摘　　要：为解决当前煤层气开采利用率低且煤层气中氧气和氮气含量较高影响其应用的问题,在对气体水合物生产原理及不同气体所形成水合物稳定性分析的基础上,基于气体水合物方法提纯煤层气设计了实验装置、实验方法和实验过程,重点研究不同浓度TBAC水溶液对煤层气气体水合物相平衡条件和动力性,为后续煤层提纯的实践应用提供指导。In order to solve the problem that the low exploitation and utilization rate of coalbed methane and the high content of oxygen and nitrogen in coalbed methane affect its application,based on the analysis of the production principle of gas hydrate and the stability of hydrates formed by different gases,the experimental device,experimental method and experimental process are designed for purifying coalbed methane by gas hydrate method.The phase equilibrium conditions and dynamics of coal bed gas hydrate with different concentrations of TBAC aqueous solution are mainly studied to provide guidance for the subsequent practical application of coal bed purification.
