A process for producing a product aromatic compound is disclosed which uses an on-stream alkylation reactor and an off-stream alkylation reactor, and in which at least a portion of the feed aromatic compound in the effluent stream of off-stream alkylation reactor undergoing regeneration is passed to the on-stream alkylation reactor. An embodiment of this process that uses on-stream and off-stream aromatic byproducts removal zones is also disclosed.

This invention relates to a dehydrogenation process using a layered catalyst composition. The catalyst composition comprises an inner core such as alpha-alumina, and an outer layer bonded to the inner core composed of an outer refractory inorganic oxide such as gamma-alumina. The outer layer has uniformly dispersed thereon a platinum group metal such as platinum and a promoter metal such as tin. The composition also contains a modifier metal such as lithium. The catalyst composition shows improved durability and selectivity for dehydrogenating hydrocarbons, especially at dehydrogenation conditions comprising a low water concentration.

Aromatic by-products are sorbed from mono-olefin-containing feedstocks of olefins having from about 6 to 22 carbon atoms per molecule that contain aromatic by-products having from 7 to 22 carbon atoms per molecule. A benzene-containing regenerant displaces and desorbs the aromatic by-products from the sorbent and a regeneration effluent is provided. The regeneration effluent is treated in a regeneration effluent distillation system to provide a benzene-rich stream and an aromatic by-products-containing stream. The latter is subjected to benzene-forming conditions and recycled to the regeneration effluent distillation system where benzene is recovered.

The present invention provides a reactor system having: (1) a plurality of reactors connected in fluid flow communication and having at least one pair of reactors separated by an interstage position; (2) a line for supplying a reactant feed stream separately to an inlet of more than one of the plurality of reactors; and (3) a diverter in fluid communication with the interstage position and capable of directing a first portion of a product stream exiting one reactor in said pair of reactors to a first location and a second portion of the product flow stream to an inlet of another reactor in said pair of reactors.

A processing scheme and system for enhanced light olefin production, particularly for increased relative yield of propylene, involves oxygenate conversion to olefins and subsequent oxygenate conversion effluent stream treatment including dimerization of ethylene to butene and metathesis of butenes and/or hexenes with ethylene. The processing scheme and system may further involve isomerization of at least a portion of 1-butene to 2-butene to produce additional propylene.

The activity of a dehydrogenation catalyst is improved by increasing the water concentration maintained in the reactants toward the start of the catalyst's life, but after the catalyst has deactivated to the extent that the temperature required to maintain the conversion per pass of paraffinic hydrocarbon through the reaction zone increases by at least 2 C.
