Low the molybdenum - vanadium catalytic converter for temperature choice oxidation of propylene, the production manner and the element Mo which

摘要

(57) Abstract It consists of the molybdenum, vanadium, palladium, lanthanum, niobium and X, (however, as for X, it is the copper and/or the chrome,) it brings the high yield of acrylic acid and acrolein without accompanying the formation of the by-product like CO at the time of low temperature oxidizing of the propylene with the molecular oxygen content gas, mixed metallic oxide catalyst system.
