Abstract: Modern coal gasification technology is an important part of modern coal chemical industrial plants,involving stable operation of the entire coal plant. This paper introduces application of modern coal gasification technologies in China,summarizes characteristics of gasification processes,application parameters,market data,etc. The first class gasification technology is entrained-bed gasification process,which can be divided into dry pulverized coal pressurized gasification and wet coal-water slurry pressurized gasification. The typical dry pulverized coal pressurized gasification technologies include Shell Gasifier,GSP Gasifier,HT-LZ Gasifier,WHG (Ning Mei) Gasifier,Two-stage Gasifier,CHOREN CCG Gasifier,SE Gasifier. The typical wet coal-water slurry pressurized gasification technologies include GE (Texaco) Gasifier,coal-water slurry gasifier with opposed multi-burners,Multi-component Slurry Gasifier,Non-slag/slag Gasifier (modified as Tsinghua Gasifier),E-gas (Destec) Gasifier. The second class gasification technology is fluidized-bed coal gasification process. The typical fluidized-bed coal gasification technologies include U-gas Gasifier,SES Lignite Gasifier,CAGG Gasifier. The third class gasification technology is fixed-bed coal gasification process. The typical fixed-bed coal gasification technologies include Lurgi Lignite Gasifier,Crushed coal Pressure Gasifier,BGL Gasifier. This paper points out the importance of coal gasification and recommends the strategic goal of combination of foreign advanced coal gasification concepts and modern coal gasification technologies with independent intellectual property rights.
