【Abstract】 A series of HxKaM0.76Mo11PVAs0.68Oy heteropoly compound catalytic membranes supported over porous titanium plate were prepared by impregnation. The catalytic oxydehydrogenation of cyclohexane was carried out in a self-made membrane reactor. The effects of the temperature and the proportion of N 2 and O 2 were studied. The result showed that the addition of Fe3+, Bi3+, K+ is very useful for increasing the catalytic activity, especially the H xK 0.37Bi 0.76Mo 11VPAs 0.68O y catalyst has the highest activity at 300℃ and VN 2:VO 2=3:2. The product rate of the catalytic oxydehydrogenation of cyclohexane reaches 25.8%.更多还原
