Solid desulfurization and denitrification agent

Abstract

The invention discloses a solid desulfurization and denitrification agent, and belongs to the technical field of catalyst preparation. The catalyst comprises the following raw materials: iron oxide, manganese dioxide, urea, calcium magnesium acetate, titanium oxide, kaolin and calcium carbonate. By further optimizing formula components of the solid denitrification agent, the technical effect of denitrification while desulfurization is achieved, specifically, the adsorption and removal capacity of calcium carbonate is enhanced through modification, the desulfurization and denitrification effects are good, the denitrification rate reaches 80% or above, and the desulfurization effect reaches 97% or above.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to a solid desulfurization and denitrification agent. Background technique [0002] NO X and acidic SO 2 However, due to coal combustion, garbage incineration and economic development, the pollutants discharged from the production process of enterprises under working conditions cannot be significantly reduced in a short period of time, and environmental pollution problems cannot be avoided. Among them, nitric oxide and di Nitrogen oxides are an important cause of photochemical smog and acid rain. Nitrogen oxides are harmful to the human respiratory system. Long-term inhalation of nitrogen oxides may cause changes in lung structure, while acidic SO 2 Mainly cause different degrees of irritation of the respiratory tract and eye mucous membranes. [0003] In order to reduce pollution, there is a dry desulfurization absorption technology in the prior art, which has the a...
