以SBA-15分子筛为载体、磷钨杂多酸（HPW）为活性组分,制备磷钨酸负载型催化剂.以HPW/SBA-15为催化剂、双氧水为氧化剂对模拟柴油进行催化氧化脱硫研究,考察磷钨酸负载量、反应时间、温度和剂油比对脱硫率的影响,得到了优化的催化氧化条件：磷钨酸负载量为30%,反应温度80℃,反应时间60min,剂油比1︰6时,脱硫率可达97.8%.
以SBA-15分子篩為載體、燐鎢雜多痠（HPW）為活性組分,製備燐鎢痠負載型催化劑.以HPW/SBA-15為催化劑、雙氧水為氧化劑對模擬柴油進行催化氧化脫硫研究,攷察燐鎢痠負載量、反應時間、溫度和劑油比對脫硫率的影響,得到瞭優化的催化氧化條件：燐鎢痠負載量為30%,反應溫度80℃,反應時間60min,劑油比1︰6時,脫硫率可達97.8%.

The supported phosphotungstic acid catalyst was prepared,in which SBA-15 was used as carrier and phosphotungstic acid as active constituent.The oxidative desulfurization from model diesel was studied by using HPW/SBA-15 as catalyst,H2O2 as oxidant.The effect of the loading amount of HPW on SBA-15,reaction time,reaction temperature,volume ratio of oxidant to model diesel on desulfurization rate has been investigated.The optimal catalytic oxidation conditions of DBT are as follows： the loading amount of HPW on SBA-15 is 30%,the reaction temperature is at 80 ℃,reaction time 60 min and the volume ratio of oxidant to model diesel is 1：5,the desulfurization rate is up to 97.8%.
