Propylene production process
Release time:
2021-11-22
At present, the research on the chemical process of increasing the production of propylene is mainly concentrated in four aspects: one is to improve the FCC and other refining processes, tap the potential of existing equipment, and upgrade the technology of FCC equipment to increase the production of propylene; the second is to make full use of the C4-C8 by-products of oil refining and ethylene cracking And other resources, low-carbon olefin cracking technology and olefin disproportionation technology that are converted into ethylene and propylene; the third is propane dehydrogenation process; the fourth is the methanol-to-olefin process that uses natural gas and coal as raw materials to produce ethylene and propylene.
Increasing production FCC process technology
Compared with traditional FCC, the operating conditions of this kind of process technology are more severe, requiring higher reaction temperature, higher catalyst-to-oil ratio, and shorter catalysis time. Using these technologies, although the gasoline yield will be affected to a certain extent, the olefin content in the gasoline is reduced and the quality is improved. The output of propylene is 2 to 4 times higher than that of the traditional FCC. my country’s oil refining industry has large catalytic cracking processing capacity and high slag mixing ratio, resulting in high olefin content in gasoline. The development and application of the FCC process technology to increase the production of propylene will improve the quality of oil while providing more low-carbon olefins for downstream. Market prospects.

Analysis of Global Lubricant Additives Market Growth in 2025
The global lubricant additives market reached approximately $17 billion in 2024. Entering 2025, the sector continues its robust growth trend, with the market size expected to approach $20 billion and a stable annual growth rate of 6%-8%. This growth pattern is driven by both the sustained support from the traditional fuel vehicle aftermarket and the emerging demand explosions in new energy vehicles and industrial sectors, demonstrating a multi-dimensional industrial transformation.
Growth in China's Lubricant Exports to Africa
In recent years, Chinese lubricants have shone remarkably in the African market, emerging as a dazzling star. Data serves as the most compelling evidence: in 2025, China's lubricant exports to Africa surged by 46% year-on-year, with the export volume doubling in just three years. It is expected to exceed the 300,000-ton threshold within the year, reaching a value of $82.3 million—equivalent to providing full-vehicle maintenance services for 2 million pickup trucks. Behind this growth lies the dual driving force of Chinese lubricant enterprises' precise market strategies and technological innovation.
A brief discussion on the cleaning agent of lubricating oil additive
With the development of industrial technology, modern equipment requirements of high speed, high performance, high automation, high efficiency and long life, in terms of lubrication simply with mineral oil lubrication materials has been difficult to meet. Adding a small amount of other substances to a lubricating material can improve its performance, give it new characteristics, to meet the increasingly harsh use environment, these substances are called lubricating oil additives.
Main function and classification of dispersant lubricant additive （2）
The oil soluble group provided by the dispersant is larger than the purifier, which can effectively prevent the accumulation of carbon and colloidal material together.
Main function and classification of dispersant lubricant additive （1）
In the early stage, the widely used detergent dispersants in internal combustion engine oil are metallic sulfonates, alkyl phenols, phosphonates and alkyl salicylate, which are called metal detergent dispersants. Subsequently developed a metal-free additive, it has excellent dispersion properties, in order to distinguish from the former, people called it ash-free powder.
