Document Type and Number:
WIPO Patent Application WO/2024/040803
Kind Code:
A1
Abstract:
Provided are a porous carbon material, and a preparation method therefor and the use thereof. The preparation method comprises the following steps: taking the 250-550ºC fraction of ethylene tar, and hydrotreating the fraction to obtain a hydrofined ethylene tar; pre-carbonizing part of the hydrofined ethylene tar to obtain coke; and mixing the residual hydrofined ethylene tar and the coke to form a mixture, and activating the mixture to obtain a porous carbon material. The preparation of high-purity porous carbon can be achieved, with the preparation process being simple and the cost being low.
