摘　　要：在"催化氧化脱硫"与"再生"分开的新型LO-CAT脱硫装置中,以海水为吸收介质,络合铁为载体,针对H2S质量浓度为10g/m3的模拟气进行了海上钻井平台石油伴生气脱除H2S的再生系统实验研究。主要考察了再生系统中碱性液体流速、空气过剩因子(ε)和再生温度等参数对脱硫效果的影响,并对反应产生的固体产物进行了SEM和XRD表征。实验结果分析得出,脱除H2S的最佳再生条件为:液体流速v=8.77mL/min,空气过剩因子ε=90,再生温度T2=45℃。表征得出,产生的固体物质为硫磺,可能含有少量Fex Sy杂质。The removal of H2S through seawater in the new LO-CAT desulfurization device which sepa- rate ＂regeneration＂ from ＂catalytic oxidation desulfurization＂ by chelated iron is studied. The effects of so- lution velocity, air （oxygen） excess factor （e） and regeneration temperature in regeneration system on the removal of Hz S （10 g/m3） which exists in the simulated oil associated gas from marine drilling platform are investigated. The solid product is characterized by SEM and XRD. The results show that when solu- tion velocity is 8. 77 mL/min, e is 90 and regeneration temperature is 45 ℃, the optimum regeneration process conditions for H2S removal can be obtained. In addition, the solid product is sulfur, and a small amount of Fe, Sy impurity.
