摘要
渣油轻质化是当今世界各国石油加工的主要课题之一，它已成为炼油工业发展的必然趋势。我国渣油的主要特点是：Ｈ／Ｃ原子比属中等，芳碳率比较小，因此轻质化的潜力较大；沥青质含量一般较低，而胶质含量高，且在胶质中集中了绝大部分的氮和镍，这是渣油加工路线选择时必须注意的问题。应根据不同渣油的特点，选择经济合理的加工技术路线。目前，重油催化裂化、渣油加氢处理、延迟焦化和组合工艺已成为渣油加工的主要手段。
Residuum upgrading is one of the main subjects of world petroleum processing, and has become the inexorable trend of the development of petroleum refining. The main characteristics of Chinese residues are medium-sized H/C atom ratio, low fA, high resin content, relatively low asphaltene content, and most of the nitrogen and nickel are concentrated in resin. In consideration of the above characteristics, the economic and reasonable technologies should be chosen for the residuum processing, such as heavy oil catalytic cracking, vacuum residue hydrotreating, delayed coking, as well as the combination of the processing technologies.
