新型硫醇氧化双功能催化剂CoSPc/Mg(Al)O的研究

摘要

在实验室以镁铝氧化物固溶体(Mg(Al)O)固体碱负载磺化酞菁钴(CoSPc)制成的双功能催化剂 ， 对硫醇氧化反应具有良好的催化活性。载体的碱性强弱、催化剂制备过程中使用的溶剂 种类及催化剂中溶剂的含量对催化剂活性有显著影响。不同结构硫醇氧化反应结果表明， 大分子、异构硫醇较难氧化。此外， 利用双功能催化剂进行了小型固定床喷气燃料脱臭试 验， 取得了初步成果。%Bifunctional catalyst using Mg /Al oxide solid solution as carrier impregnated with cobalt phthalocyanine sulfo nates (CoSPc) was prepared in the laboratory. The test result showed that the sa id catalyst had good catalytic activity. The basicity of the carrier, and the im pregnated solvents and their amounts remained in the catalyst could greatly infl uence the catalyst activity. Different structure thiols oxidation indicated the macromolecular and isostructure thiols were difficult to be oxidized. The jet fu el sweetening conducted on a fixed bed reactor over the said catalyst showed goo d result.
