC has a higher CO2 gasification activity than CC, which is due to different influencing factors for steam and CO2 gasification. For steam gasification the reactivity of char is mainly affected by coal rank, but for CO2 gasification the reactivity of char is mainly affected by the catalysis of mineral matter.
