In order to improve the comprehensive utilization efficiency of coal and natural gas resources in northern Shaanxi,optimize the composition of syngas,and couple the reaction heat,a pilot-scale study of coal and natural entrained flow co-gasification technology was carried out on the basis of the previous re-search.The construction scale and process flow of the coal and natural gas co-gasification pilot plant were introduced,and the long-term operation stability of the unit was investigated during the test,and the effects of gasification pressure,operating load and natural gas to coal ratio on the co-gasification reaction were explored.It is believed that under stable operating conditions,coal-natural gas co-gasification can re-duce raw material consumption and carbon dioxide emissions at the same time,which has certain technical advantages compared with traditional coal-water slurry gasification.
