Heavy oil upgrading is an important topic. So a recent article authored by
people affiliated with King Fahd University of
Petroleum & Minerals might be something you would want to read.

Abstract
Unconventional feedstocks, such as heavy vacuum residue (VR), have become potential candidates that could be positively exploited to meet the increasing demand of high-value transportation fuels in view of the growing scarcity in other energy sources. However, such feeds contain extremely high molecular weight species besides many impurities of heteroatom-containing organic compounds that lead to quick fouling, poisoning and deactivation of catalysts. This causes significant pressure drop during the conventional hydrocracking in ebullated- or fixed-bed reactors. In contrast, slurry-phase hydrocracking has the ability to overcome these drawbacks through the enhancement of hydrogenation reactions in the presence of the dispersed catalysts. Slurry-phase processing is a resilient technology, which employs catalysts that are generally categorized as heterogeneous solid supported catalysts and homogeneously dispersed catalysts. The dispersed catalysts are classified into water or oil-soluble types and fine powders. Soluble dispersed catalysts show higher catalytic activity compared to finely powdered catalysts, due to in situ formation of infinitesimally minute active metal sites at high surface area-to-volume ratios. Recent technologies and studies on heavy oil upgrading that implement the dispersed catalysts have been reviewed. Studies using a combination of two-phase catalysts have also been included.
