采用鼓泡装置研究了盐水体系中环戊烷(CP)-甲烷水合物的生成动力学,分别考察了进气速率、温度、压力对水合物生成速率和进气速率对气体转化率的影响。结果显示,提高进气速率、压力,降低温度均可提高水合物生成速率。但进气速率对气体转化率有影响,进气速率过大,单位时间内进入到反应器内的气体过多,气体还未参与反应便被排出,导致气体转化率反而减小。通过观察到的实验现象,分析环戊烷-甲烷水合物的生成过程,认为水合物晶体首先在环戊烷-水界面生成,并逐步向内部气相生长,最后水合物壳破裂,气泡逸出。水合物逐渐生长成粒状,并不断聚集在一起。 |

The formation kinetics of cyclo-pentane(CP)-methane hydrate in NaCl solution were studied using a bubbling equipment. The effect of gas-flow rate,temperature and pressure on the hydrate formation rate and the effect of gas-flow rate on the gas conversion rate were investigated. The results showed that increasing the gas-flow rate,pressure and decreasing the temperature could enhance the hydrate formation rate. But the gas-flow rate affected the gas conversion rate. If the gas-flow rate was too high,the gas entering the reactor was discharged before completing the reaction,which yielded the low gas conversion rate. The observation of the process of CP-CH_4 hydrate found thatthe hydrate crystals first generated in the CP/water interface,then grew gradually in internal gas phase until the hydrate shell broke and the bubbles escaped. |
