Activation regeneration treatment process for semi-coke used for industrial flue gas dry desulfurization

Abstract

The invention provides an activation regeneration treatment process for semi-coke used for industrial flue gas dry desulfurization. The activation regeneration treatment process comprises the semi-coke. The semi-coke is successively subjected to water vapor activation, nitric acid activation and potassium hydroxide activation, so a semi-coke activation product with good sulfur dioxide adsorption performance is obtained; and the semi-coke activation product reaches the standards of flue gas adsorption, has low price, is applicable to large-range flue gas treatment, and has high environmental friendliness and economic benefits.

Description

technical field

[0001] The invention relates to the field of environmental protection, in particular to an activation regeneration treatment process for semi-coke used in industrial flue gas dry desulfurization. Background technique

[0002] Sulfur dioxide and nitrogen monoxide in coal-burning flue gas are the main air pollutants and the main cause of acid rain. Therefore, the control of their emissions has become the focus of my country's environmental protection work. Among many flue gas desulfurization and denitrification technologies, wet desulfurization and denitrification technology has the problem of secondary pollution due to its low desulfurization and denitrification efficiency; dry desulfurization and denitrification technology has no secondary pollution, resources can be recycled, catalysts can be recycled, etc. Advantages, gradually become the trend of flue gas purification technology development. The electron beam method and pulse spot halo method in dry desul...
