Refinery operators additionally have some ability to adjust the product mix from a barrel of oil with technologies such as catalytic cracking and reforming.

The Dubbs process was used extensively by many refineries until the early 1940s when catalytic cracking came into use.

Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions.

Although not naturally present in petroleum in high percentages, they can be produced from petrochemicals or by catalytic cracking of petroleum.

Fluid catalytic cracking (FCC) is one of the most important conversion processes used in petroleum refineries.

Hydrocracking is a catalytic cracking process assisted by the presence of an elevated partial pressure of hydrogen gas.

In the US, Fluid Catalytic Cracking is more common because the demand for gasoline is higher.

Designated HVU for CCF (cat cracker feed).

Fluid catalytic cracking is a commonly used process, and a modern oil refinery will typically include a cat cracker, particularly at refineries in the US, due to the high demand for gasoline.

Polybutene is typically made from cat cracker mixed C4s (after the stream is Merox treated to remove sulfur and amines, and contain 1-butene, 2-butene, and isobutylene.

Because the demand for gasoline, compared to other petroleum products, is much greater than the supply that naturally occurs from distillation, some of the heavier components are sent on to the catalytic cracking unit, commonly known as the cat cracker.
