摘　　要：提高水合物生成速度与生成量是利用水合物法气体分离技术高效利用瓦斯的关键。利用自主搭建的瓦斯水合物合成与分解循环装置,开展了3种不同质量分数的四丁基氯化铵(TBAC)溶液中瓦斯水合分离实验。结果表明,不同质量分数的溶液体系均能在50 min内生成水合物。在相同的时间内,质量分数为5.0%的TBAC溶液获得最大的气体消耗量,平均生长速率达到了2.907 cm^3/min,瓦斯气体中CH4体积分数占比下降了20%,促进效果最佳;质量分数为2.5%的次之;质量分数为7.5%的诱导时间最短,但气体消耗量极少。The promotation of formation of hydrate and its production hold the key to the efficient utilization of gas by hydrate gas separation technology.This paper describes gas hydration separation experiments in three different concentrations of tetrabutyl ammonium chloride(TBAC)solution using a self-built gas hydrate synthesis and decomposition circulating device.The results show that different concentrations of solution systems allows for hydrate formation within 50 min in;within the same time;and 5.0%TBAC solution enables the best promotion effect due to its ability to achieve the maximum gas consumption,at the average growth rate up to 2.907 cm^3/min,and with a 20%decrease in the proportion of CH4 concentration in gas;and this is followed by 2.5%TBAC solution and by 7.5%TBAC solution with the shortest induction time,but with the minimum gas consumption.
