Title:
METHOD AND SYSTEM FOR PRODUCING DIESEL FUEL HAVING IMPROVED PROPERTY
Document Type and Number:
WIPO Patent Application WO/2022/075348
Kind Code:
A1
Abstract:
The present invention is for producing a diesel fuel having, as compared to a source oil in a starting material, at least one improved property selected from the group consisting of the cetane rating, cetane index, polycyclic aromatic mass, flash point, sulfur content mass, residual carbon content mass of a 10%-residual oil, pour point, ash content mass, and viscosity. In order to do so, the present invention involves: preparing an aqueous phase by mixing a water soluble alcohol with respect to an enzyme aqueous solution containing 0.01-0.10 mass% of lipase as a first enzyme, so as to obtain an alcohol aqueous solution having a concentration of 20-35%; preparing an oil phase by adding, to the source oil, a second enzyme diesel oil solution obtained by dissolving 0.0001-0.01 mass% of a pineapple-derived enzymes including bromelain in a diesel oil; adding, to the oil phase, the aqueous phase such that the volume ratio of aqueous phase : oil phase becomes 2 to 4 : 8 to 6 while maintaining a temperature lower than 60°C; and mixing the oil phase and the aqueous phase and bringing same into contact with each other through shaking or stirring at normal temperature to cause a reaction between the aqueous phase and the oil phase to improve the property of the oil phase and to produce said diesel fuel.
