摘　　要：为探讨瓦斯水合反应过程的温度场分布特征及传热规律,研究两种体系甲烷水合反应过程的反应热和温度场分布。根据实验数据,结合反应热计算方程,计算两种体系的反应热,分析非离子表面活性剂失水山梨醇单硬脂酸酯(Span60)对甲烷水合过程温度场的影响。结果表明:Span60可以提高水合物的生成量,水合过程的反应热增多,进而提高反应体系的温度以及温升速率。通过分析Span60的分子结构,从微观角度提出Span60促进甲烷水合物生成的机理。该研究可为瓦斯水合固化分离与储运技术应用提供理论支撑。This paper is an effort to investigate the distribution characteristics and heat transfer law underlying the temperature field in the gas hydrate formation and decomposition process, together with the reaction heat and temperature field distribution in two systems. The investigation building on the experi- mental data and the equation for reaction heat calculation is focused on the calculation of the reaction heat in the two experimental systems; and the research into the effect of the addition of non-ionic surfactant sorbitan monostearate（Span 60） on the methane hydration reaction system temperature field. The results demonstrate that the addition of Span 60 enables an increase both in the number of methane hydrates and in the quantity of corresponding reaction heat, thereby increasing the temperature of the hydration reaction system and therefore the rate of temperature; and the analysis of the molecular structure of Span60 leads to the mechanism that Span60 provide theoretical support for the could promote the methane hydration formation. The research could application of gas hydrate solidification separation and storage and transportation technology.
