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 9):
The method of  claim 7 , wherein the metal powder in step (b) includes 0.0035 to 0.009 parts by weight of Li, 0.005 to 0.01 parts by weight of Cr, 0.001 to 0.005 parts by weight of Co, 0.006 to 0.015 parts by weight of Ni, 0.018 to 0.03 parts by weight of Cu, 0.035 to 0.05 parts by weight of Zn, 0.04 to 0.08 parts by weight of Ga, 0.02 to 0.05 parts by weight of Sr, 0.002 to 0.01 parts by weight of Cd and 0.003 to 0.005 parts by weight of Pb.
