Albert H Wu, James T Wei: Cumene synthesis process using purified benzene and propylene feedstock streams. Sunoco, Robert A Koons Jr, Matthew P McWilliams, Pepper Hamilton, March 12, 2002: US06355851 (12 worldwide citation)

A zeolite-catalyzed cumene synthesis process in which benzene and propylene feedstocks are pre-treated to remove catalyst poisons. The benzene feedstock is pre-treated under pressure by contact with a “hot” clay bed at a temperature of about 200 to 500° C., followed by distillation of the benzene fe ...
