The Mobil-Badger Cumene process developed jointly with Raytheon Engineers and Constructors uses a highly selective proprietary ExxonMobil zeolite, MCM-22. This zeolite is exceptionally Selective for the alkylation of benzene wit propylene over other zeolites allowing it to be used at benzene-to-propylene ratios below 3 : 1 molar. The use of MCM-22 benefits the cumene Producer by allowing Production of high-Purity cumene at high yields，as Well as providing large increases in plant capacity and improved utility consumption. The first commercial operation of the new technology began in May 1996 and currently operated plants supply approximately half of worldwide cumene demand.
