| description | This invention relates to the petrochemical industry, in particular, to a method for improving the storage stability ofbiodiesel fuel via using an antioxidant additive. A method for improving the storage stability of biodiesel fuel, comprising addition of an alkylphenol-based antioxidant additive via providing an initial solution that contains 6 to 48 mass % of the alkylphenol-based composition comprised of, mass %:
2,6-di- tert -butyl-4-methylcyclohexanone - 0.2 - 0.3;
2,6-di- tert -butylphenol - 0,7 - 6.0;
2- sec -butyl-6- tert -butyl- p -cresol- 1.5 - 5.0;
4,6-di- tert -butyl- o -cresol - 3.0 - 8.0;
2,4-di- tert -butylphenol - 0.3 - 0.5;
2,4-di- tert -butyl-6-dimefhylaminomethylphenol-2.0 - 5.0;
4,4-methylene-bis(2,6-di- tert -butylphenol) - 0.1 - 0.3; and
2,6-di- tert -butyl-4-methylphenol - to the balance,
dissolved in biodiesel fuel; and adding the solution of the composition to the biodiesel fuel to reach a concentration of the composition of from 0.002 to 1.6 mass % based on the entire biodiesel fuel solution. The technical result consists of a considerable improvement of the storage stability of biodiesel fuel with a reduced amount of the antioxidant additive. The antioxidant additive used inhibits precipitation during the shelf life of biodiesel fuel for a longer period of time. |
