摘要

以锡锑金属间化合物作为介质，进行脱除汽油中硫的研究.采用熔融喷雾工艺制备锡锑金属间化合物，作为汽油脱硫功能材料.在汽油中加入水和表面活性剂制成油包水型乳状液，在常温常压下，用SnSb脱除乳化汽油中的硫.通过静态脱硫实验考察了SnSb制备温度、油剂比、处理时间、颗粒大小对脱硫效果的影响.测定了动态脱硫数据，并考察了施加直流电场对动态脱硫效果的影响，考察的电压范围为-15～+15V.结果表明：动态操作时脱硫率远高于静态操作时的脱硫率;电场的方向与大小对脱硫率有显著的影响;配以2.5 V的正电场，对汽油中硫的单程脱除率最大可达45％以上.

Abstract

Using SnSb intermetallic compound to remove sulfur from gasoline was studied.The SnSb intermetallic compound was prepared by fusion-spraying，and used to remove sulfur from emulsified gasoline under normal pressure and temperature.Gasoline was first emulsified with water and surfactant to make water-in-oil emulsion.Several parameters which affect the efficiency of desulfurization were investigated and compared through the static desulfurization process，including preparation temperature of SnSb，proportion of SnSb to oil，reaction time and size of SnSb particles.The dynamic data of desulfurization under different direct current electric fields ranging from -15V to +15V were measured.The experimental results showed that the desulfurization efficiency of the dynamic process was much higher than that of the static process，the efficiency could be improved or reduced according to the direction and magnitude of the electric field imposed，and the highest desulfurization efficiency was above 45% in a single pass under a positive electric field of 2.5 V.
