摘要： An ozonation-based method for producing a cementitious material comprises the steps of: (1) mixing a flue gas with an ozone-containing gas to form a mixed flue gas; and introducing the mixed flue gas into an absorption tower, where the mixed flue gas undergoes dry desulfurization and denitrification by reacting with a powdered desulfurizing and denitrificating agent and becomes a treated flue gas; (2) subjecting the treated flue gas to dust removal to generate by-products; and (3) uniformly mixing raw materials that comprise the first by-product, magnesium oxide, fly ash and an additive to give a cementitious material, wherein on the basis of 100 parts by weight of the cementitious material, the first by-product is 20-60 parts by weight, magnesium oxide is 16-33 parts by weight, the fly ash is 15-35 parts by weight, and the additive is 1-15 parts by weight.

摘要： The present disclosure provides a cementitious material and production method thereof. The method comprises steps of: (1) dry desulfurization and denitrification of a flue gas with a flue gas absorbent to give a by-product, wherein the flue gas absorbent comprises 10-23 parts by weight of a nano-sized metal oxide, 10-23 parts by weight of a micro-sized metal oxide, and 40-60 parts by weight of magnesium oxide, the nano-sized metal oxide being selected from one or more of the group consisting of SiO2, CaO, Fe2O3, Al2O3, CuO, V2O5 and MnO2, and the micro-sized metal oxide being selected from one or more of the group consisting of SiO2, CaO, Fe2O3, Al2O3, CuO, V2O5 and MnO2; and (2) uniformly mixing the by-product with magnesium oxide, an industrial solid waste and an additive to give the cementitious material.

摘要： The present disclosure discloses a dry desulfurizing and denitrificating agent and its preparation method and applications. The desulfurizing and denitrificating agent is made of raw materials comprising the following components based on 100 parts by weight of the desulfurizing and denitrificating agent: 30-60 parts by weight of TiO2, 10-30 parts by weight of ZrO2, 2-10 parts by weight of V2O5, 2-10 parts by weight of CoO, 1-8 parts by weight of Co2O3, 2-10 parts by weight of Fe2O3, 5-15 parts by weight of MnO2, and 2-10 parts by weight of KMnO4. The desulfurizing and denitrificating agent of the present disclosure has a good catalytic oxidation performance on sulfur dioxide and nitrogen oxides of flue gas, and a high rate of desulfurization and denitrification.
