纳米自组装制备的二次纳米自组装氧化铝载体具有大孔容、较高比表面积、低堆积密度的特点，采用此载体，第三次纳米自组装合成的大孔主客体催化剂的脱硫、脱氮和芳烃饱和率分别达到66．7％、34．6％和77．1％，单位体积活性金属有效利用率高。对催化剂高活性的特点，根据共振场内敛性原理的双共振-双进动谐振运动模型，提出了共振吸附-氢溢流机理，解释M o、Ni等过渡金属元素作为催化剂活性组分时的催化机理，特别是大孔主客体催化剂高加氢活性的机理。

Secondary nano self-assembly alumina was prepared by nano self-assembly owns the properties of large pore volume ,high specific surface area and low bulk density .Adopt this carrier ,a macroporous host-guest catalyst was prepared by third nano self-assembly .The desulfurization ,denitrification and aromatics saturation rate of the catalyst could be as much as 66.7% ,34 .6% and 77 .1% ,which showed a high performance of active metal per unit volume .In order to explain the high activity of macroporous host-guest catalyst ,a resonance absorption hydrogen spillover mechanism was proposed in this paper . Based on the double resonance-double precession-resonance movement model of introverted principle of the resonance field ,it explains the high hydrogenation activity of active components (transition metal elements as Mo ,Ni etc .) well ,especially for macroporous host-guest catalyst .
