Catalyst applied to amination of polyether polyol, preparation method thereof and method for preparing polyether amine by using catalyst

The invention relates to a catalyst applied to amination of polyether polyol, a preparation method thereof and a method for preparing polyether amine by using the catalyst. The catalyst comprises active components and a carrier, wherein the active components comprise Ni, Cu and Pd. The preparation method of the catalyst comprises the following steps: dipping the carrier with a metal solution or molten metal to obtain a catalyst precursor; drying and roasting the catalyst precursor to obtain the catalyst. The active component Pd is introduced into the catalyst, so that the selectivity of the amination catalyst on expected amine products and the conversion rate of the raw material are obviously improved.
