Review of coal gasification technology for synthetic ammonia and the selection of process scheme

This paper compares the coal gasification technology for synthetic ammonia using domestic coal as raw material,,and mainly discusses the coal quality requirements,the scope of coal,operating conditions,effective gas content,consumption and gasification efficiency,environmental impact and other aspects for oxygen rich continuous gasification in atmospheric fixed-bed,Ende furnace coal gasification,fluidized bed ash-melting powdered coal gasification,Texaco water gasification of coal slurry,Shell's dry pulverized coal power pressurized gasification,the domestic multi-nozzle coal water slurry gasification,the four-nozzles pressurized dry pulverized coal gasification and two-stage dry pulverized coal gasification and other pressurized gas technology.Combination of geographical location of Tianzhu Mountain Chemical Co.,Ltd.,coal,and other environmental conditions and economic factors,the oxygen-richcontinuous gasification in atmospheric fixed bed.was choosed as the technology of coal gasification for synthetic ammonia oxygen-richcontinuous gasification in atmospheric fixed bed.
