High production for C₄ olefins as a byproduct in naphtha crackers has stimulated researchers to explore different separation options. Adsorptive separation has been targeted to separate C₄ olefins. In this review, challenges and opportunities in the adsorptive separation of C₄ olefins using microporous zeolites are scrutinized and elaborated. C₄ olefins such as 1-butene, 2-butene, isobutene and butadiene are highly demanded in the petrochemical industry. Their similar properties require highly intensive distillation processes. Adsorptive separation offers lower energy cost, however in the past 70 years, there are limited studies on microporous zeolites for C₄ olefins separation. This review highlights the criteria to produce cost-effective adsorbents with shorter synthesis time, cheaper organic structure directing agent (OSDA), potentially higher capacity and improved regenerability properties. Among more than 200 frameworks, FAU, DDR and CHA are some potential frameworks which have been explored for separation of C₄ olefins. Recent development of these frameworks and their applications in C₄ olefins are carefully studied. It is expected that this review paper will stimulate further exploration of selected zeolites for adsorptive separation of C₄ olefins and open plethora applications in related separations.

石脑油裂化塔中作为副产物的C ₄烯烃的高产量刺激了研究人员探索不同的分离方法。吸附分离的目标是分离C ₄烯烃。在这篇综述中，对使用微孔沸石吸附分离C ₄烯烃的挑战和机遇进行了详细研究和阐述。在石油化学工业中，对C ₄烯烃如1-丁烯，2-丁烯，异丁烯和丁二烯的需求很高。它们的相似性质需要高度密集的蒸馏过程。吸附分离提供了较低的能源成本，但是在过去的70年中，关于C _4的微孔沸石的研究很少。烯烃分离。这篇综述重点介绍了生产具有较短合成时间，更便宜的有机结构导向剂（OSDA），潜在的更高容量和改善的可再生性的具有成本效益的吸附剂的标准。在200多个框架中，FAU，DDR和CHA是为分离C ₄烯烃而探索的一些潜在框架。仔细研究了这些骨架的最新发展及其在C ₄烯烃中的应用。预计该综述文件将刺激对用于C ₄烯烃吸附分离的沸石的选择以及在相关分离中的大量应用。
