RESEARCH PROGRESS OF ZEOLITE ADSORBENTS FOR SEPARATION OF C2 HYDROCARBONS

Abstract

Abstract: The efficient separation of ethane, ethene, and ethyne represents the pivotal yet unresolved technical challenge in the chemical industry. While conventional high-pressure cryogenic distillation enables component isolation, its substantial energy demands critically hinder sustainable industrial development. In the context of the "Dual Carbon" strategic initiative, zeolite-based adsorption separation technology has emerged as a prominent research frontier owing to its energy-efficient operation, exceptional selectivity, and environmentally friendly characteristics. This review systematically summarizes recent cutting-edge advances in zeolitic adsorbents for C₂ hydrocarbon separations, elucidates fundamental structure-activity relationships and separation mechanisms, and points out that rational engineering of zeolitic pore microenvironments, development of precision-controlled multicomponent separation systems, and developing scale-up production methods for supporting industrial zeolite adsorbents are key future research directions.

Key words: ethane, ethene, ethyne, zeolite, adsorption, separation
