摘　　要：通过对喷雾制备甲烷水合物进行实验研究,明确制备水合物的工艺过程和特点,分析了喷嘴喷雾角、气液空间体积比等影响因素,探讨了甲烷水合物的生长机理。实验表明:采用实心45°喷雾角喷嘴的雾化效果最好,反应容器最佳气液相空间体积比约为1∶1;甲烷气体消耗量随着过冷度的增大而增大,而且水合物晶体生长形态差异明显;系统水过冷度作为甲烷水合物生长驱动力,拟合出甲烷水合物生长速率与过冷度的关系式。Based on the experimental study of spray producing methane hydrate, technological process and charac-teristics of producing hydrate are determined, influencing factors such as spray angles of nozzle, space volume ratio of gas and liquid are analyzed, and growth mechanism of methane hydrate is discussed. The study shows that using solid nozzle with 45° spray angle has best atomization effects, the best space ~olume ratio of gas and liquid of reactor is about 1 ： 1, methane gas consumption increases with the increasing undercooling, and the difference in growth morphology of hydrate crystal is obvious . Taking system water undercooling as growth - driving force of methane hydrate, relational expression between methane hydrate growth ratio and undercooling is fitted.
