Abstract

Gasification of coal-derived char by steam was carried out in a fluidized-bed reactor with a continuous feed and discharge of solids over a temperature range of 1096 to 1311K at atmospheric pressure. Calculation based on the bubbling bed model and kinetic information obtained by thermogravimetric analysis explained the experimentally obtained conversions of both outgoing steam and char.
