Abstract

The invention discloses a denitration catalyst less prone to pulverization. The denitration catalyst less prone to the pulverization is prepared from, by weight, 50-70 parts of titanium dioxide, 8-15 parts of molybdenum trioxide, 4-9 parts of ferric oxide, 3-7 parts of copper oxide, 1-5 parts of aluminum oxide, 1-7 parts of silicon dioxide, 2-10 parts of vanadium pentoxide, 2-7 parts of bamboo fiber, 3-7 parts of glass fiber, 2-7 parts of carbon fiber and 1-6 parts of stearic acid. The denitration catalyst less prone to pulverization is high in intensity, long in service life and less prone to the pulverization.

Description

technical field [0001] The invention relates to the field of denitrification digestion, in particular to a denitrification catalyst that is not easy to pulverize. Background technique [0002] Denitrification catalyst generally refers to the catalyst (Catalyst) used in the SCR (selective catalytic reduction) denitrification system of the power plant. In the SCR reaction, the substance that promotes the chemical reaction of the reducing agent selectively with the nitrogen oxides in the flue gas at a certain temperature . [0003] Currently, there are three types of denitrification catalysts on the market: plate type, honeycomb type and corrugated plate type. Although the catalytic efficiency has been improved, there are still defects such as low strength, easy pulverization, and short service life, which need to be improved. Contents of the invention [0004] The purpose of the present invention is to solve the defects of easy pulverization and short service life in the pr...
