The role of ruthenium-based catalysts

As an important catalyst, ruthenium-based catalysts have the advantages of high selectivity, high activity and mild catalytic conditions that other traditional catalysts do not have in the field of gas-solid gas phase catalysis. At present, the active components of ruthenium-based catalysts are ruthenium, ruthenium dioxide or ruthenium trichloride, and the carriers are mainly zeolite, alumina (α type), activated carbon or graphitized carbon, titanium dioxide (rutile type), and a mixture of alumina and titanium dioxide.

There are many preparation methods, mainly precipitation method, ion exchange method, impregnation method and melting method. The ruthenium-based catalysts for the oxidation of hydrogen chloride to chlorine, the ruthenium-based catalysts for the selective hydrogenation of benzene to cyclohexene, the ruthenium-based catalysts for the synthesis of ammonia and the ruthenium-based catalysts for the Fischer-Tropsch synthesis are several important catalysts at present.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/19141.html
