(A) at least one oxide selected from the group consisting of SiO 2 , Al 2 O 3 , Fe 2 O 3 , TiO 2 , MgO, MnO, CaO, Na 2 O, K 2 O and P 2 O 3 ; (b) at least one metal selected from the group consisting of Li, Cr, Co, Ni, Cu, Zn, Ga, Sr, Cd and Pb; And (c) four sodium borate (Na 2 B 4 O 7 ยท 10H 2 O), sodium hydroxide (NaOH), sodium silicate (Na 2 SiO 3) and hydrogen peroxide, at least one selected from the group consisting of (H 2 O 2) And a liquid composition. The catalyst for desulfurization according to the present invention forms a 2: 1 layered structure in which one octahedron layer is inserted between two tetrahedron layers, and only two out of three positive holes in the octahedral layer are filled, And is chelated together with metal ions to form a metal chelate compound, thereby adsorbing and removing sulfur oxides (SO x ) with high efficiency when the combustible is burned. |
