Title:
LOW TEMPERATURE DENITRATION CATALYST AND ITS PRODUCTION AND LOW TEMPERATURE DENITRATION METHOD
Document Type and Number:
Japanese Patent JP3843520
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To denitrate exhaust gas at a relatively low temp.
SOLUTION: In a low temp. denitration catalyst in which at least one kind metal oxide amount Mn, Fe, Co and Ni is deposited on an activated carbon fiber, the activated carbon fiber is impregnated with an aq. soln. of at least one kind metallic salt amount Mn, Fe, Co and Ni, and after vacuuming the fiber, the fiber is dried, then the fiber is heated at 200-300°C in an oxidative atmosphere to convert the metallic salt to the metal oxide. And the low temp. denitration is executed by allowing a gas containing nitrogen oxide to contact with this catalyst in the presence of a reducing agent.
