✦ Synopsis

In order to develop a reaction simulator for purposes of direct coal liquefaction, a kinetic model for the initial stage of the reaction was developed for sub-bituminous Wandoan and Tanitoharum coals. The kinetic parameters in the model were determined by ®tting the model to experimental data obtained by autoclave tests. Based on the model, a simulator for a preheater was proposed. The yields of liquefaction products predicted by the simulator were veri®ed from data obtained at the outlet of the preheater in a process support unit with a capacity of 1 t of coal per day.
