    • The invention provides a method of transaminating a reactant with a catalyst composition comprising support and catalyst portions. The support includes an acidic mixed metal oxide including a transitional alumina and a second metal oxide. The transitional alumina can comprise delta or theta alumina, in combination with other transitional phases, or an alpha or gamma alumina. The second metal oxide has a weight percentage less than the weight percentage of alumina. The catalyst portion is 25 weight percent or less of the catalyst composition and is composed of nickel and rhenium. The catalyst portion includes nickel in an amount in the range of 2 to 20 weight percent, based upon total catalyst composition weight, and there is no boron in the catalyst portion. The method provides high activity and selectivity for reactant transamination to a desired product while minimizing the formation of unwanted cyclic products.
    • 本发明提供了一种用包含载体和催化剂部分的催化剂组合物将反应物转氨的方法。 载体包括含有过渡氧化铝和第二金属氧化物的酸性混合金属氧化物。 过渡氧化铝可以包含与其它过渡相结合的δ或θ氧化铝,或α或γ氧化铝。 第二金属氧化物的重量百分比小于氧化铝的重量百分数。 催化剂部分为催化剂组合物的25重量%以下,由镍和铼构成。 催化剂部分包括基于总催化剂组合物重量的2-20重量%范围内的量的镍,并且在催化剂部分中不存在硼。 该方法提供了对期望产物的反应物转氨酸的高活性和选择性,同时使不期望的环状产物的形成最小化。
