ADDITIVE COMPOUND FOR THE CETANE NUMBER BOOST OF THE DIESEL FUEL Russian patent published in 2007 - IPC C10L1/23 

FIELD: oil-processing industry; petrochemical industry; production of the additive compound for the cetane number boost of the diesel fuel.

SUBSTANCE: the present invention is pertaining to the field of oil-processing industry and petrochemical industry, in particular, to the compositions of the additive compounds increasing the cetane number of the diesel fuel. The additive compound for increasing the cetane number of the diesel fuel consists of the preliminary mixed cyclohexanol nitrate and the fraction of the paraffin hydrocarbons of the normal structure from С₉ up to С₂₀ at the mass ratio of the indicated ingredients from 4:1 up to 1:4. The diesel fuel contains this additive compound in the amount of 0.05-0.75 mass %. The additive compound has the synergetic effect. Accretion of the cetane number of the diesel fuel after the additive compound usage exceeds the total effect from usage of its each ingredient. The additive compound due to its higher dissolubility stimulates the process of mixing with the fuel and is cheaper then the rest known additive compounds.

EFFECT: the invention ensures, that the additive compound due to its higher dissolubility stimulates the process of mixing with the fuel and is cheaper then the rest known additive compounds.
