摘要： Methods and processes for reducing alkylation catalyst poisoning are described herein. Such methods generally include contacting ethylbenzene with a dehydrogenation catalyst to form a dehydrogenation output stream within a dehydrogenation system and passing at least a portion of the dehydrogenation output stream to an alkylation system, wherein the at least a portion of the dehydrogenation output stream contacts an alkylation catalyst. The at least a portion of the dehydrogenation output stream includes a level of impurities resulting from offtest and wherein the level of impurities is sufficiently low to result in essentially no observed effect on the alkylation catalyst life in comparison with an alkylation system feed absent offtest.

摘要： Process for the alkylation of an aromatic substrate with partial recycling of the alkylated product. A feedstock comprising an aromatic substrate and an alkylating agent is introduced into an alkylation reaction zone and into contact with a molecular sieve catalyst to produce an alkylation product which is withdrawn from the alkylation reaction zone and split into two portions. A first portion is recycled back to the alkylation reaction zone and supplied to the alkylation zone. A second portion is supplied to a suitable recovery zone for the separation of alkylated aromatic components from the unreacted aromatic substrate. The alkylation reaction zone may be operated under conditions in which the aromatic substrate is in the supercritical phase, and may comprise a plurality of catalyst beds wherein the recycled portion of the alkylation reaction product is subdivided into subproducts with one subproduct recycled to the inlet of the alkylation reaction zone and another subproduct introduced into the alkylation reaction zone between catalyst beds.

摘要： A feedstock containing a C 2 or C 3 alkyl aromatic and steam is supplied into the inlet of a tubular reactor containing a dehydrogenation catalyst and comprising a hydrogen permeable outer wall (30). The alkyl aromatic compound is dehydrogenated to a corresponding vinyl aromatic compound with the attendant production of hydrogen. The feedstock and products of the dehydrogenation reactor are flowed along a longitudinal spiral flow path (34) providing for an outward radial flow of hydrogen to provide a pressure gradient through the hydrogen permeable outer wall (30) the reactor with the flow of hydrogen therethrough. Hydrogen is removed from the outer wall of the reactor. The resulting vinyl aromatic product is recovered from the tubular reactor.
