FIELD: chemistry.
SUBSTANCE: invention discloses a fuel composition consisting of residual oil, heavy pyrolysis resin and stabiliser. The stabiliser used is an organic residue obtained from spent sulphuric acid - wastes from sulphuric acid alkylation of isoalkanes with olefins, which is neutralised with ammonium. The neutralisation product is extracted with polar solvents. The organic phase is separated, from which the said organic residue is separated, with the following ratio of components, wt %: heavy pyrolysis resin 25-75, organic residue 0.5-5.0, residual oil - the rest.
EFFECT: invention enables to obtain a stable fuel composition, recycling of the organic residue - by-product of the process.
