1,3-二氧五环作用下多孔介质固载甲烷水合物生成规律研究
Researchon the formation rules of methane hydrate loaded by porous media in the presence of 1,3-dioxolane
摘要
Abstract
The low energy consumption and mild storage and transportation conditions of the clathrate-based solid natural gas technology make it a key factor in promoting the development of the natural gas industry.However,the slow hydrate formation kinetics has hindered its application.This article explores the formation laws of methane hydrates supported by porous media(activated carbon and quartz sand)under the action of 1,3-dioxolane.It analyzes the hydration efficiency in different systems,evaluates the synergistic and antagonistic effects of 1,3-dioxolane and porous media on hydrate growth,and clarifies the influence of the pore structure.The results show that:under high pressure,the adsorption of 1,3-dioxolane by the pore structure of activated carbon leads to an antagonistic effect between the two,resulting in poor hydration efficiency.Moreover,as the initial pressure and the concentration of 1,3-dioxolane increase,the antagonistic effect intensifies.Under low pressure,there is a synergistic effect b,etween 1,3-dioxolane and activated carbon.The hydration efficiency is affected by pressure.The free 1,3-dioxolane enhances the formation of methane hydrates and increases the gas storage capacity of hydrates.1,3-Dioxolane enhances the formation of hydrates in the quartz sand system.However,the rapidly growing hydrates limit the conversion of internal water,making this enhancement effect achieve the best performance when the initial pressure is 5 MPa.关键词
