▎ 摘  要

NOVELTY - Preparation of high-performance activated coke comprises mixing raw coal, activated blue carbon and rare earth elements at mass ratio of 20-80:5-40:0.02-0.1, grinding to 200 mesh to obtain raw material powder, adding raw material powder, nano corn starch and water to kneader, kneading to obtain kneading material, sending kneaded material to granulator for granulation, drying until the moisture is 5-10%, sending to carbonization activation device for carbonization activation, cooling to obtain primary activated coke, mixing primary activated coke and graphene oxide solution, polyacrylonitrile carbon fiber and solid hydrogel particles, molding, pressing and drying. USE - The preparation of high-performance activated coke is used for flue gas purification. ADVANTAGE - The coke has strong adsorption capacity, excellent wear resistance, pressure resistance and desulfurization and denitration performance.
