Phillips process

Chemistry

A process for making high-density polyethene by polymerizing ethene at high pressure (30 atmospheres) and 150°C. The catalyst is chromium(III) oxide supported on silica and alumina. This process was made commercially viable by Phillips Petroleum Corporation in 1961.

Chemical Engineering

1. A liquid-phase catalytic process used for polymerizing linear olefins (alkenes) such as ethylene into linear thermoplastic polymers such as high density polyethylene. It uses a Phillips catalyst, which is based on a chromium (VI) oxide on silica. Compare ziegler-natta catalyst.

2. A fractional crystallization process used for freeze-concentrating beer and fruit juices.

3. A two-stage process used for the dehydrogenation of butane to form butadiene.
