    Abstract: A method of producing an alkylaromatic by the alkylation of an aromatic with an alkylating agent, such as producing ethylbenzene by an alkylation reaction of benzene, is disclosed. The method includes using an H-beta catalyst to minimize process upsets due to alkylation catalyst deactivation and the resulting catalyst regeneration or replacement. The H-beta catalyst can be used in a preliminary alkylation reactor that is located upstream of the primary alkylation reactor. The H-beta catalyst used in a preliminary alkylation reactor can reduce the deactivation of the catalyst in the primary alkylation reactor.

    Abstract: A process for making styrene in a pre-existing facility including an infrastructure capable of producing styrene, wherein the infrastructure includes at least one dehydrogenation unit. The process includes coupling an alkylation unit including an alkylation reactor to the infrastructure and contacting toluene with a C1 source in the presence of a first catalyst and a co-feed in the alkylation reactor to form a first product stream comprising styrene and ethylbenzene. The styrene and ethylbenzene from the first product stream are routed for further processing to a portion of the pre-existing facility.
