Abstract
A hydrocarbon fraction, preferably in the kerosene boiling range containing a substantial proportion of C.sub.9 + hydrocarbons is contacted with an n-paraffin fraction, such as n-pentane, over a catalyst of acidic functionality, such as Pd/zeolite beta, under conditions of hydrocracking sufficient to convert the feed to lower boiling range materials of high octane number. The n-paraffin cofeed promotes isomerization and suppresses production of n-paraffins.
Claims15
A process for upgrading a hydrocarbon fraction which begins to boil at about 285.degree. F. (140.degree. C.) and contains a significant proportion of C.sub.9 hydrocarbons, comprising the steps of;
- a) feeding the hydrocarbon fraction and a lower n-paraffin feed fraction to a hydrocracking reaction zone;
- and
- b) hydrocracking the feeds in the hydrocracking reaction zone of step a) over a catalyst of acidic functionality in the presence of hydrogen, under conditions of elevated temperature and pressure to convert the feed to a product comprising a hydrocarbon fraction having a larger proportion of hydrocarbons boiling in the gasoline boiling range and a lower proportion of n-paraffins than the feed.
