The production of zeolite-containing adsorbents using various kaolins for efficient dehydration and cleaning of natural gas

Abstract

The paper explores the possibility of using KZhV, MP KAH, KCh-2 and KR-2 kaolins produced in Russia as a temporary binder for the production of granulated zeolite NаX, which has high crystallinity and phase purity and a hierarchical pore structure. This zeolite serves as the adsorbent for efficient dehydration of natural and casing-head gases and their cleaning to remove H2S. It was found that KZhV and MP KAH kaolins do not require additional treatments for the production of the indicated adsorbent, whereas KCh-2 and KR-2 kaolins should be additionally dispersed.
