The approximate solution method for correcting for the effect of internally generated bulk flow developed in part 1 is applied to the gasification of oil shale char which involves a number of gas-solid reactions. The method was developed based on a rather simple gas-solid reaction system, but it is shown to work quite well for a complex system. A method for extending the application to an even more involved system is discussed. 15 references, 6 figures, 1 table.
