Does the catalyst in the cement plant have metal?

Catalysts in cement plants usually do not contain metals. The traditional catalyst in cement plant is mainly denitration catalyst, and its main components are activated carbon, graphite, activated alumina, aluminum-rich borate and other substances, all of which are inorganic non-metallic materials. At present, some metal elements, such as chromium, molybdenum, vanadium and so on. , may be added to some new catalysts to further improve the denitrification efficiency, but the content of these metal elements is very small, usually used in the form of compounds, which will not affect the factory environment and workers' health. It is worth noting that the catalyst should be tested and replaced regularly during use to ensure its effectiveness and safety.
