Abstract

The invention relates to a tourmalinite-containing composite methane catalyst. The composite methane catalyst is prepared by compounding of a methane catalyst and tourmalinite, and the mass ratio of tourmalinite to the methane catalyst is 1:50-3:10. The methane catalyst contains a perovskite type methane catalyst, a hexaaluminate type methane catalyst or a metal oxide methane catalyst. According to the invention, the refined mineral material tourmalinite is used in the methane catalyst such that methane gas can be effectively and greatly activated, combustion efficiency and methane combustion rate are raised, production cost is low and the preparation technology is simple. The rare earth tourmalinite composite methane catalysis material provided by the invention can be widely applied in fields of catalytic combustion, industrial organic exhaust-gas treatment, automobile tail gas purification and the like, is of important and active significance for energy saving and emission reduction and reasonable usage of energy, and can bring to the nation with good economic benefit and social benefit.

Description

technical field

[0001] The invention belongs to the field of environmental protection materials, and is a mineral composite catalyst used for natural gas vehicle tail gas, industrial waste gas and air purification. The spontaneous electrical polarity of tourmaline is used to regulate the preparation process of the methane catalyst, which can solve the problem that the methane catalyst is prone to agglomeration during preparation. , the problem of the decrease of the specific surface area; in addition, the infrared radiation characteristics of tourmaline are used to effectively activate methane gas, reduce the light-off temperature of methane, and improve the catalytic activity of the catalyst. Background technique

[0002] Methane is the most stable hydrocarbon, it is usually difficult to activate or oxidize, the combustion temperature is high, and a large amount of NO will be produced during the combustion reaction x , water vapor, and natural gas contains a small amount of...
