Two New On-Purpose Processes Enhancing Propene Production: Catalytic Cracking of C4 Alkenes to Propene and Metathesis of Ethene and 2-Butene to Propene

A brief review of the work carried out at Dalian Institute of Chemical Physics, Chinese Academy of Sciences for development of two new on-purpose processes enhancing propene production is presented. This includes the processes of catalytic cracking of C4 alkenes to propene and metathesis of ethene and 2-butene to propene, by which the large amounts of the C4 recourses from the petrochemical can be upgraded and the severity of demand for propene can be lessened.
