MILLER, a citizen of the United States of America and resident of Emeryville, County of Contra Costa, State of California, have invented new and useful improvements in AN OCTANE UPGRADING PROCESS FOR LIGHT PARAFFINS USING A COMBINATION OF TWO PALLADIUM-ZEOLITE CATALYSTS The research octane of a light paraffinic hydrocarbon feed is effectively measured by consecutively contacting the feed under hydrocarbon conversion conditions with a palladium-HY-zeolite-alumina catalyst and then with a palladium-HZSM-5-zeolite-alumina catalyst.</p> |
