A method for the catalytic gas-phase oxidation of hydrocarbons and catalysis reaction before the direction of

摘要

The present invention relates to a process for the catalytic gas-phase oxidation of hydrocarbons, which comprises: a) providing a catalysis reaction direction with a cooling medium to be cooled reaction space between a gas inlet and a gas outlet, and b) directing a hydrocarbon - reaction mixture containing through the reaction chamber in a gas flow direction, characterized in that the coolant with a in the gas flow direction is provided a rising temperature profile; and a corresponding catalysis reaction before the direction of.
