    摘要： An improvement in the operation to a catalytic distillation process for the alkylation of organic aromatic compounds with an olefin contained wherein aliphatic compounds are contained in either the olefin feed stream, the aromatic feed stream or both is disclosed. Aliphatic compounds are added to the upper portion of a secondary distillation column reactor wherein aromatic is being reacted with unreacted olefin from a primary distillation column reactor to polish the conversion of olefin. The additional aliphatic compound produces an equilibrium in the secondary column wherein unreacted aromatic and alkylation product are recovered as bottoms which may be recycled to the primary distillation column reactor.

    摘要： An adsorptive separation process is disclosed for separating para-aromatic isomers from a hydrocarbon feed containing a mixture of aromatic isomers, using a crystalline aluminosilicate adsorbent which has been treated with an alkyl amine preferably an alkyl amine hydrochloride. The alkyl amine treatment substantially increases the selectivity of the adsorbent for the para-xylene isomer, relative to the heavy desorbent p-DEB, thereby improving the efficiency of the separation process.
