The trend to cut deeper into the bottom of the barrel to produce additional yields of high-value vacuum gas oil (VGO ) at the expense of low-value residue creates new opportunities and challenges for downstream conversion or upgrading of these heavier feedstocks. The trend also reveals a need for a rational, consistent way of assessing yield and quality of
