Embodiment 1

[0031] After kaolin saturated adsorption weight concentration is 15% ammonium carbonate solution, then mixed with activated carbon, manganese ferromanganese slag A, lanthanum oxide, granulated 2-3mm, dried at 100°C for 8 hours, and then under nitrogen atmosphere, Roasting at a temperature of 1300° C. for 5 hours to obtain catalyst A, the composition of which is as follows: the content of activated carbon is 25%, the content of ferromanganese slag is 25%, the content of lanthanum oxide is 3%, and the balance is kaolin.

Embodiment 2

[0033] Replace manganese ferromanganese slag A in embodiment 1 with ferromanganese slag B, replace lanthanum oxide with cerium oxide, preparation process is the same as embodiment 1, obtains catalyst B, and its composition is as follows: the content of activated carbon is 30%, manganese ferrosite The content of slag is 30%, the content of cerium oxide is 2.5%, and the balance is kaolin.

Embodiment 3

[0035] Kaolin is directly mixed with activated carbon, ferromanganese slag A, and lanthanum oxide without modification, granulated to 2-3mm, dried at 100°C for 8h, and then roasted at 1300°C for 5h under nitrogen atmosphere to obtain Catalyst C, its composition is as follows: the content of activated carbon is 25%, the content of ferromanganese slag is 25%, the content of lanthanum oxide is 3%, and the balance is kaolin.

Abstract

The invention discloses a catalytic oxidation catalyst and a preparation method thereof. The catalytic oxidation catalyst is based on the weight of the catalyst, and its composition includes: the content of clay is 20%-50%, the content of activated carbon is 20%-55%, and the content of ferromanganese slag is 10%-45% , the rare earth content is 0.2%-5%. The preparation method comprises: mixing clay, activated carbon, ferromanganese slag, and rare earth sources, molding, drying, and high-temperature roasting in an oxygen-free atmosphere. The catalytic oxidation catalyst not only turns waste catalysts into valuables, but also has good activity and stability, and is especially suitable for the catalytic oxidation process of wastewater ozone.

Description

technical field [0001] The invention relates to a catalytic material and a preparation method thereof, in particular to a catalytic oxidation catalyst and a preparation method thereof. Background technique [0002] With the progress and development of society, there are more and more types of organic pollutants in industrial wastewater, and the treatment is becoming more and more difficult, but the sewage discharge standards are becoming more and more stringent. At present, effective treatment methods are needed to remove organic pollutants in wastewater. . [0003] Ozone catalytic oxidation technology is an advanced oxidation technology developed in recent years that can degrade organic pollutants that are difficult to be oxidized by ozone alone under normal temperature and pressure. It can continue to oxidize and decompose refractory alcohols, ketones, organic acids and esters. The oxidation of organic pollutants is more thorough and the removal efficiency is high. At pr...
