Investigations have been carried out on the effects of temperature, particle size, steam/coal ratio, and coal quality on the gasification of coal samples procured from two different mines in the Singrauli coal fields, India. A stainless steel reactor of 10 cm diameter and 100 cm length was used. Steam superheated to approximately 200°C was used as the reactant and fluidizing medium. The energy of activation was 5.17 and 2.25 kcal/mol for coals A and B, respectively. The CO/CO2ratio chosen as the index of gasification was found to decrease with an increase in steam/coal ratio. The ratio CO/CO2was independent of particle size and increased with an increase in temperature. The CO/CO2ratio was higher for coal A, having 36.7% ash.
