高吸水性树脂—丙烷—水三元共混体系稳定性初探

PRIMARY STUDY ON STABILITY OF SUPER ABSORBABILITY POLYMER-PROPANE-WATER TERNARY BLEND SYSTEM

高吸水性树指—丙烷—水三元共混体系稳定性研究的目的是寻求一种在较低压力和较高温度下保持气体水合物的途径。通过研究网络高分子包裹下气体水合物的稳定性 ,探索网络高分子对于作为气体水合物储运稳定剂的可行性和方式。在 - 2 2℃、0 .2MPa条件下由高吸水性树脂、丙烷、水三元共混体系生成了气体水合物 ,研究该体系在常压下 0℃和 5℃的稳定情况 ,发现高吸水树脂提供了三维网络体系 ,且其具有包裹气体水合物的作用 ,使得已生成的气体水合物在同样条件下更稳定 ,但却不利于气体水合物的生成 ,即对水合物的生成有抑制作用。

To find a way to keep gas hydrate under low pressure and high temperature, with stability study of gas hydrate involved by network high molecular, it is investigated for the feasibility to take the network high molecular as the stable agent of gas hydrate during storage and transportation. Under the conditions of -22℃ and 0.2 Mpa., the super absorbent polymer-propane-water can form gas hydrate. The stability of the ternary system at 0℃ and 5℃ under common pressure has been studied. It is found that the super absorbability polymer provides the 3-D network system, and can involve the gas hydrate to make the gas hydrate more stable under the same conditions, but is unfavorable for hydrate formation.
