Blast furnace gas infrared radiation combustion and CO oxidation catalysis checker brick and preparation method thereof
The invention relates to a blast furnace gas infrared radiation combustion and CO oxidation catalysis checker brick and a preparation method thereof.The checker brick comprises a checker brick base body and active components, the checker brick base body is made of mullite corundum refractory materials, and the active components comprise, by weight, 10-12 parts of CuOx, 8-10 parts of CrOx, 5-7 parts of MnOx, 6-8 parts of FeOx, 1-3 parts of NiOx, 1-3 parts of Pt, 1-3 parts of ZrOx, 1-3 parts of Pd, 1-3 parts of Fe12O19Sr and 1-3 parts of CoFe2O4. The active component comprises the following components in parts by weight: 4-6 parts of NiOx, 1-2 parts of Pt, 2-4 parts of ZrOx, 5-7 parts of Pd, 3-5 parts of Fe12O19Sr and 2-4 parts of CoFe2O4, and the active component is loaded on the checker brick matrix through a dipping or precipitation method. According to the present invention, the original blast furnace gas infrared radiation combustion of the checker brick is maintained, the CO oxidation catalysis function is provided, and the CO in the flue gas can be subjected to oxidation catalysis removal and emission reduction at the sintering flue gas temperature (180-300 DEG C).
本发明涉及一种高炉煤气红外辐射燃烧兼CO氧化催化格子砖及其制备方法，包括格子砖基体及活性组分，所述格子砖基体由莫来石刚玉耐火材料制成，所述活性组分包括CuOx、CrOx、MnOx、FeOx、NiOx、Pt、ZrOx、Pd、Fe12O19Sr和CoFe2O4，其中，按照重量份计，包括以下组分：CuOx为10‑12份，CrOx为8‑10份，MnOx为5‑7份，FeOx为6‑8份，NiOx为4‑6份，Pt为1‑2份，ZrOx为2‑4份，Pd为5‑7份，Fe12O19Sr为3‑5份，CoFe2O4为2‑4份，所述活性组分通过浸渍或沉淀方法负载在所述格子砖基体上。本发明不仅在保持格子砖原有的高炉煤气红外辐射燃烧的同时，还具有具备CO氧化催化功能，而且可以在烧结烟气温度下（180‑300℃)将烟气中的CO氧化催化脱除和减排。
