Abstract
The present disclosure relates to a process for the deolefinization of hydrocarbon streams through an aromatic alkylation reaction by olefins, using a catalyst containing a framework-substituted zirconium and/or titanium and/or hafnium-modified ultra-stable Y (USY) type zeolite.
Claims28
A process for deolefinization of a hydrocarbon feed containing aromatic compounds and olefins, the process comprising the step of contacting the hydrocarbon feed with a catalyst containing a framework-substituted ultra-stable Y (USY)-type zeolite in which a portion of aluminum atoms constituting a zeolite framework thereof is substituted with zirconium atoms and/or titanium and/or hafnium atoms, wherein the olefins alkylate the aromatic compounds in the hydrocarbon feed, thereby producing a deolefinated hydrocarbon product.
A process for alkylating aromatic compounds in a hydrocarbon feed containing aromatic compounds and olefins, the process comprising the step of contacting the hydrocarbon feed with a catalyst containing framework-substituted ultra-stable Y (USY)-type zeolite in which a portion of aluminum atoms constituting a zeolite framework thereof is substituted with zirconium atoms and/or titanium and/or hafnium atoms, wherein the olefins alkylate the aromatic compounds in the hydrocarbon feed, thereby producing alkylated aromatic compounds.
