Although hydrate-based technology has been considered as a safe and environmentally friendly approach for gas storage and transportation in recent decades, there are still inherent problems during hydrate production, such as a long induction time, slow formation kinetics, and limited hydrate storage capacity. Attempts to resolve these issues have resulted in the development of various kinetics promoters, among which carbon-based materials have become one of the most attractive owing to their unique promotion effect. Herein, results on promotion by bulk wetted carbon materials in the forms of a packed bed, carbon particles in a suspension, and nano-carbon materials in a nanofluid are collected from the published literature. Meanwhile, the promotion mechanisms and influencing factors of the carbon-based promoters are discussed. The purpose of this mini-review is to summarize recent advances and highlight the prospects and future challenges for the use of carbon-based materials in hydrate production.
尽管近几十年来基于水合物的技术被认为是一种用于气体储存和运输的安全且环保的方法，但在水合物生成过程中仍然存在一些固有问题，例如诱导时间长、生成动力学缓慢以及水合物储存容量有限。为解决这些问题所做的尝试导致了各种动力学促进剂的开发，其中碳基材料因其独特的促进作用而成为最具吸引力的材料之一。在此，从已发表的文献中收集了关于填充床形式的块状湿润碳材料、悬浮液中的碳颗粒以及纳米流体中的纳米碳材料促进作用的结果。同时，讨论了碳基促进剂的促进机制和影响因素。本综述的目的是总结近期进展，并突出碳基材料在水合物生成中的应用前景和未来挑战。
