A bituminous and a sub‐bituminous coal from Western Canada have been gasified in oxygen‐steam and air‐steam mixtures in a 0.30‐m diameter, 50 kg coal/h continuous spouted bed reactor. Results are presented to show the effects of the blast composition and reactor temperature on gas heating value and carbon conversion. Operation in the ash agglomeration mode is illustrated, and the role of K 2 CO 3 as catalyst explored. Results from a wide range of experimental gasification conditions are compared with predictions of an equilibrium model.
