Methods for long-term operation of the gas phase partial oxidation by heterogeneous catalysis from acrolein to acrylic acid

摘要

Before the temperature rise is 8 ℃ A method for the long-term operation of the gas phase partial oxidation by heterogeneous catalysis of acrolein to acrylic acid, and then increased with time the temperature of the fixed catalyst bed It is aimed to interrupt the partial oxidation is passed through the fixed catalyst bed the oxygen-containing gas.
