摘要

为了考察SbSn金属间化合物的制备条件对材料的结构以及脱硫性能的影响，采用不同的熔融温度，配以喷雾快冷法制备了SnSb金属间化合物.用差热分析和XRD对产物进行了测试表征.对产物的结构进行了模拟计算与讨论，给出了产品制备温度分别在750℃和950℃下的分子点群示意图.发现锡锑化合物在升温过程中，熔体的结构会发生变化，不同熔融温度下制备出的材料的晶体结构不同.脱硫实验结果表明，900℃以上熔融喷雾快冷制备出的材料具有较好的脱硫性能.在SnSb和原油乳化液质量比为1∶20的条件下，950℃下，熔融喷雾快冷制备出的材料一次搅拌24 h可以使原油中的硫含量降低2440.0 μg·g-1.

Abstract

In order to investigate the relationship between preparation parameters of SnSb intermetallic compound and its structure and desulfurization performance

SnSb intermetallic compound was prepared by melting at different temperatures combined with spraying quencher.The compound was characterized with DSC and XRD

and its structures were simulated and discussed.The space lattice diagrams of the compound melted at 750℃ and 950℃ were given respectively.It was found that the structure of liquid mixture of tin and antimony changed with the melting temperature

and the crystal structures of SbSn prepared at different melting temperatures were not the same.The results of desulfuration experiment showed that the compound prepared at a melting temperature beyond 900℃ had better desulfurization performance.Under the condition that a mixture of crude oil emulsion and SnSb prepared at melting temperature 950℃ at a weight ratio of 20∶1 being stirred 24 h

the sulfur content of crude oil could be reduced by 2440.0 μg·g-1.
