Abstract. The Shell gasification process features a pressurised, slagging, entrainedflow reactor fed with dry, pulverised coal and oxygen. A 6 t/d pilot plant has been operating since 1976 in Amsterdam, and a 150 t/d plant has logged more than 6000 h at Harburg, West Germany. Both have used mainly European coals.
