Abstract


In detail in this paper preparation, high specific surface area activated carbon molding and application at home and abroad on the basis of research progress, mainly introduced the application of oil and gas adsorption and the electric double layer capacitor. With petroleum coke and paper-making black liquor mixed some coconut shell as raw material, KOH as activator, the preparation of petroleum coke under the condition of nitrogen protection activated carbon and activated carbon black liquor, the surface area of 2775 m2 / g respectively and 2113 m2 / g, entrance were 2.888 cm3 / g and 0.976 cm3 / g. Through the orthogonal experiments and single factor experiment systematically examines the different process parameters on the properties of activated carbon adsorption effect, get the best preparation technology parameters. The best preparation process parameters for petroleum coke activated carbon: alkali focal ratio 4:1, activation temperature 750 ℃, 2 h activation time. Black liquor activated carbon preparation process parameters for the best: coking blending ratio of 2.5:1, the carbonization temperature is 600 ℃, 1 h. carbonization time; When activated alkali carbon ratio of 3.5:1, the activation temperature of 900 ℃, the activation time of 120 min. Was studied after microwave modification of petroleum coke activated carbon on adsorption of oil and gas applications. Petroleum coke is modified by microwave method, active carbon, 90
