Industry, agriculture and many other fields. In recent years, one of the research hotspots of activated carbon is to use cheap agricultural and forestry wastes as raw materials and simple and clean process to prepare biomass activated carbon with high economic benefit and good adsorption performance. If the agricultural and forestry wastes are effectively utilized and turned into treasures, it can not only create certain economic benefits, but also reduce its pollution to the environment, and achieve the purpose of treating waste with waste. In this paper, using biomass (corn cob, rice husk and peanut shell) as raw material, the experimental research on the preparation of activated carbon from biomass was carried out on the self-built experimental platform, and the activation temperature, activation time, impregnation ratio and impregnation time and other activation and physicochemical characteristics were systematically studied.The granular activated carbon with high strength was prepared by heating wood phosphate mixture at low temperature and using tar generated during its pyrolysis as binder. In this paper, the process conditions and plasticizing mechanism of granular activated carbon prepared by phosphoric acid were studied, which provided scientific data and theoretical basis for the preparation of high strength granular activated carbon. Fir chip as the raw materials, H - POs as activator, using single factor analysis and orthogonal experimental design method, this paper discusses the influence granular activated carbon pore structure and the iodine adsorption value, methylene blue and strength of various preparation factors, determine the optimum process conditions of preparation of granular activated carbon phosphoric acid, phosphoric acid concentration is 70%, dipping 180%, kneading temperature is 170 ℃, for 60 min kneading time, activation temperature is 350 ℃, the activation time of 210 min. The iodine adsorption value, methylene blue adsorption value, strength and BET specific surface area of GAC were 1020.04mGG, 225mg/g, 88.73% and 1486.48m2/g respectively. The experimental results show that the impregnation ratio and carbon activation temperature have great effects on the adsorption performance of GAC, while the kneading temperature and impregnation ratio have great effects on the strength of GAC.Because the strength of GAC decreases with the increase of impregnation ratio, and the decrease range is large, so the preparation of GAC with compound activator is proposed.
