1. A catalyst system comprising:
an alumina support;
a promoter component containing phosphorous in an amount of 1 wt % impregnated in the alumina support; and
an active metal component comprising nickel, cobalt, and molybdenum impregnated in the alumina support in an amount of 10 wt %;
wherein a molar mass of molybdenum is greater than the combined molar mass of cobalt and nickel, wherein a mole ratio of nickel:cobalt:molybdenum is 1:1:3,
wherein the promoter component is chemically bonded to the alumina support in the form of aluminum phosphide, and
wherein the promoter component is chemically bonded to the active metal component in the form of metal phosphides.
