METHOD OF IMPROVING OLEFIN ISOMERIZATION

A skeletal isomerization process for isomerizing olefins is described. The process includes the steps of feeding an olefin-containing feed to a reactor at a space velocity of 1-100 hr−1 for a first period of time at a first temperature, followed by discontinuing, or stopping, the olefin-containing f...

Summary:A skeletal isomerization process for isomerizing olefins is described. The process includes the steps of feeding an olefin-containing feed to a reactor at a space velocity of 1-100 hr−1 for a first period of time at a first temperature, followed by discontinuing, or stopping, the olefin-containing feed for a second period of time while maintaining the reactor at a second temperature, before resuming the flow of the olefin-containing feed for a third period of time. The methods of this disclosure increase the yield of the skeletal isomers product while reducing the production of C5+ heavy olefins. Additionally, the methods of this disclosure can be applied to feeds containing iso-olefins (for the production of linear olefins) or linear olefins (for the production of iso-olefins).
