PROCESS FOR CATALYTIC VAPOR PHASE OXIDATION

摘要

The cell which contains a lot of tube bundle filled with an oxidation catalyst is devided into at least two elecric heat medium supply section. The tubes which pass through the cell hole made of poure shielding plate are not directly contacted with the shielding plate by separating from cell hole by 0.2-5mm. The temp. difference between each electric heat medium section divided by the plate is controlled within 0-100≦̸C. The raw gases are oxidated by the gas reaction in the tube.
