常温常压D072树脂氧化吸附油品脱硫的研究

采用ODS方法,讨论了以D072树脂为催化剂,双氧水为氧化剂脱除汽油中含硫化合物的实验规律。实验采用14 mL汽油,5 g处理后的树脂,一定量H₂O₂,0.1 g Span 60充分搅拌,每30 min监测油品中硫含量,反应2 h后用NMP(N-甲基吡咯烷酮),剂油比为1/2萃取。主要考察反应温度(室温、40 ℃、60 ℃、80 ℃),氧化剂用量(O/S=0、O/S=17、O/S=34)对脱硫效果的影响。结果表明,常温常压下O/S为17时脱硫率最佳,达到75%。

Catalytic oxidative desulfurization of gasoline over D072 resin at room temperature and atmospheric pressure

In order to meet more and more strict policy of environment protection,an investigation into the oxidative desulfurization(ODS) process for gasoline was carried out to use an oxidant(H2O2) over the D072 resin catalyst.The reaction conditions including the temperature,the amounts of oxidant and the reaction time were studied and discussed.The experimental results show that a maximum sulfur compounds removal of 75% is obtained in the presence of H2O2 with an O/S molar ratio of 17 at room temperature(RT) and atmospheric pressure,which can make a simple and cheap process.The possible mechanism was also disscussed in the study.
