Gas oils, California

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. 

Product Distributions. All of the tests with California gas oil were made at a recycle cut point of 550°F, arbitrarily chosen and not necessarily an optimum cut point for operation with any of the catalysts.

Therefore, we have two effects on isobutane/ n-butane ratio that tend to offset each other. The result, with the California gas oil, is that there is...

The trends are generally the same as those at the higher cut point with California gas oil. The catalyst with the higher ratio of hydrogenation activity to acidity, Catalyst C, produces more C5+ naphtha the more highly acidic catalyst, Catalyst G, yields product with a higher octane number. 

The Illinois H-Coal syncrude contains the greatest amount of iron. This iron could be from corrosion during processing or storage, rather than from the coal itself. We have observed high iron contents in California gas oils which contain acidic and corrosive oxygen. In California gas oils, the iron is soluble in the oil as iron naphthenates (iron salts of organic acids) ...
