摘要
煤气化技术是发展煤基化学品、煤基液体燃料、联合循环发电、多联产系统、制氢、燃料电池等工业的关键技术,其中气流床气化具有易大规模化、煤种适应范围广、碳转化率高等特点,近年来得到规模应用。介绍以水煤浆为原料的GE Texaco(德士古)、Global E-Gas(原Destec)技术,以及国内开发的水煤浆气化技术和以干煤粉为原料的Shell、PRENFLO、Si-mens GSP技术及西安热工院有限公司的两段式气化技术。对这些技术的优缺点进行了对比。
Coal gassification is a key technology for developing coal-based industries, such as chemical products, liquid fuel, combined cycle power generation, multiple co -generation system, hydrogen production, and fuel cell etc.. The dry-fed gassification in an air flow bed has advantages of high throughput per gassifier, wide adaptibility of coal sorts, and high carbon conversion efficiency, so it is easily to be used in large- scale gassification. Moreover, the dry- fed coal gassification rechology, such as Shell, Prenflo, GSP and TPRI two - stage gassification, as well as slurry- fed technology, such as Texaco, E- Gas, and domestic developed coal gassification have been presented, and these two kinds of technology being compared.
