Laboratory gasification of five Canadian coals

Results of a gasification study of five Canadian coals in a 100g laboratory fixed-bed gasifier are reported. The coals were three bituminous coals (Byron Creek, Prince and Devco) and two lignites (Coronach and Bienfait). When gasified in an equal mixture of nitrogen and oxygen at 850 °C, the lignites reacted more rapidly and produced more liquid and gaseous products than the bituminous coals, whereas the bituminous coals produced more methane but less carbon monoxide. Overall rates for both the gasification and combustion processes were 3.20, 2.80, 1.84, 1.70 and 1.25 wt% carbon conversion per min for Coronach, Bienfait, Prince, Byron Creek and Devco coals, respectively.
