Alkylated oil is the key and ideal component of gasoline above VI in producing countries.
DuPont's sulfuric acid alkylation technology has long been a leader
.

In order to achieve higher gasoline quality upgrades and standards more efficiently, PetroChina needs to increase its production of alkylated oils, and it needs to independently research and develop the technical potential of multiple raw materials to produce higher octane numbers and lower acid consumption

After 7 years of independent research and development, the Petrochemical Institute joined Liaoyang Petrochemical, Lanzhou Huanqiu Engineering Co.
, Ltd.
and Beijing University of Chemical Technology in 2019 to create a complete set of supergravity reaction separation technology
.

This technology has unique advantages in the diversified expansion of raw materials, product quality upgrades, and energy saving and emission reduction capabilities

In the upgrading and upgrading of gasoline quality in China, in addition to the stricter requirements for olefins, aromatics, and oxygen content, the structural contradictions of the blending components that affect the distillation range and octane number of the gasoline pool are gradually emerging, and it is necessary to increase the production of alkylated gasoline.
, Tap the technical potential of multiple raw materials to produce higher octane number and lower acid consumption and energy consumption
.

The strengthening of the supergravity process realizes the instantaneous mixing and mass transfer of the micro-reaction sites, effectively improving the selectivity of the reaction, and increasing the octane number of alkylated products by 1 to 3 units compared with similar foreign technologies

The relevant person in charge of the research team stated that after the demonstration device is successfully started, they will obtain comprehensive and accurate test data in the next two months, summarize engineering design experience, and explore and optimize the operating conditions of the supergravity alkylation process, new packing structure, new sealing and anti-corrosion.
