摘　　要：为了解目前国内气流床气化工艺的开发与应用现状,对国内正在使用的6种气流床气化工艺———Shell工艺、GSP工艺、两段式工艺、Texaco工艺、多喷嘴对置式工艺和多元料浆工艺进行了介绍,并对各工艺的特点进行了综合分析。根据对煤种和后续产品的适应性,并结合各工艺的特点,提出了工艺选择的基本原则:气化煤种为高灰分、高灰熔点煤或褐煤,优先选用GSP工艺,其次选用Shell工艺和两段式工艺;气化后煤气用于煤气化联合循环发电(IGCC),优先选用Texaco工艺,其次选用Shell和两段式工艺;气化后煤气用于合成氨或合成甲醇,优先选用多元料浆工艺和多喷嘴对置式工艺,其次选用GSP工艺和Texaco工艺。In order to understand the development and application status of the present domestic entrained flow bed coal gasification technique,the paper had a introduction on the present domestic applied six entrained flow bed gasification techniques,including the Shell technique,GSP technique,two stage technique,Texaco technique,multi burners technique and multi component slurry technique and had a comprehensive analysis on the features of each technique.According to the suitability of the coal type and the sequence products,in combination with the features of each technique,the paper provided the basic principle of the technique selected.The gasified coal shall be a high ash and high ash fusion coal or lignite.The GSP technique would be optimally selected and the Shell technique and the two stage technique could be selected.The gasified gas could be applied to the IGCC.The Texaco technique could be optimally selected and the Shell technique and the two stage technique.The gasified gas could be applied to the production of synthetic ammonia or synthetic methanol.The multi component slurry technique and multi burner technique could be optimally selected,then the GSP technique and the Texaco technique could be selected.
