Abstract

A process of removing methanol, CO2, or both from a hydrocarbon stream is described. The process uses an adsorbent comprising binderless type 3A zeolite. The adsorbent has high methanol removal capacity and low olefin co-adsorption capacity, as well as low reactivity in an olefin stream. This allows reduced adsorbent loading while maintaining downstream catalyst performance and product quality. The adsorbent comprises a type 3A zeolite comprising less than 5% of a binder and an ion exchange ratio of 30% to 70%. The adsorption process can obtain an outlet methanol content of 1 ppmw or less.
