<p>The invention relates to the enrichment of petrol and petroleum products with isoparaffin and aromatic hydrocarbons accompanied by a simultaneous removal of injurious additives, mainly sulphur, nitrogen and oxygen treating a feed stock by microbiological means for isomerisation and aromatising hydrocarbons which have a boiling temperature equal to or less than 200 °C. In order to break up high-boiling policyclic, polyaromatic, methane and hybrid petroleum hydrocarbons in such a way that lighter low-boiling cyclic, aromatic, isoparaffin and light methane hydrocarbons are produced, injurious additives are removed, said microbiological means contains micro-organisms of the Thiobacillus aquesullis species in a biologically acceptable medium. The inventive microbiological means can also contain microorganisms of Thiobacillus thioparus and/or Thiobacillus denitrificans in any qualitative combination thereof. The enrichment process is carried out in a reactive medium at a temperature ranging approximately from 4 °C to 60 °C and a pH ranging approximately from 6.0 to 9.0 when said solution is agitated.</p> |
