Embodiment 1

[0057] Municipal solid waste from Wuluju garbage compression and transfer station in Haidian District, Beijing was selected, and the composition of the garbage was tested as shown in Table 1 below:

[0058] Table 1: Composition of MSW

[0059]

[0060] Carry out high-temperature distillation and carbonization of the above-mentioned garbage through the following steps: After removing the dregs, glass, stones, ceramics and metals in the garbage through a garbage sorting machine such as a specific gravity sorting machine, put the garbage into the garbage transport device, and then put the garbage Pulverize; pass the garbage transport device through the high-temperature distillation carbonization device; take out the gas stream from the upper part of the high-temperature distillation carbonization device; pass the gas stream through the catalyst bed in gaseous form; condense and separate the effluent from the catalyst bed to obtain a liquid combustible material and water; carbo...

Abstract

The invention provides a method for producing a carbon material. The carbon material is prepared from living garbage through pyrolysis carbonization and further modification. The carbon material can be used as an absorbent. The carbon material prepared by using the method is low in cost and good in adsorption effect.

Description

technical field [0001] The invention belongs to the technical field of carbon material production, and in particular relates to a method for preparing carbon material, especially activated carbon, by pyrolysis and carbonization of household garbage. Background technique [0002] Activated carbon is a porous carbon-containing substance with a highly developed pore structure and a high specific surface area. It is an excellent adsorbent and catalyst carrier. The adsorption is achieved through physical adsorption and chemical adsorption. In addition to carbon elements, its constituent materials still contain a small amount of hydrogen, nitrogen, oxygen and other elements, and its structure is formed by the accumulation of hexacyclic compounds formed by carbon. Due to the irregular arrangement of six-ring carbon, activated carbon has the characteristics of multi-microporous volume and high surface area. [0003] Municipal solid waste usually refers to urban solid waste, which ...
