摘要:
Catalyst for hydrogenation of 1,3-cyclobutanediketone compound is provided, which includes a support and VIIIB group transition metal loaded thereon. The support includes a first oxide powder with a surface wrapped by a second oxide. The first oxide includes silicon oxide, aluminum oxide, zirconium oxide, titanium oxide, zinc oxide, or a combination thereof. The second oxide has a composition of MxAl(1-x)O(3-x)/2, M is alkaline earth metal, and x is from 0.3 to 0.7.

摘要:
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.
