Cumene

The Versalis/Lummus Technology cumene process produces cumene by alkylation of benzene with propylene. It is based on Versalis’ proprietary zeolite catalyst PBE-1, which has been used in commercial operation since the late 1990s. PBE-1 has a higher selectivity to cumene than other common zeolite catalysts, and is equally effective for alkylation of benzene as well as the transalkylation of polyisopropylbenzenes to cumene. It is noncorrosive, regenerable and environmentally friendly.
