Technology Introduction
Hydrogen Production from Coal Gas

The institute’s hydrogen production from coal gas technique has matured; the process involves six procedures: gas generation, compression, desulphurization, conversion, PSA gas separation, and water circulation; the gas generation control and PSA gas separation systems are among China’s best and have won many Ministry of Chemical Industry and State Scientific and Technological Commission awards.

It has five hydrogen-production from coal gas installations either under construction or completed, and can handle 1500/3000/5000/10000 Nm3/h, or larger, hydrogen production from coal gas projects.
