摘  要:针对天然气水合反应进程缓慢、生成量低等动力学问题,本文在磁场作用下将NiMnGa磁性微纳米颗粒与十二烷基硫酸钠(SDS)和低浓度四氢呋喃(THF)复配开展甲烷(CH_(4))水合物生成动力学研究,考察复配体系对CH_(4)水合动力学影响。结果表明:NiMnGa微纳米颗粒协同动态磁场作用可有效缩短CH_(4)水合物诱导时间、提高气体消耗量;进一步添加少量THF能够将诱导时间缩短至2 min,并将气体消耗量提高了15.2%,适当解决因THF占笼因素导致的气体消耗量低的问题,且与其他体系相比提高气体消耗速率效果最优,该体系可有效强化CH_(4)水合物快速生成,本研究为促进天然气水合物利用技术应用提供了借鉴。To address the kinetic problems such as the slow process and low production of the natural gas hydration reaction,this paper presents a kinetic study of methane(CH_(4))hydrate production by compounding NiMnGa nano-particles with sodium dodecyl sulfate and low-concentration tetrahydrofuran(THF)under the action of a magnetic field and an examination of the effect of the compounding system on CH_(4)hydration kinetics.The results show that NiMnGa nanoparticles incorporated with dynamic magnetic field action effectively reduce the induction time and in-crease the gas consumption of CH_(4)hydrate;further addition of a small amount of THF reduces the induction time to 2 min and increases the gas consumption by 15.2%,which appropriately solve the problem of low gas consumption because of the factor of cage occupation by THF.Moreover,compared with other systems,it increases the gas con-sumption rate with the optimal effect.This system effectively strengthens the rapid generation of CH_(4)hydrate,and this study provides a reference for promoting the application of natural gas hydrate utilization technology.
