<h1 class="pgc-h-arrow-right" data-track="1" > ash-free dispersant plays an important role in oil production The future market prospect is broad</h1>
Dispersant is a surfactant that uniformly disperses insoluble particles, prevents particles from settling and condensing, and forms a stable suspension, with two characteristics: lipophilic and hydrophilic. Ashless dispersant is a kind of dispersant, mainly used as an additive in the production of lubricating oil and fuel oil, which can effectively control the formation of sediments in the engine, combustion chamber, intake air and other systems to achieve the purpose of cleaning.
There are many types of ashless dispersants, which are divided according to raw materials, mainly including polyisobutylene succinimide, polyisobutylene succinate, benzylamine, ash-free phosphate, high molecular weight ash-free dispersant, boron-modified ash-free dispersant, etc. Since the 1960s, the ash-free dispersant market has developed rapidly and is widely used in gasoline, diesel, lubricating oil and explosive emulsifiers, of which gasoline, diesel and lubricating oil are its important application markets.
Ashless dispersant is used in fuel oil and lubricating oil, when the engine operating temperature is low, it can inhibit the generation of sludge, avoid oil circuit blockage, parts corrosion or wear, but also at high working temperatures, inhibit the formation of sediment in the engine parts, thereby improving the engine running stability and service life. With the improvement of oil grade, the use of ashless dispersants has gradually increased, especially in high-end lubricating oils, which have a wide range of applications and a high proportion of additions.
According to the "2021-2025 Ashless Dispersant Industry In-Depth Market Research and Investment Strategy Recommendation Report" released by the New Thinking Industry Research Center, the global ashless dispersant market size is about 3.42 billion US dollars in 2020. With the trend of high-end automobile consumption in China becoming more and more obvious, and the requirements of car owners for automobile maintenance continue to increase, the quality and environmental protection of oil products such as lubricating oil in the Chinese market continue to increase, and the ash-free dispersant has good dispersion in addition to good dispersion, but also has good antioxidant, anti-wear and other characteristics, so it is widely used in lubricating oil, especially high-end lubricating oil, and the future market prospect is broad.
In China's market, the ashless dispersant production enterprises mainly include Sinopec Yangzi Petrochemical Co., Ltd., China National Petroleum Corporation Jinzhou Petrochemical Branch, Jinzhou Kangtai Lubricating Oil Additive Co., Ltd., Jinzhou Huifa Trina Chemical Co., Ltd., Xinxiang Ruifeng New Material Co., Ltd., Wuxi Southern Petroleum Additives Co., Ltd. and so on. Among them, the Great Wall brand lubricants produced by Sinopec account for a relatively high share of China's lubricant market, and the development of ash-free dispersants is conducive to the further improvement of its petrochemical industry chain layout.
New Thinking industry analysts said that ashless dispersion is a functional additive, in the lubricating oil, fuel oil production of important position, especially with the market for lubricating oil quality requirements continue to improve, ash-free dispersant demand continues to increase. China has the ability to produce ash-free dispersible doses, in the production enterprises, some enterprises petrochemical industry chain layout is relatively perfect, ash-free dispersants are mainly self-use, compared with the industrial chain layout of a single ash-free dispersant enterprises, with higher anti-risk ability.
