摘　　要：围绕静态超重力水合反应器构建了一套气体水合物连续生产工艺,考察了该反应器内超重力因子对CO2水合物生成过程中一些重要参数的影响.实验发现,CO2水合物生产速率与超重力因子成指数增长关系,超重力因子为390.285时,CO2水合物生产速率达到最大值36.85 kg/h.在实验范围内CO2气体转化率与超重力因子的关系曲线类似抛物线,超重力因子大约为250左右时CO2气体转化率达到峰值,但总体上转化率不大于27%.同时,对新型水合反应器内CO2水合物生产过程的热量进行分析发现,实验范围内水合反应器热量利用的效率与超重力因子成线性增长关系,其最大值为87.39%.In this paper, a static high gravity gas hydrate reactor was introduced into, and the CO2 gas hydrate formation process was continuous with the processing equipment. The influence of the high gravity factor on the important parameters during the CO2 hydrate formation process in the new hydrate reactor was investigated. It was shown that the CO2 hydrate formation rate increased with the high gravity factor by the exponential func- tion. When the high gravity factor was 390. 285, the maximal value of the CO2 hydrate formation rate was up to 36.85kg/h. Within the experiments, the change process was similar to a parabola between the CO2 gas per- cent conversion rate and the high gravity factor. When the high gravity factor was about 250, the CO2 gas con- version was up to the perk value, but on the whole of it was not more than 27%. Besides thermal analysis on the processes were investigated with the high gravity factor from 20. 162 to 390. 285. It was found that the en- ergy utilization efficiency increased as a linear function with the high gravity factor, which the maximum value was 87.39%.
