Residue catalytic cracking is the main means of residue conversion: in 2005, the processing capacity of China catalytic cracking unit exceeded 93 million tons, including atmospheric residue180 thousand tons and vacuum residue130 thousand tons. Residue catalytic cracking (RFCC) has become an important device for heavy oil conversion. Catalytic cracking is the core technology of converting heavy oil into light distillate oil, but the product quality and technology are severely challenged by environmental protection, so it is necessary to develop new catalytic cracking technology to improve the product quality.
Delayed coking is an important method of heavy oil processing, and delayed coking unit has developed rapidly. By 2004, the total processing capacity of coking unit reached 32.45 million tons/year, and the processing capacity of delayed coking unit increased by 16 1% during 10 years. The estimated capacity of the delayed coking unit currently under construction is 7 million tons. With the increase of processing sour crude oil,&; Ntilde; The application of circulating fluidized bed (CFB) boiler to treat high sulfur petroleum coke will further develop and popularize delayed coking.
Accelerate the development of residue hydrogenation technology: A 2 million tons/year residue hydrogenation unit independently developed by China was put into operation in Maoming Petrochemical Company. Hydrotreating residual oil as RFCC feedstock can maximize the yield of light oil products and become another heavy oil processing route for processing sour crude oil.
2. Development of clean fuel production technology
The quality of gasoline and diesel is facing the severe challenge of the world clean fuel standard. Strict fuel specifications have been planned. The Euro II standard will be implemented on July 2005 1, the Euro III standard will be implemented in Beijing in 2005, and will be implemented on July 20 10. According to the preliminary assumption, it should be able to meet the EU IV emission requirements before 2008.
3. Hydrogenation is the development direction of technology.
The annual processing capacity of hydrogenation units in China has exceeded 5 1 10,000 tons, accounting for about 20% of the total crude oil distillation capacity, but it is still lower than the world average of 50 1%, which restricts the improvement of product types and product quality in China. Hydrocracking unit is an important method to change product structure and produce middle distillate oil. It can better combine oil refining with petrochemical industry and provide raw materials for aromatic hydrocarbon production and steam cracking. It can directly process sulfur-containing vacuum gas oil (VGO) and upgrade lubricant base oil to API Ⅱ Ⅱ and Ⅲ lubricants. Residue hydrotreating can transform raw materials with high sulfur and metal content, and combined with RFCC, it can produce light products to the maximum extent. Secondary processing oil (such as catalytic light &; Ntilde; Hydroupgrading of diesel oil and LCGO can produce clean fuel. Hydrogenated coking heavy gas oil (HCGO) can be used as FCC feedstock to produce more light distillate oil. The diesel fraction after hydrodesulfurization and hydrodearomatization can meet the quality requirements of world fuel specifications. The FCC gasoline after selective hydrodesulfurization can meet the second and third quality requirements of world fuel regulations. Hydrogenation technology will play an important role in the development of petroleum processing. 1, clean gasoline production technology
China FCC gasoline accounts for more than 80% of the total composition of finished gasoline. The focus of technical development is to reduce the sulfur and olefin content in FCC gasoline.
2, clean diesel production technology
Fushun Petrochemical Research Institute of China Petrochemical Company has successfully developed a new generation of deep hydrodesulfurization catalyst FH-UDS for diesel oil. The catalyst has been used in the diesel hydrogenation unit of Jinling Branch of China Petrochemical Company, and also in Qilu Branch of China Petrochemical Company, Zhenhai Refining and Chemical Company, Maoming Branch and Shanghai Petrochemical Company. When FH-UDS catalyst is used to produce diesel oil with sulfur content meeting Euro III emission standards, its relative volume activity of hydrodesulfurization is 56% higher than that of FH-DS catalyst. The relative volume activity of hydrodesulfurization of FH-UDS is 65438 0.59% higher than that of FH-DS catalyst when producing diesel oil with sulfur content meeting Euro IV emission standard. FH-UDS catalyst takes W-Mo-Ni-Co as the active component, which has the characteristics of large pore volume, high specific surface area, good stability of hydrodesulfurization and hydrodenitrogenation activities, high strength, good stability of refined oil and strong adaptability of raw materials. Clean diesel oil with sulfur content meeting Euro III and Euro IV emission standards can be produced under mild process conditions, and sulfur-free diesel oil can also be produced by properly adjusting operating conditions.

7. Production technology of lube base oil China refining and chemical equipment industry has made good achievements in production scale, industrial structure, product development and domestic production. However, although the overall scale of China's equipment manufacturing industry has been considerable, and many achievements have been made in the research of major projects, only13 of petroleum and petrochemical technology and equipment have reached the international advanced level, and the domestic market satisfaction rate of domestic equipment is less than 60%, accounting for a low proportion in major technical equipment fields. Most of the high-end equipment and manufacturing technology in the industry rely on imports.
From the market point of view, the global petrochemical industry has formed a three-legged pattern of the United States, Asia and Europe, and the refining equipment manufacturing industry in these three regions has also developed rapidly. China's oil refining and chemical equipment market is fiercely competitive, and private enterprises have strong competitive strength and occupy a large market share. With the increasingly heavy and inferior crude oil supply and the increasingly strict requirements of environmental protection laws and regulations on oil quality, the conventional technology of oil refining industry will be continuously improved in the future, and high-end oil refining technology will be more integrated with high-tech and high-tech industries. 20 1 1 year, the sales revenue of private enterprises will account for more than 80% of the industry sales revenue. With the development of China's oil refining and chemical equipment manufacturing industry, many multinational companies have invested and set up factories in China, such as ABB Rhuems, Shore Group, and Japanese steel mills. , which makes the market competition of refining and chemical equipment in China more intense.
