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.

Claim (Index 10):
A preparation method of the catalyst according to  claim 1  comprising the following steps:\n 1) impregnating the carrier with metal solutions or metal melts to obtain a catalyst precursor; \n 2) drying and calcinating the catalyst precursor to obtain the catalyst; \n wherein the metal solutions are aqueous solutions of metal salts or aqueous solutions of metal salt complexes, the metal melts are molten metal salts, and the metals include active metals Ni, Cu and Pd.
