摘要： The present invention relates to conversion of exhaust gas containing nitrogen oxide (NO
x ) such as NO, NO
2 and N
2 O into N
2 and H
2 O 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.
