Abstract
This invention discloses a preparation method of a hydrocracking catalyst. According to the method, a new functional group is modified through chemical bonds on the surface of a traditionally prepared inorganic carrier, and a VIB group metal element and a VIIIB metal element are then loaded on the carrier to prepare the hydrocracking catalyst. The hydrocracking catalyst prepared according to the invention has a higher diesel liquid yield.
