Abstract

The invention discloses a preparation method of a wire mesh denitration catalyst for selective catalytic reduction (SCR), and relates to the technical field of environmentally-friendly catalytic materials. The method is proposed based on the problem that an active component in a current denitration catalyst is not easily supported on the surface of a metal material carrier; and the method comprises the following steps: (1) performing etching on a carrier; and (2) performing impregnation on the carrier, performing drying, and performing calcination. The invention also provides the wire mesh denitration catalyst for the SCR prepared by the above preparation method. The method provided by the invention has the beneficial effects that the wire mesh denitration catalyst for the SCR prepared bythe method has good denitration performance under the temperature condition of 70-120 DEG C, and the activity at 80 DEG C reaches 80% or more.

Description

technical field

[0001] The invention relates to the technical field of environment-friendly catalytic materials, in particular to a method for preparing a wire mesh SCR denitration catalyst and the prepared catalyst. Background technique

[0002] With the continuous growth of energy consumption, my country's air pollution prevention and control will face a more severe situation. Among them, nitrogen oxides (NO X ) as one of the main air pollutants, usually including NO, NO 2 , and N 2 O, etc., they mainly come from the exhaust gas of motor vehicles, thermal power station exhaust gas, ship exhaust gas and high-temperature combustion exhaust gas of fossil fuels in other industries. Currently, the most effective NO X Removal technology, still popular Selective Catalyst Reduction (SCR) technology.

[0003] At present, flue gas denitrification catalysts widely used commercially are mainly V~Ti catalysts, which have good denitrification performance at 300-400°C. However, thi...
