活化条件对煤质活性炭比表面积、孔容的影响

Effecct of Activtion Conditionns on Surface Area Pore Structure of Activated Carbon

我国煤的储存量大、开发制备煤质活性炭是煤炭利用的有效途径之一。讨论了同时使用水蒸汽、二氧化碳对煤进行活化时,各因素对活性炭比表面积、孔容的影响,以及比表面积与孔容之间相互的关系。在实验中制备出比表面积为1211.85 m2.g-1的煤质活性炭,为丰富煤炭资源的充分利用寻求方案。

coal capacity is rich. In this paper, the effect of activation temperature ,activation time ,water vapor and CO2 flow - rate specific surface srea and pore size distribution of activated carbon have been investigated. through water vapor, carbon dioxide,coal can be prepared surface area to 1211.85 m^2/g of activated carbon. It finds a feasible schemes of rich coal resources
