Discussion on producing synthesis gas by using high-sulphur soft coal instead of heavy oil
The gasification technologies of Texaco,Shell and CFB process are compared.The choosing of flow chart and pressure of Texaco gasification process are analyzed,and the carbon monoxide conversion,sulphide removing,CO 2 removing and refinement technologies for Texaco coal gas are described.The suggested process is gasification at 4 0MPa by Texaco quenching process,carbon monoxide conversion by sulphur resisting conversion catalyst,CO 2 and sulphide removing by NHD method,and refinement by low temperature conversion plus methanization.The processes for producing ammonia,hydrogen and methanol by using high sulphur soft coal as raw material are recommended.
