Catalyst for preparing phosgene and method for preparing phosgene using the same |
| abstract |
The present invention relates to a catalyst for preparing phosgene and a method for preparing phosgene using the catalyst. Said method comprises: modifying the surface of an activated carbon coating/foamed silicon carbide structural catalyst using an alkali metal salt; filling the catalysts having different thickness of the activated carbon coating and different amount of the alkali metal salt in different sections in the axial direction of the multi-tubular reactor of the fixed bed, and preparing phosgene using Cl 2 and CO. The radial and axial temperature difference of the catalyst bed is lowered by using the alkali metal salt-modified activated carbon coating/foamed silicon carbide structural catalyst and by segmental filling, so that high temperature of tube wall is obtained in the case of a larger tube diameter, and high quality of steam is obtained stably. |
