Columnar activated carbon and preparation method thereof

Abstract

The intention relates to columnar activated carbon and a preparation method thereof. The columnar activated carbon comprises the following components: 15-30 parts of pulverized coal, 20-50 parts of bentonite, 30-50 parts of wood powder carbon, 5-15 parts of medical stone powder, 2-5 parts of an adhesive, 1-3 parts of an activating agent and 2-5 parts of an acidifying agent, wherein the columnar activated carbon comprises the following components: 20 parts of pulverized coal, 30 parts of bentonite, 40 parts of wood powder carbon, 10 parts of medical stone powder, 3 parts of an adhesive, 2 partsof an activating agent and 4 parts of an acidifying agent; the manufacturing process comprises the steps of selecting, mixing, powdering, bonding, forming, drying and activating, specifically, coal slime is subjected to flotation treatment till the ash content is not larger than 25%, and then dried, crushed and sieved through a 200-mesh sieve, coal slime powder is obtained for standby application, and mixing is conducted by mixing the components according to the proportion for standby application, wherein the powdering in the manufacturing process is to grind the mixed raw materials into finepowder, and the bonding in the manufacturing process is to blend the raw materials into mud by adding water and the adhesive, and the materials are mixed into a paste; the columnar activated carbon has the advantages of convenience in use, simple manufacturing process and energy conservation.

Description

technical field [0001] The invention belongs to the technical field of preparing activated carbon, and in particular relates to a columnar activated carbon and a preparation method thereof. Background technique [0002] As an important porous functional material, activated carbon has been widely used in environmental protection, air purification, decolorization and deodorization, solvent recovery, catalyst carrier and other fields. For activated carbon, the pore size and quantity of the pore structure directly affect its use and adsorption effect. Therefore, it is very important to control the pore structure reasonably. At present, the common pore structure control technologies can be divided into: activation process control method, heat treatment method, template method, chemical vapor deposition method and additive method. In terms of application, the activation process control method and the additive method have more advantages. However, regardless of the physical activ...

AI Technical Summary

Problems solved by technology

However, regardless of the physical activation method or chemical activation method, the pore size distribution of the prepared activated carbon is relatively dispersed, and the microporosity is generally high, which limits its practicability; the application of activated carbon is very wide, and the main function of activated carbon is Its adsorption, adsorption can be used in many places, such as absorbing impurities, purifying air, etc. Activated carbon has many benefits, but in the production process, it will also encounter some problems, such as the shape of activated carbon, environmental pollution etc. The shape of activated carbon is different, so that its application is also different. The present invention researches and develops columnar activated carbon, and develops a columnar activated carbon that is easy to use, simple in production process, and energy-saving and its preparation method.
