Abstract
Abstract IMPROVED CATALYSTS FOR THE SELECTIVE CONVERSION OF STRAIGHT-CHAIN HYDROCARBONS CONTAINED IN A HYDROCARBON FEED COMPRISE A CRYSTALLINE ALUMINO-SILICATE ZEOLITE OF THE ERIONITE VARIETY HAVING A LOW POTASSIUM CONTENT. PREFERABLY, THE LOW-POTASSIUM ERIONITE IS COMBINED WITH A METALLIC HYDROGENATION COMPONENT AND USED IN THE SELECTIVE CONVERSION OF LOW OCTANE-PRODUCING NORMAL PARAFFINS TO UPGRADE THE HYDROCARBON FEEDSTOCK. THE PROCESS IS PREFERABLY CONDUCTED IN THE PRESENCE OF ADDED HYDROGEN AT ELEVATED TEMPERATURES AND PRESSURES.
