SPECIAL PETROL FOR FIRST CAR REFUELING Russian patent published in 2021 - IPC C10L1/04 C10L1/185 C10L1/16 C10L10/04 

FIELD: oil refining.

SUBSTANCE: invention relates to oil refining, in particular to a composition of car petrol intended for the use as fuel for the first car refueling. Petrol for the first car refueling is proposed that is characterized by compounding of following components: alkylate of plants for petrol production by acid alkylation; isomerizate of an isomerization plant for light petrol fractions with pre-hydrotreating units; butane-butylene fraction from catalytic cracking plants, methyl tert-butyl ether and multifunctional additive HITEC 6437 ECTO with the following ratio, wt.%: alkylate is 51÷75, isomerizate is 15÷35, butane-butylene fraction ≤4, methyl tert-butyl ether ≤15, multifunctional additive HITEC 6437 ECTO ≤0.1.

EFFECT: producing petrol with high octane characteristics both by research and motor methods, low content of harmful emissions released during the combustion process, absence of carbon formation and corrosion properties.
