摘要
The present invention comprises the steps of preparing a lignocellulosic biomass, immersing the lignocellulosic biomass in an alkaline solution to perform alkaline pulping to obtain black liquor, and the alkaline pulping ( oxidizing the black liquor obtained by pulping) to obtain a black liquor oxidized solution, performing a sulfomethylation reaction on the black liquor oxidized solution, and the sulfomethylation reaction product A method for producing porous activated carbon comprising the steps of obtaining lignosulfonate by drying and heat-treating the lignosulfonate to obtain porous activated carbon, a method for producing a supercapacitor electrode using the porous activated carbon, and the method It relates to a supercapacitor using a supercapacitor electrode. According to the present invention, it is possible to prepare lignosulfonate from lignocellulosic biomass, and use the lignosulfonate to prepare porous activated carbon having an excellent specific surface area.
