Abstract
Disclosed is a catalyst for desulfurization, including (a) an oxide selected from among SiO, AlO, FeO, TiO, MgO, MnO, CaO, NaO, KO and PO, (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 (NaBO.10HO), sodium hydroxide (NaOH), sodium silicate (NaSiO) and hydrogen peroxide (HO). 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) can be adsorbed and removed at high efficiency upon combustion of a combustible substance.
