摘要： A method for the production of an adsorbent, having increased capacity for olefins and decreased catalytic activity for polymerization and isomerization, useful in the separation of olefins from a hydrocarbon mixture comprising olefins and paraffins. The methods basically comprises contacting a precursor mass comprising sodium X or sodium Y zeolite and amorphous material selected from the group consisting of silica, alumina and silica-alumina mixtures and compounds as a binder with an aqueous sodium hydroxide solution to increase the sodium cation content of the zeolite and to remove a small portion of silica and alumina; washing the zeolite with water to remove excess caustic solution; and, drying the zeolite to reduce the volatile content.

摘要： An improved process for the separation of olefins from a hydrocarbon feed mixture comprising olefins and saturates which process uses an adsorbent comprising sodium type X or sodium type Y zeolite to selectively adsorb the olefins. The improvement comprises employing an adsorbent produced by the steps of: contacting a precursor mass comprising type X or type Y zeolite having a Na.sub.2 O/Al.sub.2 O.sub.3 ratio less than about 0.7 with an aqueous sodium hydroxide solution at ion exchange conditions to effect the addition of sodium cations to the mass and the removal of a small amount of silica and alumina, washing the mass with water to remove excess sodium hydroxide solution; and, at least partially dehydrating the mass at dehydrating conditions thereby producing an adsorbent which has both increased capacity for olefins and decreased catalytic activity.

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.
