Coal is the most important energy source in China. The utilization of coal should consider not only the efficiency but also the reduction of pollutants and CO₂ emission. Compared with coal utilization by conventional combustion, the route to different products via coal gasification is recognized as the most advanced technological concept for clean coal use. The products from coal gasification cover the whole product spectra currently obtained from oil. This paper summarizes recent progress made in the Institute of Coal Chemistry, Chinese Academy of Sciences in the field of coal gasification, mainly in the gasification using an ash agglomerating fluidized bed gasifier together with the gas cleanup challenges, Fischer-Tropsch synthesis with an iron-based catalyst and a slurry bed reactor, higher alcohol synthesis, and the one-step dimethyl ether synthesis from coal-based syngas.
