A palm kernel oil hydrodeoxygenation catalyst and a preparation method thereof

Abstract

This invention discloses a palm kernel oil hydrodeoxygenation catalyst and its preparation method, belonging to the field of bioenergy catalysis technology. The catalyst includes a support and an active component loaded on the support; the support is modified alumina, obtained by rare earth element doping modification of alumina; the active component is a nickel-molybdenum composite active component, with nickel loading of 3%-8%, molybdenum loading of 5%-12%, and rare earth element doping of 0.5%-3% based on 100% of the total catalyst mass. This invention, through a fully innovative chain design of "rare earth doping modified support - precise ratio of nickel and molybdenum active components - phosphorus-co-catalytic synergy - stepwise controllable preparation - mild application conditions," forms a highly efficient catalytic system suitable for palm kernel oil hydrodeoxygenation to biodiesel production, possessing four core advantages: superior performance, strong stability, economical process, and industrial adaptability.
