    摘要： A process for the transalkylation of benzene, toluene and alkylaromatic hydrocarbons containing nine and ten carbon atoms form alkylaromatic hydrocarbons containing eight carbon atoms has been developed. The fixed bed reaction and adsorption zone contains a transalkylation catalyst and an adsorbent effective to selectively adsorb C.sub.9 and C.sub.10 alkylaromatic hydrocarbon reactants relative to the C.sub.8 alkylaromatic hydrocarbon products. Hydrogen and a desorbent are introduced to a first portion of the zone and an effluent containing at least one C.sub.8 alkylaromatic hydrocarbon product is withdrawn from a second portion of the zone. After a period of time, the desorbent is redirected to the second portion of the zone and concurrently the effluent containing at least one C.sub.8 alkylaromatic hydrocarbon product is withdrawn from the first portion of the zone. The alternation of introducing the desorbent to a first portion and then a second portion of the zone while concurrently withdrawing the effluent from the second portion and then the first portion of the zone is continued, thereby retaining the C.sub.9 and C.sub.10 alkylaromatic hydrocarbons within the zone until they are consumed.

    摘要： A process for producing at least one C.sub.8 alkylaromatic hydrocarbon product from a feedstock containing at least one C.sub.9 or C.sub.10 alkylaromatic hydrocarbon reactant using simulated moving bed reactive chromatography has been developed. At least a portion of the reactants are transalkylated to form at least one product in a zone of the simulated moving bed with concurrent separation of at least one alkylaromatic hydrocarbon using the adsorbent. The adsorbed alkylaromatic hydrocarbon is desorbed from the adsorbent in a subsequent zone of the simulated moving bed and the transalkylation of the reactants with concurrent separation of at least one alkylaromatic hydrocarbon using the adsorbent is continued.
