The process is based on the Winkler gasifier which was developed by Fritz Winkler in the 1920 s. It should be noted that this was the first commercial fluidized bed process. The differences of the HTW process to the Winkler process are a higher pressure, higher temperature and a post gasification zone (PGZ).

The Winkler process for the gasification of coal has been in successful commercial operation since the middle 1920s. In the fluid bed of the gasifier coal reacts with a mixture of air or oxygen and steam. The gas leaving the gasifier is only a mixture of H2, CO, CO2, N2, and CH4. The basic process is discussed along with the heat and material balances and the advantages of the Winkler system.
