Vanadium pentoxide catalytic membrane reactor for partial oxidation of 1-butene

Abstract The vanadium pentoxide catalytic membrane reactor was prepared by coating its sol inside the Vycor® tube membrane. After heat treatment of the prepared membrane, the [010] planes of vanadium pentoxide layer were grown largely which contributes to partial oxidation reaction of 1-butene to maleic anhydride. The partial oxidation of 1-butene to maleic anhydride was carried out in the catalytic membrane reactor. The maximum selectivity of 95% was obtained at 350°C when the surface velocity was 500cm/h. And at this condition, oxygen permeability was almost four times higher than the reaction had not occurred.

SELECTIVE OXIDATION USING CATALYST ELECTRODES SUPPORTED ON SOLID ELECTROLYTE

The major oxygenated products of the selective oxidation of 1-butene by using a catalyst electrode were maleic anhydride on V2O5/YSZ/Ag and butadiene on MoO3−Bi2O3−Ag/YSZ/Ag. Their selectivities were enhanced as compared with the non-electrochemical system.
