Chevron Research, development hydrocracking

Isocracking A hydrocracking process developed and licensed by Chevron Research Company. The catalyst is nickel or cobalt sulfide on an aluminosilicate. First commercialized in 1962 more than 45 units had been built by 1994. See also Isomax. 

Paragon A two-stage hydrocracking process, based on the zeolite ZSM-5, claimed to increase the yield and quality of the gasoline produced. Developed by Chevron Research Company, but not commercialized by 1991. 

Another development of the 1960 s was that of stable, large-pored catalysts which could crack very heavy feeds (37). For example, in Richmond, Chevron has had a hydrocracker processing deasphalted oil (DAO) since the middle 1960 s. The H-oil process was commercialized by Hydrocarbon Research, Inc., also in the 1960 s as a residuum hydrocracking process (38).
