Abstract
Deactivation of an isomerization catalyst is inhibited by charging a hydrocarbon feed having a concentration of an organic aluminum halide compound to an isomerization zone operating under isomerization conditions and containing an isomerization catalyst.
Claims32
A process comprising charging a hydrocarbon feed having a concentration of at least one organic aluminum halide compound to an isomerization zone operating under isomerization conditions and containing an isomerization catalyst.
An isomerization process comprising the steps of:
- charging a hydrocarbon feed comprising an isomerizable hydrocarbon to an isomerization zone containing an isomerization catalyst, wherein said isomerization zone is operated under isomerization conditions;
- and
- introducing an organic aluminum halide compound into said hydrocarbon feed in an amount that is effective to inhibit deactivation of said isomerization catalyst.
An isomerization process comprising the steps of:
- charging a hydrocarbon feed comprising an isomerizable hydrocarbon to an isomerization zone containing an isomerization catalyst, wherein said isomerization zone is operated under isomerization conditions;
- and
- introducing a first amount of an organic aluminum halide compound and a second amount of a nonmetallic chloride compound into said hydrocarbon feed, wherein said first amount and said second amount are effective to inhibit deactivation of said isomerization catalyst.
