Abstract
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 (hereinafter briefly referred to as 'removal of metals'), 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 (hereinafter referred to as a 'heavy fraction'), recovering said light fraction as a product, and recycling said heavy fraction to said hydrotreating step.
