There is a growing need for effective heavy oil upgrading processes as the demand for high value petroleum products is mounting and the sources of crude oil are becoming more and more unconventional. Upgrading processes involve converting heavy fractions into light fractions, distillates, with higher hydrogen to carbon ratio and removing heteroatoms, which ultimately improve the combustion characteristics and reduce the environmental impact of fuel utilization. Major upgrading processes fall under hydrocracking and/or thermalcracking, which may involve catalysts. Catalytic upgrading is the most promising technology for the conversion of heavy oils into lighter products. The catalyst reduces the severity of the upgrading reactions and enhances the selectivity by reducing the activation energy barrier of given reactions. Heavy oil is cracked and hydrogenated by both catalytic and thermal reactions to produce more valuable distillates. Typical catalysts used in residue upgrading are oxides of molybdenum, cobalt, nickel and/or tungsten supported on a matrix of alumina and/or silica.

随着对高价值石油产品的需求不断增加以及原油来源变得越来越非常规，对有效的重油改质方法的需求日益增长。改质工艺涉及将重馏分转化为轻馏分、馏出物，具有更高的氢碳比并去除杂原子，这最终改善了燃烧特性并减少了燃料利用对环境的影响。主要的改质工艺属于加氢裂化和/或热裂化，这可能涉及催化剂。催化改质是重油转化为轻质产品的最有前途的技术。该催化剂通过降低给定反应的活化能势垒来降低改质反应的剧烈程度并提高选择性。重油通过催化和热反应裂化和加氢以产生更有价值的馏分。用于残渣提质的典型催化剂是负载在氧化铝和/或二氧化硅基质上的钼、钴、镍和/或钨的氧化物。
