英文摘要Catalytic steam hydrogasification of coal is a direct method for methane production. Calcium looping concept is usually used in coal gasification process for in-situ carbon dioxide removal and heat supply. In this paper, a new process combining catalytic steam hydrogasification and calcium looping was proposed and investigated using a self designed instantaneously feeding reactor under high-temperature and pressurized conditions. The effects of operation conditions (including hydrogen concentration with a range of 0-50 vol%, gasification pressure with a range of 0.1-3.5 MPa, gasification temperature with a range of 700-800 degrees C, and gasification-calcination cycle number up to six) on the performance of the new process have been studied. The results show that: (i) increasing H-2 concentration is beneficial to methane products; (ii) high temperature and low pressure are not conducive to methane production and carbon dioxide capture as well as the self-sustained heat supply in gasifier; (iii) the methane content and carbon conversion can be maintained at 30-40 vol% and 75-80% for the durability tests. According to the performance of gas products, 750 degrees C 3.5 MPa and Ca/C = 0.5 are suggested for the new process. In addition, the gasification reactivity can be affected by the Ca-K-Char interaction as indicated by the XRD, FTIR and SEM-EDX analysis.
