This marks a breakthrough in overcoming the limitations of traditional technologies in the large-scale application of the supergravity reaction and separation system pioneered by Sinopec; it has led to innovations in both process methods and core equipment, thereby establishing an alkylsulfate production technology route that can compete with international advanced levels. Alkylated oils are key ideal components for producing gasoline meeting Tier VI and higher standards, and DuPont’s sulfuric acid alkylation technology in the United States has long held a leading position. To upgrade the quality of gasoline more efficiently, CNPC needs to increase the production of alkylated oil, and it must develop its own technologies to utilize various raw materials in order to produce gasoline with a higher octane rating while reducing energy consumption and acid formation. After 7 years of independent research and development, the Petrochemical Research Institute, in collaboration with Liaoyang Petrochemical, Lanzhou Huanqiu Engineering Co., Ltd., and Beijing University of Chemical Technology, developed a set of ultra-gravity reaction and separation technologies in 2019. This technology offers unique advantages in terms of diversifying raw materials, improving product quality, and enhancing energy conservation and emission reduction capabilities. The enhancement of the hypergravity process enables instantaneous mixing and mass transfer at the micro-scale reaction site, effectively improving the selectivity of the reaction; as a result, the octane number (RON) of the alkylated products increases by 1 to 3 units compared to similar foreign technologies. It has a clear advantage, especially when dealing with C4 containing isobutylene ethers. The new technology also meets the feasibility of independently designing alkylation routes using carbon terpenes and carbon pentene olefins as raw materials; it can optimize the sources of raw materials for alkylation oils in certain refineries, holding great commercial value. Once the demonstration unit is successfully commissioned, the Petrochemical Research Institute will collect experimental data accurately over the next two months, summarize experience in engineering design, and explore technologies such as optimizing the operating conditions of hypergravity alkylation processes, developing new filler structures, new types of seals, and corrosion-resistant materials. It will also study the patterns of long-term stable operation of hypergravity reactors as well as the comprehensive capabilities for developing process packages, in order to accelerate the widespread application of these new technologies.
