  • Combination process for upgrading oil products of coal, shale oil and crude oil to produce jet fuels, diesel fuels and gasoline
    Patent number: 4409092
    Abstract: A combination process for upgrading hydrocarbon fractions obtained from raw shale oil, oil products of coal processing and select fractions of crude oils comprising sulfur, nitrogen and metal contaminants to produce jet fuel product fractions such as JP4, JP5, JP8 and other turbine-type fuel materials provided. The combination of integrated processing steps involving hydrotreating, acid extraction of basic nitrogen compounds and hydrofining thereof to produce a feed composition suitable for catalytic reforming in the absence of significant hydrocracking whereby jet fuel boiling range material is produced significantly reduces by the combination the hydrogen requirements of the process.
