Process for hydrotreating heavy hydrocarbon oil

Patent ·
OSTI ID:5538276
; ; ;
This invention relates to a process for continuously converting a heavy oil into an asphaltene-metal-free oil by hydrotreating said heavy oil to crack asphaltenes selectively and remove heavy metals such as vanadium and nickel from said heavy oil simultaneously, separating the liquid products into a light fraction of an asphaltene-free and metal-free oil and a heavy fraction of an asphaltene and heavy metal-containing oil, recovering said light fraction as a product, and recycling said heavy fraction to said hydrotreating step.
