Hydrocracking is a flexible catalytic refining process that can upgrade a large variety of petroleum fractions. It is commonly applied to upgrade the heavier fractions obtained from the distillation of crude oils, including residue.

Hydrocracking converts heavy petroleum fractions into lighter products by breaking C−C bonds in the presence of hydrogen. It is in fact a collection of processes which transform a variety of feedstocks into both finished products and streams for further upgrading by downstream units.
Designing a hydrocracking process begins with defining key parameters such as feed rate, feedstock qualities, hydrogen availability, product yields and qualities, and catalyst cycle life.
Hydrocracking is a mature technology with established procedures for operation that are decades old. However, these procedures may not be perfect and may not apply exactly to every unit. Significant incidents have led to industry-wide changes, but these changes must be managed properly on a case-by-case basis.
Hydrocracking was introduced by Unocal (then known as Union Oil Co.) in collaboration with ESSO, with the process called “Unicracking-JHC” in 1960.
