ABSTRACT:
The instant invention relates to a method for preparing a hydrotreating catalyst having improved hydrodenitrification activity by impregnating an alumina supported Group VIB/Group VIII hydrogenating catalyst with a liquid form of a silicon compound having the general formula ##STR1## wherein U, V, W, X, Y, and Z can individually be --R, --OR, --Cl, --Br, --SiH.sub.3, --COOR, --SiH.sub.n Cl.sub.m, R being either hydrogen, or an alkyl, cycloalkyl, aromatic, alkyl aromatic, alkylcycloalkyl radical having from 1 to 30 carbon atoms, "n" and "m" being whole numbers in the range of from 1 to 3 and "a" being a whole number in the range of from 0 to 80, in an amount sufficient to deposit from about 2 to about 8 percent by weight of the total catalyst of Si, and subsequently calcining said impregnated catalyst at a temperature ranging from about 300.degree. C. to about 600.degree. C. in an oxidizing atmosphere.
