Abstract:
Disclosed is a catalyst for desulfurization, including (a) an oxide selected from among 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) a metal selected from among Li, Cr, Co, Ni, Cu, Zn, Ga, Sr, Cd and Pb, and (c) a liquid compound selected from among sodium tetraborate (Na 2 B 4 O 7 .10H 2 O), sodium hydroxide (NaOH), sodium silicate (Na 2 SiO 3 ) and hydrogen peroxide (H 2 O 2 ). The catalyst of the invention has a 2:1 type layered structure in which one octahedral layer is interposed between two tetrahedral layers and which has a net negative charge due to occupation of only two of three positively charged sites in the octahedral layer, and the catalyst for desulfurization is provided in the form of a metal chelate compound through chelation with a metal ion, whereby sulfur oxide (SO x ) can be adsorbed and removed at high efficiency upon combustion of a combustible substance.

Claim (Index 13):
The method of  claim 7 , wherein the catalyst for desulfurization formed in step (c) is used in a form of a powder catalyst for desulfurization obtained by subjecting the catalyst for desulfurization to precipitation, separation and drying; and a liquid catalyst for desulfurization, which remains after separation of the precipitated catalyst for desulfurization.
