Ni/TiO2 hydrogenation catalytic converter

摘要

And at least selected from Group 5 to 11 group of the periodic table of the elements and optionally at least one other metal and is selected from Si and Ni, Zr, Hf, alkaline earth metals, Y, La, a Ce By coprecipitated on the carrier, and passivated in some cases reduction and subsequently dried, and calcined, is changed to a nickel containing catalyst _- 2 TiO finely divided from a solution containing a metal salt of the corresponding, doped metal single can be obtained, 2 TiO _- catalyst containing nickel on a support. The catalyst is used for the hydrogenation of nitro aromatic compounds in particular.
