In the present work, molybdenum based catalysts have been investigated for the metathesis of propylene to ethylene and butylene-2 co-corresponding author. With the demand for propylene now exceeding that for c4s, the authors see the integration of the metathesis process in fcc units and steam crackers as a low capital. An ethane or other hydrocarbon feedstock is steam cracked to produce an ethylene stream which is processed in an ethylene plant recovery section to separate an ethane. Ethylene propylene | c5h10 | cid 62702 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities. The metathesis of propylene, the oligomerization and dimerization of ethylene and the isomerization of cis-2-butene were investigated under identical conditions over.

A process for producing propylene from a c 4 feed containing 2-butene includes contacting said feed with ethylene in a metathesis reaction zone containing a. Propylene is typically considered a co-product in steam crackers and fluid-catalytic-cracking (fcc) processes, which are primarily driven by ethylene and motor. Reports emphasize developments for propylene production via metathesis of ethylene and butenes that have potential implications for the chemical and energy industries.
