| Abstract: | The characteristics and key technologies of deep coal seam underground gasification (UCG) were analyzed, the demonstration field test was introduced, and the combination of UCG and carbon capture and storage (CCS) was studied. At last, the application of deep coal seam gasification in China in the future was prodicted. The results show that deep coal seam gasification through CRIP technology is feasible. Heat value of the product gas is similar to that from surface coal gasification and superior to that from shallow coal seam gasification. High pressure is favorable for gas composition and stable gasification. In addition, deep coal seam gasification can be combined with carbon storage to realize zero-emission fuel processing. |
