Abstract
An improved process for producing low pour point, high VI synthetic oils from feedstocks containing wax and residual olefinic unsaturation, said feedstocks having been obtained by thermal, non-catalytic polymerization of linear, C.sub.6 -C.sub.20 carbon atom monoalpha-olefins. The improvement comprises simultaneously hydrogenating and catalytically dewaxing the feedstock by contacting said feedstock and hydrogen with a hydrogen form mordenite catalyst at elevated temperature and pressure, thereby producing a stable synthetic oil of high viscosity index and low pour point.
