摘　　要：在1 L喷淋式反应器中进行甲烷水合实验研究,考察添加剂十二烷基硫酸钠、乙醇和气相压力对喷淋水合过程的影响,得出如下结论:添加剂对水合反应的作用明显,乙醇比十二烷基硫酸钠对水合速率的提高更为显著,0.018mol/L的乙醇溶液的平均进气速率达到0.46V/(V.min),约为0.001 mol/L的十二烷基硫酸钠溶液10倍;水合反应所要求的气相压力大大降低;与半连续搅拌槽式反应器相比,具有气体操作压力低,水合速率高的优点。Experimental investigation of methane hydration was processed in a 1 L ,spraying reactor. Effect of addttives, sodium dodecylsulfate and ethanol, and effect of gas pressure for the hydration process were researched. Some conclusions were drawn as follows： Additive was better choice to increase greatly methane hydration rate. Ethanol as a promoter was better than sodium dodecylsulfate for increasing hydrate reaction rate. Average gas consumption rate was 0.46 V/（V·min） when 0. 018 mol/L ethanol mlutions was reagent, which was approximately 10 times when 0. 001 mol/L sodium dodecylsulfate solutions was reagent. Moreover, pressure of gas phase needed was decreased greatly when hydration reaction was processed. Comparison with semi-CSTR, the advantage of spraying reactor was lower operation pressure needed and higher hydration rate achieved.
