CATALYST FOR PURIFYING GAS

摘要

PURPOSE:To obtain a catalyst having high oxidation activity and exhibiting characteristic resistance and stability even under the reducing atmosphere by substituting Co at the B site for Fe. CONSTITUTION:The powdered oxides having different compositions are prepared by mixing specified amts. of oxide and carbonate of each component element to obtain the perovskite type compound oxide shown in the formula. The produced material is molded into columnar pellets of about 1g/pellet.
