Abstract
Abstract Processing different hydrocarbon raw materials into high-octane gasolines over zeolite-containing catalysts with pentasil structure has been studied in the absence of hydrogen in dependence on the technological parameters of the process. Correlations have been found between the hydrocarbon composition of the feed and the yield of gasoline and its composition. The possibility of increasing the octane numbers of light petroleum naphtha and gas condensate from 56–60 to 85–90 MON without hydrogen application has been shown. For low-octane number raw material, upgrading the catalyst IC-30 without previous hydropurification of the feed results in a decrease of the total sulfur content in synthesised gasolines to 0.1 wt% and simultaneous improvement in their antidetonate parameters. The non-hydrogen transformation of light petrol fractions of oils and gas condensates over IC-30 catalysts to increase the octane number and to reduce the sulphur content was performed on a pilot and industrial scale over three years.
