R141b气体水合物的晶体结构与结晶特性分析
Analysis of Crystal Structure and Crystallization Characteristics of R141b Gas Hydrate
摘要
Abstract
Experimental setup for producing R141b gas hydrate crystal and its structure determination by X-ray diffraction (XRD) was designed, and the hydrate crystal was prepared using 0.10 g SDS as the surfactant. The reaction temperature curve of the preparation process and the X-ray diffraction pattern of the experimental samples were obtained to confirm that only type II clathrate hydrate crystal was formed. Diffraction patterns of the samples were quantitatively analyzed using an adiabatic method, and the results show that the amount of R141b in sample preparation has direct impact on average mass ratio and two-phase distribution of II and Ih crystals. The reaction temperature curve and the diffraction patterns combined with crystallization theory of gas hydrate indicate that the amount of R141b has key effects on crystallization micro-environment, which leads to the difference of results from the reaction temperature curve and diffraction patterns.关键词
