Abstract

The invention provides a phenolic resin activated carbon microballon and a rapid preparation method thereof. The rapid preparation method comprises the following steps of: preparing a phenolic resin microballon with a certain size by carrying out spray drying or fluidized bed drying on water-soluble phenolic resin or spirit soluble phenolic resin; thermocuring the microballon; carrying out temperature-rising carbonization on a curing sample in an inert atmosphere; mixing the curing sample (or a carbonized sample) with an active agent; then carrying out temperature-rising carbonized activation in the inert atmosphere; and carrying out cooling, washing, acid washing and washing to obtain a phenolic resin based activated carbon microballon. The invention has the advantages of wide raw material source, low price, simple process, high yield, uniform grain diameter of products, controllable sphere diameter and specific area and convenient industrial implementation.

Description

technical field

[0001] The invention relates to an activated carbon material and a preparation method thereof, in particular to a rapid preparation method of phenolic resin activated carbon microspheres. Background technique

[0002] Porous phenolic resin-based carbon microspheres are widely used in the fields of adsorption and storage, and have great potential application prospects in supercapacitor materials, lithium-ion batteries, and catalysis.

[0003] Since the invention of mesophase carbon microspheres, people have been devoting themselves to the research of preparing carbon microspheres from various raw materials. The preparation of carbon microspheres from pitch must go through a process of oxidation and non-melting of pitch balls, which is time-consuming and energy-consuming, and often has problems such as poor sphericity and difficult control of specific surface area.
