Abstract
Abstract Certain hydrophobic derivatives of zeolite Y are found to be unusually selective and active catalysts with adequate stability for use in the conversion of high boiling petroleum feedstocks into fuel gases, gasoline and middle distillate products such as diesel and turbine fuel.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
151 words
In the method for selectively converting hydrocarbons boiling above about 700° F. to midbarrel fuel products boiling between about 300° and 700° F. which comprises reacting said hydrocarbons with hydrogen under hydrocracking conditions in the presence of a catalyst composition comprising a hydrogenation component and a crystalline aluminosilicate cracking component, the improvement which comprises utilizing as a cracking component a zeolite aluminosilicate having a SiO 2 /Al 2 O 3 molar ratio of from 4.5 to 35, the essential X-ray powder diffraction pattern of zeolite Y, an ion exchange capacity of not greater than 0.070, a unit cell dimension a.sub.° of from 24.20 to 24.45 A, a surface area of at least 350 m 2 /g (B-E-T), a sorptive capacity for water vapor at 25° C. and a p/p.sub.° value of 0.10 of less than 5.00 weight percent and a Residual Butanol Test value of not more than 0.40 weight percent.
