  • Process for dispersing transition metal catalytic particles in heavy oil
    Patent number: 5916432
    Abstract: A transition metal salt, preferably ammonium heptamolybdate, is dissolved in water to provide a solution containing the dispersed catalyst precursor. The solution is atomized by passing it through an atomizing nozzle submerged in hot oil. The minute atomized droplets are delivered into the hot oil and the water is flashed to form steam bubbles. The precursor forms catalytic particles distributed in the oil.
