In 1984, Chevron pioneered the all-hydroprocessing route for making high-purity
Group II and Group III base oils - base oils that are as clear as water.
Chevron introduced modern hydrocracking technology, the first step in hydroprocessing,
in 1959. Today, Chevron Lummus Global is the world's leading developer and licensor of hydroprocessing technology.
In 1993, Chevron introduced the ISODEWAXING® catalyst, which is now the industry
standard for meeting complex new specifications.
The ISODEWAXING® catalyst reshapes wax molecules into high-quality base oil molecules
rather than breaking them down into by-products as is done in conventional catalytic
dewaxing. The result is a chemically pure, clear, high-VI, low-pour-point base oil with
outstanding performance characteristics.
Today, most Group II and group III base oils worldwide are made using Chevron Lummus Global technology.
