摘　　要：以正辛酸⁃氯化锌型低共熔溶剂(OA⁃ZnCl_(2))为添加组分、硅胶(SG)为载体,经溶胶⁃凝胶过程合成OA⁃ZnCl_(2)/SG负载型催化剂。采用红外光谱、X射线衍射、N_(2)⁃吸附脱附和扫描电镜等技术对催化剂的结构进行分析。以OA⁃ZnCl_(2)/SG为吸附剂和催化剂、双氧水为氧化剂,研究其氧化脱硫性能。考察了低共熔溶剂的负载量、反应温度、n(H_(2)O_(2))/n(S)、催化剂质量和不同硫化物对脱硫效果的影响。结果表明,在最佳条件下催化剂的脱硫率达到95.6%,经过5次循环后脱硫率降为89.7%。OA⁃ZnCl_(2)/SG supported catalyst was synthesized by sol⁃gel process using octanoic acid⁃zinc chloride deep eutectic solvents(OA⁃ZnCl_(2) DESs)as additive.The structure of the catalyst was analyzed by infrared spectroscopy,X⁃ray diffraction,N_(2) adsorption⁃desorption and scanning electron microscopy.The performance of oxidative desulfurization was studied by using OA⁃ZnCl_(2)/SG as adsorbent and catalyst,and hydrogen peroxide as oxidant.The loading dose of DESs,reaction temperature,n(H_(2)O_(2))/n(S)ratio,the amount of catalyst and the effect of different sulfides on desulfurization rate were investigated.The results show that the desulfurization rate of the catalyst reaches 95.6%under the optimal conditions,and after 5 cycles,the desulfurization rate drops to 89.7%.
