摘　　要：为探寻CO_2-CH_4-N_2-TBAB体系水合分离晶体结构特征,应用激光拉曼光谱仪对4种体系下瓦斯气体水合分离过程进行拉曼测试,获取水合物Raman光谱图,分析不同体系下水合物的的组成类型。结果表明:瓦斯气样G1、G2在纯水体系中均合成CO_2水合物;G1-0.4 mol/LTBAB与G2-0.8 mol/LTBAB溶液在本实验条件下CO2-TBAB水合物;阐述了TBAB对CO_2-CH_4-N_2瓦斯气体水合分离影响机理。This paper is an effort to explore the crystal structure of CO2-CH4-N2-TBAB hydrate sepa- ration system. The exploration is focused on the Raman test of the hydration separation process of the gas in the four systems using Raman spectroscopy, an insight into the hydrate Raman spectra, and an analysis of the composition of hydrates in different systems. The results shows that the gas sample G1 and G2 are synthesized into the CO2 hydrate in the pure water system; under the experimental conditions, G1-0.4 mol/LTBAB and G2-0.8 mol/L TBAB solution are synthesized into CO2 TBAB hydrate. The study describes the mechanism of TBAB effect on the hydration of CO2-CH4 - N2.
