Feeds. Properties of two hydrofined test feeds are given in Table I. The California gas oil blend was used in tests simulating a hydrocracking unit producing both naphthas and jet fuel, the Mid-Continent blend in tests representing a unit producing naphtha as the major product. 

In 1961, hydrocracking was introduced to convert gas oil into naphthene-rich heavy naphtha, which is a superb feed for a catalytic reformer. The first unit used the Isocracking process developed by Standard Oil of California (now Chevron Texaco).
