摘要

提出以HCFC-141b的O/W型乳化液形成其气体水合物的设想，且在可控变温仪中进行了程序降温实验。采用的乳化剂为OP-10和SDS。实验结果表明，在静态、高于-5℃的情况下，不同HCFC-141b含量的乳化液均能形成水合物；但诱导期随机性很强，起始水合温度也有一定的波动性；水合物形成前后都会结冰，结冰和加入冰粒都能诱发水合物的快速形成；水合物分解后，液体经再乳化后可以重新使用，其“记忆”效应可使其在1 h内于冰点以上形成水合物。

Abstract

The idea in this study is to form gas hydrate of hydrochlorofluorocarbon HCFC-141b from its O/W emulsion

with OP-10 or SDS as emulsifying reagent

and the programmed cooling experiments were carried out in a controllable air conditioning chamber.The results showed that under static state emulsions containing different contents of HCFC-141b could form hydrates at a temperature above -5℃

with random induction time and fluctuating initiation temperature of hydrate formation.The results also showed that

before and after hydrate formation

the reaction system was iced over

and adding ice particles could induce rapid formation of hydrate.The emulsion from dissociation

by re-emulsification，could form hydrate at a temperature above freezing point within 1 h because of the “memory” effect.
