MoO3/介孔Al2O3催化氧化脱除模拟油中的硫
Catalytic Oxidative Desulfurization of Model Oil by MoO3/Mesoporous Al2O3
摘要
Abstract
In the MoO3/mesoporous Al203-H2O2 system, a simulated oil consisting of model sulfur compounds, such as benzothiophene (BT), dibenzothiophene (DBT), 4,6-dimethyldibenzothiophene (4,6-DMDBT) and thiophene(Th) and cyclohexane as solvent was employed in the oxidative desulfurization study. The effects of catalyst, dosage of oxidation agent and reaction condition on desulfurization activity were investigated. It was shown that the removal efficiency of DBT at 60 ℃ was as high as 99.4% when the content of MoO3, dosage of catalyst and the molar ratio of H202 to sulfur were 20% ,1.5% and 4, respectively. Under the optimum conditions, the oxidative activity of the model sulfur compounds follows the order of DBT >4,6-DMDBT > BT > Th.关键词
