Multi-stage conversion fluidized bed coal gasification technology combines the advantages of the existing pressurized ash agglomerating fluidized bed(AFB) coal gasification process and circulating fluid bed(CFB) coal gasification process. Integrating pyrolysis, gasification, and combustion as a whole, the MFB coal gasification technology produces methane-rich syngas, with a methane content of 5~8%. 

 

With the sponsorship of CAS and the First Heavy Machinery Group Corporation, a pilot plant with the capacity of 100 tons coal/day at 3.0MPa has been set up and put into operation. A single demonstration plant is expected to process 1,000 to 2,000 tons of low rank coal per day and produce 100~150 million cubic meters of synthetic natural gas yearly.
