摘　　要：燃煤排放的CO2是温室效应的最大贡献者,煤基能源系统也就成为实现CO2零排放的重点研究对象.分析了国内外零排放煤基能源系统的研究进展,归纳了目前煤基能源系统实现CO2零排放的三种途径:基于IGCC系统的开拓研究,包括燃烧后分离与回收、燃烧前合成煤气处理与分离以及以IGCC为基础的煤基动力化工多联产系统;CO2接受体气化法为基础的煤基能源系统和化学链式煤气化煤基能源系统.Greenhouse effect mostly results from CO2 emission by coal combustion, so coal-based energy system is the main fields to realize near zero emissions. The international situa- tion of coal-based energy systems with near zero emissions currently was analyzed, and concluded that there are three approaches to realize CO2 near zero emission of coal-based energy systems： exploit study of IGCC, including recovery and separation after combustion, disposal and recovery of synthesis gas before combustion, and coal-based poly-generation system for power and chemi- cal products based on IGCC; coal-based energy system based on CO2 acceptor gasification and that on chemical-looping gasification.
