摘要
Abstract
Thermo-gravimetric analysis was employed to study gasification kinetics of three coal direct liquefaction extract residue chars under steam and CO2 atmosphere. Gasification kinetics of liquefaction residue char was compared at the same conditions. It is shown that temperature plays a significant role on residue char gasification. The decreasing degree of order for carbon and increasing pore structure in residue chars due to supercritical solvent extraction improve gasification reactivity of residue chars. Due to the lack of pore structure, the experimental results of residue chars during steam gasification and CO2 gasification can be well described by the chemical reaction control shrinking core model.关键词
