Document Type and Number:
Japanese Patent JP2002531425
Kind Code:
A
Abstract:
An isomerization process for converting an isomerization feed stream containing alkanes having about 4 carbon atoms to about 10 carbon atoms per molecule and cycloalkanes having about 5 carbon atoms to about 10 carbon atoms per molecule to at least one product hydrocarbon isomer. The isomerization feed stream, which contains at least one feed hydrocarbon and hydrogen, is contacted in an isomerization zone at effective isomerization conditions with a catalyst where deactivation of such catalyst occurs in the isomerization zone. The isomerization process includes the presence of an additive in the isomerization feed stream. The concentration of the additive is sufficient to alleviate or diminish the deactivation of the catalyst and to maintain a substantially constant conversion of the at least one feed hydrocarbon to the at least one product hydrocarbon isomer at effective isomerization conditions.
