| 英文摘要 | In this work, we report the catalytic performance of a moo2cl2 anchored metal-organic framework, mo@comoc-4, in the oxidative desulfurization (ods) process on a continuous fixed-bed reactor. mo@comoc-4 was examined as a catalyst in the oxidation of model oils containing dibenzothiophene (dbt), benzothiophene (bt) or 4,6-dimethyldibenzothiophene (4,6-dmdbt). in a 50-h ods reaction of dbt at 70 degrees c, with tert-butyl hydroperoxide (tbhp) as the oxidant, a constant high dbt conversion of nearly 80% was observed along with a high oxidant utility of over 85%, where dbt was converted rapidly into dbt sulfone. xrd and icp analysis show that the structure of mo@comoc-4 was well preserved, with no significant leaching of mo species. in addition, mo@comoc-4 can also oxidize a hydrogenated diesel oil, and 74% sulfur removal efficiency was achieved, with an extraction recovery of 92.5% after acetonitrile extraction. spectroscopic characterization confirmed the formation of a molybdenum peroxide complex from moo2cl2 under tbhp treatment, a plausible catalytic process was proposed based on the experiment evidence as well as ft-ir and ft-fir characterization results. |
