Olefin conversion technology

Olefin Conversion Technology, also called the Phillips Triolefin Process, is the industrial process that interconverts

. The 2-butenes are then subjected to metathesis with ethylene.

Rhenium- and molybdenum-containing heterogeneous catalysis are used. Nowadays, only the reverse reaction is practiced, i.e., the conversion of ethylene and 2-butene to propylene:^[2]

CH₂=CH₂ + CH₃CH=CHCH₃ → 2 CH₂=CHCH₃

The technology is founded on an

supported on alumina.
