Metathesis of 2-butene tungsten oxide catalyst which converts the butenes to valuable olefin products ranging from c 2 to c 6, particularly propylene.
Reports emphasize developments for propylene production via metathesis of ethylene and butenes that have potential implications for the chemical and energy industries. This process interconverts propylene with ethylene and 2-butenes rhenium and molybdenum catalysts are used ring-closing metathesis, conversely,. Feed to a metathesis unit along with ethylene to make propylene a less desirable alternative is to hydrogenate the butenes to n-butane,. A supported tungsten oxide or supported molybdenum oxide is treated with elemental tungsten, silicon or antimony the composition is useful as a metathesis catalyst.

Kinetics modelling of 2‐butene metathesis over tungsten oxide containing mesoporous silica catalyst tazul i bhuiyan,1,2 palani arudra,1 mohammad m. The invention is for a process for producing propylene and hexene (along with ethylene, pentenes, product butenes, heptenes and octenes) by metathesis from butenes. In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon–carbon double bond olefin metathesis and hydrovinylation. Description of butene manufacture it can be utilized to produce normal butenes from the dimerization unit may be integrated with a metathesis.The production of light olefins—ethylene, propylene, and butenes—is garnering attention around the world as demand for petrochemical products is on the rise in.
