Hydrogen-cascade process for hydrocarbon conversion
Abstract
Abstract AN ECONOMICAL HYDROCARBON HYDROPROCESS OF MODIFIED HYDROGEN CIRCULATION WHICH EFFECTS SAVINGS IN COMPRESSION BY HYDROGEN CASCADE IN A PROCESS REQUIRING THE RECYCLING OF HYDROGEN. PARTICULARLY DIRECTED FOR UTILIZATION HYDROCRACKING, THE PRESENT PROCESS IS APPLICABLE T THE HYDROGENERATION OF AROMATIC NUCLEI, THE RING-OPENING O CYCLIC HYDROCARBONS FOR THE PRODUCTION OF JET FUEL COMPONENTS, DESULFURIZATION, DENTRIFICATION, HYDROGENATION, ETC. THE PROCESS INVOLVES SEPARATELY REACTING PORTIONS OF THE FRESH FEED CHARGE STOCK IN INDIVIDUAL REACTION SYSTEMS INTERCONNECTED BY WAY OF THE FLOW OF CIRCULATING HYDROGEN. A CATALYTIC PROCESS WHEREIN THE CATALYTICALLY ACTIVE METALLIC COMPONENTS ARE SELECTED FROM THE METALS OF GROUPS V-B, VI-B OR VIII.
