摘要
简要介绍了固定床气化、流化床气化、气流床气化等主要煤气化工艺,对不同煤气化工艺的清洁生产及环境保护水平进行了对比分析,指出确定煤气化工艺时,在考虑煤种适应性和合成气用途的同时,还应兼顾建设地区资源、能源以及环境承载能力等因素,注重生产过程资源回收利用和污染物控制,在提高生产效率的同时,提高煤炭资源的利用率,以实现经济最优化和清洁生产。
It briefly describes some major coal gasification processes such as the fixed-bed gasification, fluidized- bed gasification, entrained flow gasification, etc., and comparatively analyzes clean production and environmental protection of different coal gasification processes. When determining a coal gasification process, besides the varieties of feed coals as well as the application of product gas, the regional resources, energy and environmental bearing capacity of the project construction site shall also be...
