Ethylbenzene alkylation (EBMax℠)
ExxonMobil’s zeolite catalysts are the heart of the Badger EBMax℠ process. Originally developed by Mobil Oil, the MCM-22 family of zeolite catalysts revolutionized the production of ethylbenzene (EB). With their high activity and selectivity to EB, ExxonMobil catalysts enable a simple, liquid phase process that dramatically lowers operating temperatures and thereby reduces equipment sizes and energy consumption – all while still improving the ethylbenzene product quality.
Today TechnipFMC Badger Process Technology and ExxonMobil continue to build upon a 35+ year relationship to deliver an optimized, cost-efficient, easy-to-operate technology to enable our customers’ success for the production of EB in the styrenics value chain.
A transalkylation reactor uses ExxonMobil catalyst to convert the small amount of PEB with benzene in the liquid phase. The effluent is sent to distillation to recover the additional EB production.
Ethylbenzene technology leadership
ExxonMobil continues to be one of the leading EB catalyst suppliers in the world.
Since 2001, almost two-thirds of all new and replacement EB capacity was licensed by Badger and use ExxonMobil catalysts. As of 2017, ExxonMobil catalysts are deployed to some 35 EBMax customers and have enabled new grassroot units, revamps of older technology and expansions of ethylbenzene capacity, including many of the world's largest units. ExxonMobil catalysts account for more than 56% of the world's ethylbenzene production, in excess of 20 million metric tons per year, in the Badger EBMax and Badger Vapor Phase processes.
