Abstract:

In this paper,the deactivation of the hydrogenation catalyst with reaction time is studied by hydrogenation of high temperature coal tar over the micro-fixed bed reactor.The regeneration effect of high temperature calcination method and solvent washing method is studied and analyzed,based on which a suitable method for catalyst regeneration is finalized.
