摘　　要：碳纳米管是具有优良的力学及导热性能的新型纳米材料;碳纳米管的高表面活性及高比表面积使其在水合物生成、提高储气量方面有较好促进作用。为了探索碳纳米管对气体水合物促进生成的影响规律,为后续的实验探究提供方向,本文回顾了近几年国内外开展的水合物生成实验进展,从碳纳米管本身特性、附着基团或嫁接纳米颗粒对促进水合物生成的影响以及不同促进剂体系下碳纳米管对水合物生成的促进作用等方面进行了分析总结。发现模拟方面未考虑孔径分布、基团附着以及堆叠方式等实际因素的影响;改性碳纳米管研究方面,多种具有特殊作用的基团或金属纳米颗粒改性碳纳米管对水合物生成促进的影响有待探索;不同体系下碳纳米管的促进作用研究进行的较少,但已有研究表明复配型促进效果优于单一使用碳纳米管的情况。后续研究中,不同种类改性碳纳米管以及不同体系下碳纳米管对水合物生成的促进作用是重点研究方向。Carbon nanotubes are new nanomaterials with excellent mechanical and thermal conductivity.The high surface activity and specific surface area of carbon nanotubes make them have better roles in promoting hydrate formation and increasing gas storage.In order to explore the influence of carbon nanotubes on the formation of gas hydrate and provide directions for the subsequent experiments,this paper reviewed the experimental progress of hydrate formation carried out at home and abroad in recent years.The influences of carbon nanotubes characteristics and the attachment groups/grafted nanoparticles on the formation of hydrate,and the promotion of carbon nanotubes on the formation of hydrate in different accelerator systems were analyzed and summarized.It is found that the simulation does not consider the factors such as pore size distribution,group attachment and stacking mode.In the research of modified carbon nanotubes,the effects of a variety of special groups/metal nanoparticles modified carbon nanotubes on promoting the hydrate formation need to be explored.There are few studies on the promotion of carbon nanotubes in different systems,while the existing studies show that the promotion effect of the compound type is better than that of single carbon nanotubes.In the following studies,the promotions of different kinds of modified carbon nanotubes and the carbon nanotubes in different systems on hydrate formation are the key research directions.
