Abstract

An adsorbent consisting of a granular NаX zeolite with a hierarchical porous structure and a high degree of crystallinity and phase purity is used for the efficient drying and purification of natural and associated gases from H₂S. The possibility of using KZhV, MP KAKh, KCh-2, and KR-2 kaolins produced in Russia as temporary binder materials during its production is studied. It is found that KZhV and MP KAKh kaolins do not require additional treatment to prepare such an adsorbent. KCh-2 and KR-2 kaolins require additional dispersion.

用不同的高岭土制备含沸石的吸附剂以高效干燥和净化天然气

摘要一种由具有分层多孔结构、高结晶度和相纯度的粒状 NаX 沸石组成的吸附剂被用于高效干燥和净化天然气及伴生气中的 H2S。研究了在生产过程中使用俄罗斯生产的 KZhV、MP KAKh、KCh-2 和 KR-2 高岭土作为临时粘结剂材料的可能性。研究发现，KZhV 和 MP KAKh 高岭土在制备这种吸附剂时不需要额外的处理。而 KCh-2 和 KR-2 高岭土则需要额外的分散处理。
