Abstract
The catalyst is withdrawn from a coal hydroliquefaction reactor while it is maintained on stream by withdrawing a portion of the catalyst, in a separate stream, dispersed in product from the liquefaction zone, with such withdrawn stream being further diluted with liquid recovered from the main product stream to reduce the catalyst concentration. The catalyst containing stream is introduced into the ash separation zone, wherein catalyst is recovered with the ash containing solids. Fresh catalyst is subsequently added to the liquefaction zone in a stream of the liquid recovered from the main product stream.
