| 摘要: |
| 针对静态条件下水合物形成诱导时间长、生长缓慢、随机性大的问题，实验研究了静态系统中HCFC-141b（R141b）制冷剂水合物的生成促进技术。实验研究了表面活性剂SDS、Cu丝对HCFC-141b水合物形成的促进作用。研究结果表明SDS和Cu丝可大幅缩短HCFC-141b水合物形成诱导时间，促进静态条件下水合物的快速生成。实验发现SDS+Cu丝促进体系中的SDS添加量存在最佳质量浓度，SDS的最佳质量浓度为0.1 %，在此条件下水合物形成平均诱导时间约为1.3 h，水合物生成重复性好，生成的水合物密实。 |

| Abstract: |
| In order to solve the problem that the hydrate grows slowly with a long induction time and randomness, the technology of promoting HCFC-141b（R141b）hydrate formation is studied in quiescent systems. The effect of surfactant SDS and copper wire on HCFC-141b hydrate formation is investigated experimentally. The induction time of R141b hydrate is reduced greatly, and hydrate could form rapidly by adding SDS or (and) copper wire in quiescent systems. The effect of SDS mass concentration on hydrate formation is also studied with copper wire. Experimental results show that the best mass concentration of SDS is about 0.1 %, and the average induction time is about 1.3 h. The repeatability of R141b hydrate formation is good, and hydrate forms compactly. |
