Propylene is an important petrochemical industry feedstock. The demand for propylene by the petrochemical industry has increased more rapidly than that for ethylene. The catalytic conversion of surplus C4olefin to propylene can increase the production of propylene and will benefit petrochemical producer. The catalytic conversion of C4 olefins to propylene includes two possible technical routes, one is C4 olefin disproportionation, such as Meta-4 process,BASF process,UOP process,OCT process and Sasol Tech Pty Process;the other route is catalytic cracking of C4 olefin, including Propylur (FBCC) process, MOI process and ATOFINA-UOP process. Advances in catalyst, process technology and techno-economics for catalytic conversion of C4 olefin to propylene were reviewed accordingly. It is imperative to develop effective catalysts and technological process for catalytic conversion of C4 olef ins to propylene in China.
