Abstract: A PROCESS FOR HYDROGENATING BENZENE IN THE VAPOR PHASE WITH MOLECULAR HYDROGEN IN A REACTION ZNE IN THE PRESENCE OF DILUENT CYCLOHEXANE VAPOR AND A HYDROGENATION CATALYST WHEREIN A PORTION OF THE HEAT OF REACTION IS ABSORBED FROM THE REACTION ZONE BY INDIRECT HEAT TRANSFER MEANS INTO A CIRCULATING LIQUID STREAM COMPRISING CYCLOHEXANE AND BENZENE AND WHEREIN SUCH HEATED CIRCULATING LIQUID STREAM IS CONTACTED WITH A MOLECULAR HYDROGEN CONTAINING GAS TO FORM A VAPORIZED REACTION CHARGE MIXTURE COMPRISING BENZENE, HYDROGEN AND DILUENT CYCLOHEXANE. REACTION ZONE TEMPERATURES ARE MAINTAINED WITHIN A DESIRABLE OPERATING RANGE BY ABSORBING HEAT FROM THE REACTION ZONE INTO THE CIRCULATING LIQUID STREAM AND SUCH ABSORBED HEAT IS SUBSEQUENTIALLY UTILIZED TO VAPORIZE THE BENZENE AND CYCLOHEXANE COMPONENTS OF THE REACTION CHARGE MIXTURE AND TO PREHEAT THE REACTION CHARGE MIXTURE TO THE DESIRED REACTION INLET TEMPERATURE.

Abstract: Clusters of petroleum coke pellets are made by the steps of dispersing particulate carbon seed particles in a high boiling petroleum oil, heating the seeded oil in a coking heater under conditions of controlled cracking, and introducing the effluent from the heater into a coke drum where the seed particles serve as nucleating agents in the formation of clusters of petroleum coke pellets.
