Dewitz, T S

This patent describes a process for the production of synthesis gas wherein coal is partially oxidized at an elevated temperature and pressure by feeding finely divided coal and oxygen to a gasification zone of a reactor, the ratio of coal to oxygen being such as to maintain a reducing atmosphere, and producing raw synthesis gas having a temperature of from about 2000{degrees} F. to 3000{degrees} F., the raw synthesis gas carrying with it a minor amount of at least one contaminating substance which is normally solid in form at room temperature, and partially cooling the synthesis gas sufficient to solidify the contaminating substance carried thereby.
