Abstract
A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle.
Claims15
A process for the double-bond isomerization of olefins, the process comprising:
- contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst comprising a structure stabilizing agent, to convert at least a portion of the olefin to its isomer;
- wherein a process for preparing the isomerization catalyst comprises coextruding an admixture of the basic metal oxide and colloidal silica.
A process for the double-bond isomerization of olefins, the process comprising:
- contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst having an effective diameter in the range of 0.25 mm to 4.0 mm to convert at least a portion of the olefin to its isomer;
- wherein a process for preparing the isomerization catalyst comprises coextruding an admixture of the basic metal oxide and colloidal silica.
