A method for preparing a porous carbon material by using coal tar generated in a coke oven gas (COG) process is provided. The method includes: removing quinoline insoluble (QI) by mixing tetrahydrofuran (THF) with coal tar generated in a COG purification process; distilling coal tar by adding a phenolic resin to the QI-removed coal tar, and heating the same at a temperature of 100&#xb0; C. to 330&#xb0; C.; carbonizing the distilled coal tar by heating the same at 350&#xb0; C. to 600&#xb0; C.; mixing a carbide after the carbonization step and the coal tar, which has been distilled before the carbonization, and grinding/granulating the same; mixing the ground/granulated carbide and the coal tar, which has been distilled before the carbonization, with a pore forming agent, and heat treating the same at 300&#xb0; C. to 500&#xb0; C.; and forming pores by making the heat treated carbon material come into contact with water vapor at 700&#xb0; C. to 1000&#xb0; C.
