Abstract
|
Describes
synthesis of ZSM-5/SBA-15 composite molecular sieves using post-synthesis method. Researchers
studied the oxidative-extration desulfurization of model oil using hydrogen
peroxide as the oxidant, tetrabutyl ammonium bromide as phase transfer
catalyst, dimethyl sulfoxide as extractant, and Zr-ZSM-5/SBA-15,
Ag-ZSM-5/SBA-15, Ce-ZSM-5/SBA-15 as catalyst.
Under optimal conditions, the desulfurization rate decreases in the order: Zr-ZSM-5/SBA-15>Ce-ZSM-5/SBA-15 > Ag-ZSM-5/SBA-15. The highest desulfurization rate is 84.53% under the catalysis of Zr-ZSM-5/SBA-15. Kinetics analysis shows that the reaction is pseudo-first-order with the activation energy of 44.23 kJ/mol. |
