杂多酸相转移催化剂在柴油氧化脱硫中的应用

研究制备含有Keggin结构的杂多酸相转移催化剂。分析该催化剂在柴油的空气氧化脱硫反应中的催化效果。氧化后柴油中的硫氧化物，从油品中萃取分离出来，以达到降低油品硫含量的目的。实验结果表明：在酸性条件下(pH=2~3)，常温反应3小时，以极性溶剂萃取分离后，柴油的硫含量可降低85%以上。并通过WK-2D微库仑综合分析仪、红外光谱（FT-IR）等分析测试手段，研究杂多酸相转移催化剂在柴油空气氧化脱硫工艺中的催化作用。

Application of Diesel Oxidize Desulphurization with Heteropoly Acids Catalyst

The phase transfer catalyst agent is prepared by heteropol acid which contained a Keggin structure. It can be used in catalysis oxidative reaction, and the organic sulfurous compound can be inverted to more polarity oxysulfide sulfoxide with it. Separate oxysulfide sulfoxide from oil, the sulfur content of oil can be reduced. Study on the catalysis of air-oxidate desulfurization of diesel oil by WK-2D Decline Coulomb Integrate Analyzer and infrared spectrometric analyzer. The result showed that under the condition of acidic circumstance (pH=2~3), at the room temperature, a three hours reaction process, and extract by the polarity solvent, the sulfur content of oil can reduced more than 85 percent.
