Process for manufacturing a carbonaceous catalyst for the reduction of nitrogen oxides in exhaust gases |
摘要 |
A process is disclosed for treating carbonaceous catalyst with a gaseous halogen or a gaseous halogen compound to increase the catalytic activity and prolong the useful life of the catalyst. The treatment of the catalyst is conducted at temperatures above about 150 degrees C., preferably with the use of an inert gas, which inert gas is flowed through the carbonaceous material, and which inert gas carries the gaseous halogen or the gaseous halogen compound to the carbonaceous material.
