Document Type and Number:
WIPO Patent Application WO/2023/282363
Kind Code:
A1
Abstract:
A method for pretreatment desulfurization of ship fuel oil by using a pretreatment desulfurization agent of the present invention is characterized in that a catalyst for pretreatment desulfurization is produced comprising: (a) at least one oxide selected from the group consisting of SiO2, Al2O3, Fe2O3, TiO2, MgO, MnO, CaO, Na2O, K2O, and P2O3; (b) at least one metal selected from the group consisting of Li, Cr, Co, Ni, Cu, Zn, Ga, Sr, Cd and Pb; and (c) at least one liquid composition selected from the group consisting of sodium tetraborate (Na2B4O7·10H2O), sodium hydroxide (NaOH), sodium silicate (Na2SiO3), and hydrogen peroxide (H2O2), and the pretreatment desulfurization agent is fed at a predetermined proportion into a fuel supply line for a ship engine, through which ship fuel oil is supplied, so that the ship fuel oil and the pretreatment desulfurization agent are supplied in a mixed state to a ship engine, and thus sulfur oxides are adsorbed and removed during the combustion of the mixed fluid.
