Abstract—

The current level of technological development of the automotive industry imposes demands on the quality of commercial gasoline. The degree of engine boost and the improvement of its design significantly affect the requirements for the detonation resistance of gasoline, which is determined by the octane rating. However, the race for high octane values sometimes contradicts the solution of environmental problems. Thus, along with ensuring that the engine operates at the declared power and efficiency, the fuel must comply with the EURO environmental standards for emissions of harmful substances into the atmosphere. It is this quality system that limits the content of aromatic hydrocarbons in gasoline (the transition from 50 to 25%), which for many years have been solving the issue of increasing the octane number. Currently, isomerization and sulfuric acid alkylation processes are used to produce high-octane gasoline. To increase the efficiency of a sulfuric acid alkylation reactor, the authors of the article conduct numerical modeling of a new design of a feed collector with V-shaped nozzles.
