Time:2017-09-20

Rare earth in addition to the manufacture of petroleum cracking catalyst, widely used in many chemical reactions, such as rare earth oxides LaO3, Nd2O3 and Sm2O3 for cyclohexane dehydrogenation benzene, with LnCoO3 instead of platinum catalytic oxidation of nitric acid nitric acid. And in the synthesis of isoprene rubber, butadiene rubber production as a catalyst. Automobile exhaust gas need to CH, CO oxidation, NOX reduction treatment to address the current urban air pollution problems. Rare earth element is the main raw material for automobile exhaust gas purification catalyst. Rare earth catalysis is also used in paint drying, plastic stabilizers and rare earth polymer materials and many other fields.
