hydrocracking

[′hī·drō‚krak·iŋ]
(chemical engineering)
A catalytic, high-pressure petroleum refinery process that is flexible enough to produce either high-octane gasoline or aviation jet fuel; the two main reactions are the adding of hydrogen to petroleum-derived molecules too massive and complex for gasoline and then the cracking of them to the required fuels; the catalyst is an acidic solid and a hydrogenating metal component.

The company's VCC slurry phase hydrocracking technology is capable of processing a wide range of feedstocks and enables production of fuels that meet environmental specifications without further upgrading.
Within the liquid product, the higher percentages of C9 - C15 alkanes were achieved at the higher temperatures using fresh catalyst, indicating that an increase in reaction temperature favours hydrocracking. Furthermore, fresh catalyst proved to have a greater effect on the degree of hydrocracking when compared to its regenerated counterpart.
