Abstract:
1. A process of hydrotreating a heavy hydrocarbon oil, comprising the steps of: distilling a heavy crude oil with an API degree of 30 or less to obtain a light fraction distillate of the heavy crude oil and a heavy hydrocarbon oil distilled residue of the heavy crude oil; distilling a light crude oil with an API degree of 35 or greater to obtain a light fraction distillate of the light crude oil and a heavy hydrocarbon oil distilled residue of the light crude oil; mixing 100 parts by volume of the heavy hydrocarbon oil distilled residue of the heavy crude oil and 30 to 1000 parts by volume of the heavy hydrocarbon oil distilled residue of the light crude oil to obtain a mixed oil; and hydrotreating the mixed oil to produce a low sulfur heavy fuel oil with a sulfur content of 1 percent by mass or less.
