Abstract: Midbarrel fuels boiling primarily between about 300* and about 700*F are selectively produced from higher boiling feeds containing less than 10 ppm nitrogen by hydrocracking in the presence of controlled amounts of added nitrogen compounds including ammonia or hydrocarbon amines in amounts corresponding to about 5 to about 100 ppm nitrogen. Furthermore, the relative distribution of midbarrel and lower boiling products can be controlled by controlling the amount of nitrogen compounds added to the hydrocracking zone.

Abstract: LIGHT GASOLINE FRACTIONS RICH IN N-HEXANE AND OPTIONALLY N-PENTANE, AND WHICH ALSO CONTAIN SMALL AMOUNTS OF BENZENE, ARE FIRST SUBJECTED TO HYDROGENTATION IN CONTACT WITH CERTAIN ZEOLITE-BASED PLATINUM-GROUP METAL CATALYST TO EFFECT SATURATION OF THE BENZENE CONTENT, AND TOTAL EFFLUENT FROM THE HYDROGENATION ZONE IS THEM SUBJECTED TO ISOMERIZATION IN CONTACT WITH A PLATINUM GROUP METAL SUPPORTED ON AN ALUMINA-CONTAINING BASE TO EFFECT ISOMERIZATION OF NORMAL PARAFFINS TO ISO-PARAFFINS. THE ISOMERIZATION CATALYST IS MAINTAINED IN AN ACTIVE STATE BY MAINTAINED A SMALL PROPORTION OF HYDROGEN CHLORIDE IN THE RECYCLE GAS.
