  • Fabrication method of zeolite honeycomb type catalyst for reducing nitrogen oxide
    Patent number: 8178063
    Abstract: The present invention relates to conversion of exhaust gas containing nitrogen oxide (NOx) such as NO, NO2 and N2O into N2 and H2O through catalytic reaction with injection of a reducing agent such as ammonia and urea. A fabrication method of zeolite honeycomb type catalyst for reducing nitrogen oxide of the present invention includes: (a) obtaining an inorganic binder by mixing and uniformly peptizing pseudo-boehmite, distilled water and a pH adjuster; (b) obtaining a paste by mixing and kneading zeolite, the inorganic binder, an organic binder and distilled water; (c) extruding the paste into an extrudate having a through pore of a regular structure; and (d) drying and heat treating the extrudate.
    Type: Grant
