A method for selectively chemically reducing COto form CO includes providing a catalyst, and contacting Hand COwith the catalyst to chemically reduce COto form CO. The catalyst includes a metal oxide having a chemical formula of FeCoMnO, in which 0.7≤x≤0.95, 0.01≤y≤0.25, and z is an oxidation coordination number.

Catalyst for selectively chemically reducing COto form CO

A catalyst composition for hydrogenating 4,4′-methylenedianiline derivatives is provided. The catalyst composition includes a carrier including aluminum oxide and magnesium oxide, a rhodium-ruthenium active layer loaded on the surface of the carrier, and a solvent including an organic amine. The weight percentage of magnesium oxide in the carrier is between 12% and 30%. A method for preparing 4,4′-methylene bis(cyclohexylamine) derivatives using the catalyst composition is also provided.

Method for selectively chemically reducing COto form CO

Disclosed is a catalyst for hydrogenation of 4,4'-methylenedianiline (MDA), including a support, a magnesium-aluminum oxide layer covering the support, and a rhodium-ruthenium active layer loaded on the magnesium-aluminum oxide layer, wherein the rhodium and the ruthenium of the rhodium-ruthenium active layer have a weight ratio of 40:60 to 10:90. The hydrogenation catalyst can be collocated with hydrogen for hydrogenation of the MDA to form bis(para-amino cyclohexyl) methane (PACM), and the PACM contains 0 mol % to 25 mol % of (t,t)-isomer.
