Regeneration of product ZnCl/sub 2/ catalyst melt from hydrocracking Colstrip coal with molten ZnCl/sub 2/ catalyst was demonstrated for the first time in a continuous 2 kg/h fluidized combustion regeneration unit. The regeneration process efficiently burned out the carbon, nitrogen, and sulphur impurities, efficiently removed the coal ash, and restored the catalyst to ZnCl/sub 2/. Recovery of zinc in the primary regeneration step was greater than 98.5%. With a secondary zinc recovery step, overall zinc recovery was 99.7%. It was demonstrated in a continuous bench-scale hydrocracker that the regenerated zinc chloride catalyst, after a single cycle of hydrocracking and regeneration, was fully as active as fresh ZnCl/sub 2/ catalyst.
