What are rare earth catalytic materials

Rare earth catalytic materials are mainly divided into vehicle exhaust purification catalyst and petroleum cracking catalyst. The main rare earth materials used are the mixture of cerium oxide, praseodymium oxide and lanthanum oxide, among which cerium oxide is the key component.

Vehicle exhaust purification catalyst is mainly used to purify the exhaust gas from vehicles, among which rare-earth based three-way catalyst is the most widely used, which is favored for its low price, good thermal stability, high activity, long service life and other characteristics.

Molecular sieve rare earth catalytic materials are used in the petroleum cracking catalyst, which can greatly improve the conversion rate of crude oil cracking and increase the yield of gasoline and diesel oil. The use of rare earth MOLECULAR sieve catalyst for petroleum cracking has the advantages of large crude oil handling capacity, high yield of light oil, high product quality, high activity, low coking rate, low catalyst loss and good selectivity.

Rare earth Catalytic Materials: Applications in Environmental protection Content introduction: rare earth elements play an important role in a variety of catalytic materials due to their unique catalytic properties. "Rare EARTH Catalytic MATERIALS: Applications in ENVIRONMENTAL PROTECTION" systematically describes the application of rare earth catalytic materials in environmental protection. The rare EARTH ELEMENTS AND THEIR ENVIRONMENTAL CHEMICAL BEHAVIORS WERE BRIEFLY INTRODUCED, AND THE ACTION MECHANISM of rare EARTH CATALYSTS WAS DISCUSSED. The wide applications of rare earth catalysts in photocatalytic environmental purification, automobile exhaust purification, industrial waste gas and industrial wastewater treatment, and catalytic combustion were highlighted. "Rare Earth Catalytic Materials: Application in Environmental Protection" can be used as a reference for scientific and technical personnel engaged in environmental science, development and application of rare earth resources, chemical engineering and process, applied chemistry, material science and engineering, etc. It can also be used as a textbook and teaching reference book for undergraduate and graduate students majoring in environmental science, applied chemistry, chemical engineering and process, rare earth chemistry and related majors in universities and colleges.
