WebThe first liquid-phase EB unit, which used a zeolitic catalyst, was commercialised in 1990. This technology, which was developed through the joint efforts of Lummus and Unocal over a period of more than seven years, is now licensed as the Lummus/UOP liquid-phase EB process. Currently, four commercial plants using the process are in operation. WebThe development of a highly efficient strategy for the activation of the C–H bond in hydrocarbons is one of the most challenging tasks facing the chemical industries. The synthesis of novel catalysts with atomically dispersed active centers is highly desirable to achieve the maximized atom efficiency.
