摘要： 选取绿色、 环保的生物型表面活性剂辛基葡糖苷作为乙烯水合物的生成促进剂进行实验研究, 并简 要探究了其促进机理。首先考察了辛基葡糖苷对乙烯水合物生成条件的影响; 其次考察了辛基葡糖苷对乙烯水合 物生成速率及储气量的影响; 最后利用 H y s y s考察了相平衡条件下乙烯的溶解性。结果表明, 与去离子水体系相 比, 辛基葡糖苷的加入在热力学上对乙烯水合物的影响不大; 在动力学上可显著降低乙烯水合物诱导时间, 生成速 率提升在3倍以上, 储气量的提升在5 0%左右, 其中2 8 3. 1 5K、 2. 2 0MP a下储气量达1 6 4. 7 1, 接近理论储气量; 相平 衡条件下, 乙烯在辛基葡糖苷溶液中的溶解量显著高于去离子水体系, 但远低于水合反应的消耗量。

Abstract: In this paper, the promoting effect of green biological surfactant octylbetaDglucopyranoside on ethylene hydrate formation was experimentally investigated, in futher, the mechanism of promoting was also briefly explored. First, the effect of octylbetaDglucopyranoside on ethylene hydrate formation condition was researched. Then, the effect of octylbetaDglucopyranoside on ethylene hydrate formation rate and storage capacity was also tested. At last, the solubility of ethylene under the condition of phase equilibrium through Hysys was studied. The results show that compare with deionized water system, OctylbetaDglucopyranoside has little effect on ethylene hydrate formation in thermodynamics. While in the kinetics, it can dramaticlly decrease the induction time of ethylene hydrate formation and increase the rate of ethylene hydrate formation more than three times. In addition, the storage capacity can be increased by 50%, under the condition of 283.15 K and 2.20 MPa with storage capacity of 164.71, which is close to the theory storage volume. Under the condition of phase equilibrium, the dissolved value of ethylene in octylbetaDglucopyranoside solution is significantly higher than that in deionized water system, but is far less than the consumption of hydration.
