The effect of shale moisture content on [t.sub.vc] (air-dry basis and dry basis) is shown in Fig. 7. The operating conditions are A and E. Because the heating rate in fluidized bed is high, one can assume that the evolution of moisture takes place immediately once the oil shale is fed into the bed [13].
