Abstract:
A process for treating a heavy hydrocarbon oil feed comprising:a) forming a slurry which includes a heavy hydrocarbon oil and a hydroprocessing catalyst based on a catalyst support selected from the group consisting of alumina, silica-alumina, silica, titania, and magnesia; b) introducing said slurry into a reaction zone in the presence of hydrogen; and, c) subjecting the slurry to upgrading conditions to provide a hydrocarbon oil product having an improved API gravity and a lower acid number wherein the concentration of the catalyst in the slurry is substantially the same as the concentration of the catalyst in the slurry present in the reactor and in the hydrocarbon oil product and wherein the concentration of the hydroprocessing catalyst present in the slurry is between about 0.02 to about 2.0 percent by weight.
