METHOD OF OXYDEHYDROGENATION OF HYDROCARBON

摘要

PROBLEM TO BE SOLVED: To provide a method for carrying out the oxydehydrogenation of a hydrocarbon in high yield. SOLUTION: This method of the oxydehydrogenation of the hydrocarbon is characterized in that the oxydehydrogenation reaction is carried out while feeding a raw material containing the hydrocarbon and an oxygen-containing gas to the first layer of a reactor in which an oxydehydrogenation catalyst is dividedly packed so as to form plural layers in the progressing direction of the raw material gas, and supplying the oxygen in the amount corresponding to at least a part of the amount consumed at the previous layer to each layer from the second layer of the catalyst, or feeding the raw material gas to the first step reactor of the plural step reactors having the dividedly packed oxydehydrogenation catalyst and arranged in series, and supplying the oxygen in the amount corresponding to at least a part of the oxygen consumed in the reactor at the previous step, to each reactor at the second or the later step.
