The low temperature of sintering flue gas limits the application of common vanadium- and titanium-based catalysts if flue gas is not reheated. In this study, cylindrically molded activated coke was prepared from steel slag and coke powder of an iron and steel plant for low-temperature denitration. The fraction of activated coke precursor and activation conditions were optimized by orthogonal experiments and the response surface method, respectively. Denitration tests on low-temperature simulated sintering flue gas and characterization of the physical and chemical properties of the activated coke were carried out. Fe₂O₃ of steel slag showed catalytic reductive activity.

活性焦与钢渣、焦粉混合后的NO去除

如果烟气不重新加热，烧结烟气的低温限制了普通钒基和钛基催化剂的应用。本研究以某钢铁厂的钢渣和焦粉为原料，制备圆柱状成型活性炭用于低温脱硝。分别通过正交实验和响应面法优化了活性焦前驱体的比例和活化条件。对低温模拟烧结烟气进行了脱硝试验，并对活性焦的理化性质进行了表征。钢渣的Fe ₂ O ₃表现出催化还原活性。
