✦ Synopsis
AbsWact-Activation of Latrobe Valley brown coal by reaction with steam was investigated in a continuous indirectly heated shaft activator. The variables studied were the degree of coal gasification achieved, the ratio of steam feed rate to coal feed rate and temperature of activation. The most important of these variables is the degree of gasification of the coal. The ratio of steam feed rate to solids feed rate is unimportant when the value of this variable is greater than 0.036 g/g, and temperature is unimportant in the range 720-930°C. Process limitations which can be caused by channelling of both gas and solids and by heat transfer limitations have been discussed briefly.
