催化气化工业化进程展望

PROSPECT OF CATALYTIC GASIFICATION TECHNOLOGY IN INDUSTRIALIZATION PROCESSING

评述了分别以生产合成天然气甲烷(美国Exxson加压流化床)、中热值煤气(加拿大UBC加压喷动流化床和韩国KAIST常压导流管内循环流化床)、工业燃料气(中国福州大学常压"气化-煅烧"集成流化床)为目标的四种不同类型催化气化PDU实验结果及工艺过程的对比,指出应尽快建立燃煤自供热的流化床催化气化PDU装置,为实际工程放大设计提供有效信息.鉴于工业燃料气和合成气的广阔市场需求,优先开展"催化气化-灰渣煅烧"CGAC集成工艺专利技术研发,可望推进催化气化的实际工业化进程.

The experimental results of PDU and the technologic characteristics of four types of catalytic gasification process,with the purpose of respectively producing the synthetic natural gas-methane by pressuried fluidized gasifier at the Exxon of USA,the medium heating value fuel gas by pressuried spouted fluidized gasifier at the UBC of Canada,and by internaly circulating fluidized gasifier with draft tube at KAIST of Korea,the industrial fuel gas by the ＂Catalytic Gasification and Ash-cinder Calcination＂ integration system （i.e.CGAC） at the Fuzhou University of China,were reiewed and compared.It is clear that in order to provide more effictive information on the scaled-up engineering design the new PDU of catalytic fluidized gasifier providing heat with burning of coal itself needs to be establised urgently and special experiments in this PDU requires quickly in processing.Since the great demand in the market of industrial fuel and synthetic gases,preferentially developing the CGAC integration patent will make more progress in an actual industrialization processing of catalytic gasification technology.
