ABSTRACT:
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.
