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.
