COPPER-IRON OXIDE CATALYST AND DECOMPOSITION OF SULFURIC ACID USING SAME

摘要

An economical sulfuric acid decomposition catalyst capable of maintaining excellent reaction activity and stability at high temperatures and high pressures is provided, and a method for decomposing sulfuric acid using the catalyst is provided. A copper-iron binary oxide catalyst comprises a copper oxide and an iron oxide at a copper to iron molar ratio of 1:0.5 to 2.0. The copper oxide and the iron oxide are supported on a support. The copper-iron binary oxide catalyst comprises the support and the copper and iron oxides at a molar ratio of 1:0.1 to 1.0. The support is selected from the group consisting of silica, alumina, zirconia, titania, and mixtures thereof. A method for decomposing sulfuric acid comprises decomposing sulfuric acid in the presence of a copper-iron binary oxide catalyst comprising a copper oxide and an iron oxide at a copper to iron molar ratio of 1:0.5 to 2.0. The decomposition process is conducted at a temperature of 500 to 1200 deg.C and a pressure of 0.1 to 40 atmospheric pressures.
