At present, the problem of global warming is becoming increasingly serious, and one of the main culprits is the increasing amount of carbon dioxide emissions. Although the traditional carbon capture technologies can reduce the concentration of CO in the atmosphere, it has a series of problems such as high energy consumption, high cost, low efficiency or unfriendly environment. Hydrate-based carbon dioxide separation are considered to be a technology with great application and development prospects. Compared with the traditional method of carbon dioxide separation, the hydrate method has the advantages of simple process, low energy consumption and environmental friendliness. This review introduces the advantages of hydrate method compared with traditional carbon capture technologies, expounds the theory of carbon dioxide capture by hydrate, and the strengthening and improvement techniques of hydrate method, including thermodynamic promoter, kinetic promoter and mechanical reinforcement, and introduces the practical application of hydrate method in various fields.
目前，全球变暖问题日益严重，主要元凶之一是二氧化碳排放量的不断增加。尽管传统的碳捕获技术可以降低大气中二氧化碳的浓度，但它存在一系列问题，如高能耗、高成本、低效率或对环境不友好。基于水合物的二氧化碳分离被认为是一种具有巨大应用和发展前景的技术。与传统的二氧化碳分离方法相比，水合物法具有工艺简单、能耗低和环境友好等优点。本文综述了水合物法与传统碳捕获技术相比的优势，阐述了水合物捕获二氧化碳的理论，以及水合物法的强化和改进技术，包括热力学促进剂、动力学促进剂和机械强化，并介绍了水合物法在各个领域的实际应用。
