摘要
以壳聚糖无纺布(CS)为载体,将杂多酸盐键接到无纺布中,考察CS负载磷钨酸盐催化剂的脱硫效率。结果表明,最佳脱硫条件为50℃,催化剂为0.1-[SOeBim]PW12O40/CS,氧硫1∶5,催化剂的用量为1.0 g/L,脱硫率达85.5%。
The chitosan non-woven fabric(CS)was used as the carrier to bond the heteropoly acid salt to the non-woven fabric.The desulfurization efficiency of the CS-loaded phosphotungstate catalyst was investigated.The results showed that the optimum desulfurization condition were:the catalyst was 0.1-[SOeBim]PW12O40/CS,at 50℃,the oxygen/sulfur ratio was 1∶5,the catalyst dosage was 1.0 g/L,the desulfurization rate reached 85.5%.
