1. A method of producing a Ni/Mo hydrodesulfurization catalyst, the method comprising:
dissolving an Ni(II) salt in water to form a first solution;
dissolving an Mo(VI) salt in water to form a second solution;
granulating and pyrolyzing waste tires to form a first activated carbon, adding a first mixture comprising ethanol, water and TiCl4 to a second mixture comprising water and the first activated carbon to form a third mixture, then adding ammonia to the third mixture to form a gel, then drying the gel to form a dry Ti-activated carbon,
adding the dry Ti-activated carbon to the first and second solutions to form a fourth mixture;
drying the fourth mixture at a temperature of 50-150° C. thereby producing a solid; then
calcining the solid at a temperature of 160-500° C. to form the Ni/Mo hydrodesulfurization catalyst,
wherein:
the Ni/Mo hydrodesulfurization catalyst comprises nickel and molybdenum disposed on the Ti-activated carbon;
the Ni/Mo hydrodesulfurization catalyst is mesoporous with a BET surface area of 250-500 m2/g, an average pore diameter of 4-10 nm, and a pore volume of 0.2-3 cm3/g; and
the Mo(VI) salt is ammonium heptamolybdate (VI).
