Embodiment Construction

[0015] A preparation method based on the activated carbon material of Tongcao / Rush grass interconnected porous structure, comprising the following steps:

[0016] (1) Now pre-treat the grass or rushes by cleaning, segmenting, drying, etc., then put the grasses or rushes in a high-temperature furnace, pass inert gas, and heat them at 300-900°C (for example, 300°C, 600°C, 900°C, etc.) ℃) under carbonization for 0.5-8h (for example, 0.5h, 4h, 8h), to obtain the grass- or rush-based carbon materials;

[0017] (2) Proportion of the grass or rush grass-based carbon material and the activator: the mass of the grass or rush grass-based carbon material: activator = 1:0.5-8 (example 1:0.5, 1:4, 1:8) Mix and impregnate for 1-12h (example 1h, 6h, 12h), dry and grind at 50-120°C (example 50°C, 90°C, 120°C) to obtain the mixture;

[0018] (3) Treat the mixture at 300-900°C (example 300°C, 600°C, 900°C) for 0.5-8h (example 0.5h, 4h, 8h) under the protection of an inert gas, cool to room tem...

Abstract

The invention discloses a preparation method of an activated carbon material based on a tetrapanax papyriferus / juncus roemerianus interconnected porous structure. The preparation method comprises thefollowing steps: putting tetrapanax papyriferus or juncus roemerianus into a high-temperature furnace and introducing inert gas to carbonize the tetrapanax papyriferus or juncus roemerianus to obtaina tetrapanax papyriferus or juncus roemerianus-based carbon material; mixing, impregnating, drying and grinding the tetrapanax papyriferus or juncus roemerianus-based carbon material with an activatorto obtain a mixture; and treating the mixture for 0.5-8 hours at 300-900 DEG C under protection of inert gas, naturally cooling the mixture to room temperature, washing the mixture with HCl and deionized water repeatedly till the pH is 7 and finally, drying the mixture to obtain the multilayered porous activated carbon based on the tetrapanax papyriferus and juncus roemerianus. By taking green biomass as a carbon source, the material is wide in source, low in price, simple in process, easy to control, environment-friendly and suitable for scaled production.

Description

technical field [0001] The invention relates to a preparation method of an activated carbon material based on the interconnected porous structure of sage grass / rush grass. Background technique [0002] The preparation of existing activated carbon materials has limited carbon source, high price and complex process, which needs to be further improved. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing an activated carbon material based on the interconnected porous structure of sage grass / rush grass, which uses green biomass as the carbon source, has wide sources, low price, simple and easy-to-control process, and is environment-friendly. [0004] Technical solution of the present invention is: [0005] A kind of preparation method based on the activated carbon material of sage grass / rush grass interlinked porous structure, it is characterized in that: comprise the following steps: [0006] (1) Put the grass or rush ...
