Abstract
In a process for upgrading heavy asphaltenic oil, a feed slurry of a heavy asphaltenic oil and less than 10 ppm of molybdenum, e.g. molybdenum naphthenate, is contacted with a hydrogen-rich gas in a hydroconversion zone at hydrocracking conditions to convert at least a portion of said heavy oil to lower boiling products. This is achieved with minimum coke formation under moderate processing conditions.
