active support catalyst

The active component can be well adsorbed on the support(D3520), on which the lifetime of the catalyst is prolonged.

D3520载体对活性组份具有良好的吸附性能，延长了催化剂的使用寿命。

The high purity, high surface area, large pore volume and proper pore structure of active carbon as a support for ruthenium catalyst usually lead to high catalytic activity for ammonia synthesis.

具有高纯度、高比表面、大孔容及合理孔分布的活性炭载体有利于活性组分有效均匀的分散，制备出高活性的氨合成钌催化剂。

However, the development of metallic monolithic catalyst is prevented by a low activity and a poor adhesion of the active component with the support.

制备出具有高活性和粘附稳定性的金属负载整体型催化剂是本论文的目标。
