In recent years, the light olefin manufacturers have often confronted an unpredictable regional supply-demand imbalance between light olefins due to the higher price of propylene and the expectation of an increase of the propylene demand, and sufficient amounts of ethylene from many newly devised ethane crackers using shale gas in the U.S. Therefore, olefin plant requires an olefin interconversion technology as a simple and optional process to respond quickly to the sudden imbalance of light olefins. The olefin interconversion process is typically divided into two processes: the ethylene-to-propylene (ETP) process and propylene-to-ethylene (PTE) process. Our group has been worked on the catalyst design and process development of olefin interconversion technology. Some results on the synthesis of zeolite catalyst used, their catalytic evaluation, and process evaluation for the commercial application will be presented. |
