A novel silver ion‐exchange treatment of zeolite was introduced in this work to change the
physical and chemical adsorption properties of penetrants in the zeolite. EDX data confirm …

In this work, the zeolite-Y was ion-exchanged by introducing silver cations into the
framework of micro-sized nano-porous sodium zeolite-Y using a liquid-phase ion …

Purification of normal α-olefins by removal of dienes has been demonstrated previously in
our laboratories by π-complexation using Ag+ ion-exchanged zeolite (Ag− Y) or …

Most C4 hydrocarbons are obtained as byproducts of ethylene production or oil refining, and
complex and energy-intensive separation schemes are required for their isolation …

The separation of mixed C4 olefins is a highly energy-intensive operation in the chemical
industry due to the close boiling points of the unsaturated C4 isomers. In particular, the …
