Chemical and petrochemical companies are increasingly realizing that their sustainable development critically depends upon development of new innovative processes that use more efficiently materials and energy. As overall separation/purification processes account for 40–60% of capital and operating costs, their amelioration can significantly reduce costs, energy use and waste generation by increasing profits. Gas separation by adsorption technology is a well-established unit operation in chemical and petrochemical industries due to its efficiency for dealing with a large range of gas separations including impurity removal, gas purification, and separation in recycle streams. The technology is far from being mature and opportunities to expand its domain of applicability and improve its efficiency are high in a context where better understanding of physical phenomena and technological progress in materials and engineering research are integrated. Major contribution for innovations in gas separation by adsorption technology relates to the discovery of new adsorbents with better separation characteristics coupled to process development and its optimization using multi-objective and multi-domain numerical approaches. This short review identifies technological gaps and drivers for accelerating the development of industrially important gas separations by adsorption.

化工和石化公司越来越意识到，其可持续发展在很大程度上取决于开发新的创新工艺的过程，这些工艺将更有效地利用材料和能源。由于总体分离/纯化过程占资本和运营成本的40-60％，因此改善这些过程可以通过增加利润来显着降低成本，能源消耗和废物产生。通过吸附技术进行气体分离是化学和石化行业中公认的单元操作，这是由于其可处理各种气体分离（包括杂质去除，气体净化和循环流中的分离）的效率。在将对物理现象的更好理解与材料和工程研究的技术进步相结合的背景下，该技术还远远没有成熟，扩大其适用范围并提高其效率的机会很高。吸附技术在气体分离方面的创新的主要贡献在于发现了具有更好分离特性的新型吸附剂，这些吸附剂与工艺开发相结合，并使用多目标和多域数值方法对其进行了优化。这篇简短的综述指出了技术差距和驱动因素，这些问题和因素通过吸附加速了工业上重要的气体分离的发展。吸附技术在气体分离方面的创新的主要贡献在于发现了具有更好分离特性的新型吸附剂，这些吸附剂与工艺开发相结合，并使用多目标和多域数值方法对其进行了优化。这篇简短的综述指出了技术差距和驱动因素，这些问题和因素通过吸附加速了工业上重要的气体分离的发展。吸附技术在气体分离方面的创新的主要贡献在于发现了具有更好分离特性的新型吸附剂，这些吸附剂与工艺开发相结合，并使用多目标和多域数值方法对其进行了优化。这篇简短的综述指出了技术差距和驱动因素，这些问题和因素通过吸附加速了工业上重要的气体分离的发展。
