Problems solved by technology

There are the following technical problems like this: first, because carbon-rich materials (woody materials, bamboo materials, shell materials and macromolecular materials) generally just can be fully carbonized at 800 ℃ and obtain the carbon material of high porosity, if heat If the decomposition temperature is too high, the carbon material will be excessively pyrolyzed and the carbon yield will be reduced; secondly, due to the high pyrolysis temperature, the porosity (specific surface area) in the carbon particles will also be reduced, and the adsorption of carbon particles will be reduced. Reduced performance; third, higher pyrolysis temperature will also increase energy consumption and increase production costs

Abstract

The invention discloses columnar carbon granules taking illite, a low-temperature flux and walnut shell powder as the main raw materials. The columnar carbon granules consist of basic raw materials and auxiliary raw materials, wherein the basic raw materials comprise 20-60wt% of illite powder, 10-40wt% of low-temperature flux powder and 20-70wt% of walnut shell powder; relative to the basic raw materials, the auxiliary raw materials comprise 0-10wt% of TiO2 powder, 4-6wt% of hydroxypropyl methyl cellulose, 0.5-1.5wt% of oleic acid, 3-6wt% of glycerin and 40-50wt% of water. The melting temperature of the low-temperature flux powder is 600-900DEG C. In addition, the invention further discloses a preparation method of the columnar carbon granules. The walnut shell powder is used as a carbon source, illite is used as a base material, and the low-temperature flux is used as a binding agent to form a formula system, so that the high-strength high-porosity carbon granule material can be prepared at a relatively low temperature, and the preparation method is simple in process flow and easy for industrial production.

Description

technical field [0001] The invention relates to the technical field of carbon materials, in particular to columnar carbon particles with illite, low-temperature flux and walnut shell powder as main raw materials and a preparation method thereof. Background technique [0002] Activated carbon (AC) is a kind of porous material with excellent performance. It usually uses carbon-rich materials (wooden materials, bamboo materials, fruit shell materials and polymer materials, etc.) Styling substances. Due to its highly developed porosity, high specific surface area and catalytic performance, it is widely used in environmental protection industry, medical treatment, chemical industry, food and other related fields. [0003] However, the activated carbon obtained by pyrolysis of carbon-rich materials cannot meet the requirements of use due to its low particle strength, or the obtained activated carbon is in powder form, which will cause dust during use and is not easy to recycle, r...
