| 摘 要： | 为研究空气等离子体对丙烯的活化作用,在室温和常压下,采用介质阻挡放电法,考察玻璃反应器材质种类及长度对丙烯转化率、环氧丙烷选择性及其他产物分布的影响.实验结果表明:介质阻挡放电法可转化丙烯和空气直接生成环氧丙烷;玻璃反应器材质种类对丙烯环氧化反应有显著影响;在其他条件不变的情况下,随着反应器长度增加,丙烯转化率迅速增加,环氧丙烷、丙醛和丙烯醛等C3类氧化产物的摩尔分数均降低.

| Abstract: | The role of plasma activation was studied in the vapor phase oxidation of propylene using molecular oxygen in air.The plasma was obtained by applying dielectric barrier discharge(DBD) to the mixture of air and propylene at room temperature and atmospheric pressure.The synthesis of PO form's C3H6 and air in DBD plasma was demonstrated and the effect of the composition of glass reactors and the length of reactor on propylene conversion,PO selectivity and products' distribution was observed as well.The results show that the composition of glass reactors has a great effect on propylene epoxidation reaction.With the increase of the length of reactor,the conversion of propylene increases,and the selectivities of C3 partial oxidation products decrease if other conditions kept unchanged. |
