Embodiment Construction

[0021] A production method of industrialized supercapacitor activated carbon,

[0022] 1. Selection of raw materials

[0023] Use high-quality petroleum coke, crush it to 180 mesh, and the sieving rate is ≥90%; use high-quality gelatin carbonized material and / or high-quality biomass carbonized material as the modified material, and crush it to 180 mesh, and the sieving rate is ≥90%; Pure potassium hydroxide powder, mass percentage content ≥ 90%;

[0024] The mass ratio between the three raw materials is high-quality petroleum coke:modified material:activator=1:0.05~1.6:0.8~3.9,

[0025] High-quality gelatin carbonized material is obtained after carbonization pretreatment of gelatin; high-quality biomass carbonized material is obtained after carbonization pretreatment of raw materials such as plant husks.

[0026] When the modified material is a mixture of high-quality gelatin carbonized material and high-quality biomass carbonized material, it can be mixed in any proportion....

Abstract

A production method of industrial super capacitor active carbon adopts high-quality petroleum coke; a modified material is selected from a high-quality gelatin carbonized material and / or a high-quality biomass carbonized material; an activator is selected from high-purity potassium hydroxide powder; the mixture is stirred and pretreated by carbonization; an activation reaction is completed in an activation furnace; an activation reactor has filler-type labyrinth seal design; little air passing through the labyrinth is controlled and consumed by the spontaneous combustion of the sealed fillers; oxygen is effectively isolated, and the reaction is protected. discharging is performed after activator recovery, boiling with acids, and repeatedly washing; then drying, grinding, and vacuum packaging and warehousing are performed. The production process is short and practical; the quality control is stable and reliable; the production is low in cost and free of pollution; directional modification and continuous mechanized large-scale production of the product are realized.

Description

technical field [0001] The invention relates to a production and processing technology of new energy materials, in particular to a production method of industrial supercapacitor activated carbon. Background technique [0002] With the rapid development of new energy, new materials, and new processes, the generation and application of supercapacitors are driving the development of a new industrial chain. Supercapacitors are between batteries and ordinary capacitors. They have the characteristics of large current and fast charge and discharge of capacitors, and also have the characteristics of energy storage of batteries, and have a long repeated service life. When discharging, they use electrons between moving conductors (instead of relying on chemical reactions) Discharges the current, thereby providing power to the device. [0003] Activated carbon for supercapacitor has high specific surface area and well-developed mesopores, reasonable pore structure distribution, and ...
