Abstract
This invention relates to the cleaning of flue gas released from various combustion processes, particularly a surface deposition NH—SCR honeycomb catalyst and its preparation method. The catalyst is composed of framework material, TiO, VOand WO, wherein the framework material is composed of clay, coal ash, mineral waste residue or their mixture. The mass fractions for framework material, TiO, VO, and WOare 60 wt. % to 80 wt. %, 13 wt. % to 33 wt. %, 1 wt. % to 5 wt. %, and 0.1 wt. % to 2 wt. %, respectively. The nano VO—WO—TiOparticles were deposited on the surface of particle pore or honeycomb, and the performance of the catalyst could be greatly improved.
