摘要
为加快煤矿瓦斯高效清洁利用,利用静态甲烷水合物合成实验装置,在NiMnGa悬浮液中开展了结冷胶和L-色氨酸不同配比条件下的瓦斯水合过程动力学影响实验,探究结冷胶与L-色氨酸对瓦斯水合物生成动力学影响.结果表明:在质量分数为0.03%的L-色氨酸体系中,随着结冷胶质量分数的升高,水合物气体消耗量和气体消耗速率均降低,0.3%结冷胶体系促进效果较好,是0.6%体系气体消耗量的5.8 倍;在结冷胶质量分数为0.3%的体系中加入少量L-色氨酸能够促进甲烷水合物生成动力学进程,0.5%L-色氨酸体系比单独结冷胶体系诱导时间缩短了95.56%,气体消耗量和气体消耗速率分别提高了22.9 倍和36.1 倍.该研究可为静态体系促进气体水合物快速生成提供参考.
Abstract
This paper intends to accelerate the efficient and clean utilization of mine gas.The study works by conducting the experiments on kinetic effects of gas hydrate formation process at different ratios of gelling gum to L-tryptophan in NiMnGa suspension by using a static methane hydrate synthesis experimental device,and exploring the effects of gelling gum and L-tryptophan on the kinetics of gas hydrate formation.The results show that in the L-tryptophan system with a mass fraction of 0.03%,with the increase of the mass fraction of the gelled adhesive,the gas consumption and gas consumption rate of the hydrate de-crease,and the 0.3%gelled adhesive system has a better promoting effect,which is 5.8 times the gas con-sumption of the 0.6%system.Adding a small amount of L-tryptophan to the mass fraction system with gelled adhesives of 0.3%can promote the kinetic process of methane hydrate formation.The 0.5%L-tryp-tophan system shortens the induction time by 95.56%compared to the single gelled adhesive system,and the gas consumption and gas consumption rate increase by 22.9 times and 36.1 times,respectively.This study can provide reference for promoting the rapid generation of gas hydrates in static systems.
