Five domestic gasification technologies in China were presented and reviewed, including opposed multi-burner (OMB) gasification technology of coal water slurry (CWS), oxygen staged gasification technology, two-stage dry feed entrained flow gasification, pulverized coal gasification process of HT-L, and ash agglomerating fluidized bed gasification. The former four technologies belong to pressurized entrained flow gasification technology. The process description, technology characteristics, research and development process, performance indexes and commercialization progress of these technologies were mainly discussed.
