3.By varying glycol; porouscarbon with narrow pore size distributions can be obtained and the average pore size of porouscarbon is between 0.01 and 5μm, with BET surface area range from 350 to 400m2·g-1.
7.The specific surface area of activated carbon is 1 254.51 m2/g by BET method. The porous structures of the activated carbon were investigated by density function theories(DFT). It shows that the activated carbon is microporous with 0.592 6 mL/g for total pore volume.
8.The results show that at 10 ℃, the adsorption capacity of cross-linked chitosan porous microbeads for Orange Ⅱ is 4.39, 6.68 times of reactive carbon and chitosan respectively, the adsorption velocity is 2.58 times of chitosan.
9.Chemically activated carbon, of which the BET surface area is 3886 m 2/g and the micro porous volume 1 82 ml/g, was produced at the conditions of 830 ℃ activation temperature, 1.5 h activation time, 6∶1 of alkali /carbon and 100～154 μm particle size.
10.The paper discussed that Silicon-nitride based porous ceramic was prepared by reaction-sintering and pressless-sintering with the powder of Si as raw material, Al2O3 and Y2O3 as sintering aids, carbon and carbamide as pore-forming agent.
