The article provides the results of applied mathematical model of sulfuric acid catalyzed alkylation of isobutane with olefins. It was shown that increasing the content of propylene in the feedstock to 2% leads to decrease in octane number of alkylate to 0.5-1.0 points. Alkylates produced from feedstock with less isobutane mass fraction have a smaller value of octane number. Using mathematic model it was determined that the main parameter influencing the acid activity in the alkylation process is the fresh acid concentration.
