Abstract: A supported catalyst used for synthesizing a polyether amine, and a manufacturing method of the catalyst. The catalyst comprises: a porous oxide as a support; Ni, Cu, Pd, and Rh as active components; and one or more of any of Zr, Cr, Mo, Fe, Zn, Sn, Bi, Ce, La, Hf, Sr, Sb, Mg, Be, Re, Ta, Ti, Sc, Ge and related metals as an auxiliary agent. The catalyst can be used in an amination reaction for a large molecular weight polyether polyol, and is particularly active and selective for an amination reaction of a low molecular weight polyether polyol. The catalyst has a simple and economic manufacturing technique and good potential for future applications.

Abstract: The present invention relates to a catalyst for aminating a polyether polyol and preparation method thereof and a method of preparing a polyetheramine using the catalyst. The catalyst has active components and a carrier. The active components are Ni, Cu, and Pd. The method of preparing the catalyst comprises the following steps: using a metal solution or a metal melt impregnated carrier, obtaining a catalyst precursor; and drying and calcinating the obtained catalyst precursor, so as to obtain a catalyst. By introducing the active component Pd in the catalyst, the present invention clearly improves selectivity of an amination catalyst with respect to a preaminated product, and increases raw material conversion rate.

Abstract: Disclosed is a method for preparing diamino-dicyclohexyl methane (H12MDA) by hydrogenation of diamino-diphenyl methane (MDA). In the process, 4,4?-MDA used as the starting material is firstly hydrogenated to prepare 4,4?-H12MDA. When the activity of the catalyst is reduced, the feed is switched from 4,4?-MDA to the mixture of 2,4?-MDA and 4,4?-MDA, and then when the conversion is stabilized, the feed is switched to 4,4?-MDA again. The deactivated catalyst is activated on line by switching the feed to the mixture of 2,4?-MDA and 4,4?-MDA. 4,4?-H12MDA having the trans-trans isomer content of 16˜24 wt % is produced, and the mixture of 2,4?-H12MDA and 4,4?-H12MDA is also produced, wherein the content of 2,4?-H12MDA in the mixture is 4˜15 wt %.
