    摘要: 본발명은촉매지지체의구조변화를이용하여효율을향상시킨촉매에관한것이다. 본발명은촉매활성입자, 및촉매활성입자를지지하며표면곡률을가지는촉매지지체입자를포함하는것을특징으로한다. 본발명에의하면촉매지지체의화학적특성을변경하지아니하면서도, 촉매지지체의구조를비표면적이높은기하학적인모양으로변형시킴으로써촉매지지체위에분산되는촉매활성입자의분산도를높게유지하고, 분산된촉매활성입자가구조적으로움직이기힘든상태를유지하여, 촉매의성능을향상시킬수 있다.

    摘要: A hydrocracking catalyst contg. Ni and W with Ni/Ni+W atm. ratio of 0.1-0.3 is prepd. and used. Thus, a catalyst prepd. by impregnation of Al2O3 with aq. Ni(NO3)2 and (NH4)2WO4 having a 0.20:1 Ni/Ni+W atm. ratio was used in the hydrocracking of a vacuum gas oil at 1500 psig, 775↿F, and liqspace velocity 1-4h-1. The relative activity was 100 times the ratio of the liq. space velocity required to give a product effluent of which 60 vol. % distd. at 650↿F. The activity is then to be 100 for the std. catalyst.
