Denitrification and VOC removing catalyst

Abstract

The invention relates to a denitrification and VOC removing catalyst, and belongs to the field of environmental protection catalysts. According to the present invention, the Mo-V-W / TiO2-Al2O3 system is formed among various components of the catalyst, such that the functions of denitrification and VOC removing can be concurrently achieved under the effect of the active components such as Mo, V and W and the carrier TiO2-Al2O3, the structure of the tail gas filtration discharging equipment can be effectively simplified, and the environmental protection cost can be reduced; and the denitrification and VOC removing catalyst has the high dust interference resistance, and can provide the maximum filtration performance on the basis of no requirement of the frequent stopping-dust cleaning, such that the catalyst has advantages of uniform aging speed, strong filtration ability, and long service life.

Description

technical field [0001] The invention relates to a catalyst for denitrification and VOC removal and a preparation method thereof, belonging to the field of catalysts for filtering polluted gases. Background technique [0002] With the development of my country's economy, my country's coal energy consumption and the number of motor vehicles have increased significantly, resulting in a rapid increase in the content of various pollutants in the air. After decades of hard work, my country has achieved some success in controlling dust and sulfur dioxide pollution, but the pollution of VOC and nitrogen oxides has not yet been controlled. Therefore, how to effectively control the emission of VOC and nitrogen oxides has become the focus of the current environmental protection field. [0003] Traditional catalysts can only filter VOC or nitrogen oxides in one direction, which leads to complex equipment structure and increased production costs when filtering mixed flue gas. Moreover,...

Moreover, traditional catalysts rely on honeycomb catalysts for filtering operations. This catalyst has a simple structure. However, once large particles enter the catalyst, the entire honeycomb strip will be blocked and cannot perform normal filtration reactions.
