摘 要:采用酸性的Nb_(2)O_(5)和高比表面的γ-Al_(2)O_(3)制备了复合载体Nb_(2)O_(5)-γ-Al_(2)O_(3),并负载Ni-B非晶态合金得到负载型催化剂。通过对催化剂的酸性及酸强度测定,考察了复合载体对催化活性的影响。结果表明,当载体中Nb_(2)O_(5)含量为30%时,因适量B酸和L酸的协同作用使得催化剂的活性最高,达到78.4%。Composite support Nb_(2)O_(5)-γ-Al_(2)O_(3) was prepared using acidic Nb_(2)O_(5) andγ-Al_(2)O_(3) with high specific surface,and then supported catalysts were obtained by loading Ni-B amorphous alloy.The effect of the composite support on the catalytic activity was investigated by measuring the acidity and acid strength of the catalyst.When the content of Nb_(2)O_(5) in the support is 30%,the synergistic effect of proper amount of B acid and L acid made the catalyst have the highest activity,reaching 78.4%.
