Title:
CATALYST FOR REMOVING BY REDUCTION NITROGEN OXIDE IN EXHAUST GAS WITH AMMONIA, PREPARING METHOD OF THE CATALYST, METHOD FOR REMOVING NITROGEN OXIDE IN EXHAUST GAS AND CLEANING METHOD OF SINTERING EXHAUST GAS
Document Type and Number:
Japanese Patent JP2006212548
Kind Code:
A
Abstract:
To provide an inexpensive and high-performance method for preparing a catalyst removing by reduction nitrogen oxides in an exhaust gas with ammonia, a method for removing by reduction the nitrogen oxides in the exhaust gas with ammonia using the catalyst, and a cleaning method of a sintering exhaust gas.
After adjusting sizes of soil having a water contained iron oxide as a main component the catalyst is prepared by molding. The nitrogen oxides in the exhaust gas are removed by reduction by bringing the exhaust gas loaded with ammonia into contact with the prepared catalyst.
