To achieve clean and efficient coal utilization, various gasification processes were modelled and simulated to obtain their energy potential degrees in this study. Effects of reaction conditions on the product composition, exergy efficiency, and energy potential change were evaluated. The energy potential matching degrees of coal gasification processes were compared. Results show that high temperature, low pressure, low oxygen coal ratio and high water coal ratio are beneficial to increasing the amount of effective gas, i.e., H2 and CO. Low oxygen and water coal ratio can enhance the exergy efficiency of coal gasification processes, because they can improve the output gas energy potential. The exergy efficiency of coal conventional gasification process peaks as the gasification temperature reaches 900℃. The exergy efficiency of coal chemical looping gasification process peaks as the gasification pressure reaches 1.5 MPa. The results may provide some guidance on the selection and optimization of process operation parameters.
