MIL-101固载磷钨酸催化氧气氧化脱硫性能
Catalytic performance of phosphotungstic acid encapsulated into MIL-101 for oxidative desulfurization with oxygen
摘要
Abstract
A heterogeneous catalyst,chromium terephthalate metal organic framework (MIL-101) encapsulated phosphotungstic acid (HPW),HPW@MIL-101,was prepared by one step method.And then it was used as catalyst in oxidative desulfurization system in which O2 acted as oxidant for the removal of dibenzothiophene (DBT).The effects of oxygen flow rate,sulfur content and reaction temperature on the desulfurization were studied.The results show that the DBT conversion is up to 74％ for 60 min under the optimal reaction condition (sulfur content:350 μg · g-1,oxygen flow rate:90 ml · min-1,the amount of catalyst:1％ the mass of normal octane;reaction temperature:75℃).The DBT conversion doesn't decrease obviously,after reused for three times with this catalyst.And it is possible to use air as green oxidant in desulfurization.关键词
