摘要 |
An object of the present invention is to provide a method for vapor phase catalytic oxidation which is almost free of variations in reaction states in respective reaction tubes of the fixed bed multi-tube heat-exchanger type reactor. <??>Provided is a method for vapor phase catalytic oxidation for obtaining a reaction product gas by using a fixed bed multi-tube heat-exchanger type reactor provided with a plurality of reaction tubes and by feeding a raw material gas inside the reaction tubes packed with a catalyst, wherein the method comprises: adjusting pressure losses of the respective reaction tubes so that the pressure losses of the respective reaction tubes after catalyst packing is within +/-20% of an average pressure loss of the reaction tubes by: packing an inert substance at a raw material gas inlet portion of the reaction tubes or removing and re-packing the catalyst packed, for a reaction tube having a pressure loss lower than the average pressure loss of the reaction tubes; and removing and re-packing the catalyst packed, for a reaction tube having a pressure loss higher than the average pressure loss of the reaction tubes. <IMAGE> |
