Problems solved by technology

In the thermal regeneration process, the activated carbon after adsorption saturation has to be treated at a high temperature of 800-850°C, which consumes a lot of energy; at the same time, the high-temperature operation makes the adsorption capacity loss rate of activated carbon large, and the adsorption capacity loss of activated carbon is 5-15% every time regeneration

Abstract

An adsorptive catalyst for treating the benzene contained sewage contains Cu (1-5 Wt%), auxiliary component (1-5) chosen from K, Zn and Ce, and activated carbon (85-98 Wt%) as carrier. Its application includes such steps as passing said sewage through said catalyst while adsorbing, drying, filling oxidizing gas and reaction.

Description

technical field [0001] The invention belongs to an adsorption-catalyst and its application method, in particular to a preparation and application method of a multi-component adsorption-catalyst with transition metal as the main active component. Background technique [0002] Phenol-containing wastewater comes from a wide variety of sources. Coking plants, oil refineries, petrochemical plants, gas generating stations, plastic plants, resin plants, insulating material plants, wood preservative plants, pharmaceutical plants, and synthetic fiber plants all produce wastewater containing phenol. The importance of phenols in water pollution is attributed to their extremely high toxicity to aquatic life and difficulty in biodegradation. All countries in the world strictly limit the content of phenol in the environment. my country stipulates that the maximum allowable concentration distribution of volatile phenols in water bodies is: 0.002mg / l for drinking water, 1.0mg / l for agricu...
