水蒸气活化法制备分子筛炭织物的前驱体

PREPARING THE PRECURSOR OF CMS BY H_2O ACTIVATION METHOD

以PAN系预氧毡为原料，在惰性气体N2中炭化后，用水蒸气活化制取分子筛炭织物的前驱体活性炭毡。考查了活化时间、升温速率对活性炭毡吸附性能的影响，并用DFT法、D－A法、H－K法表征其微孔结构。

The PAN-based preoxidated felt as raw materials was carbonized in N2 atmosphere, then was activated by vapor of H2O to abtain the precursor (activated carbon felt) of CMS. The effect of activated time and the rate of raising temperature on adsorption properties of the activated carbon felt was examined. Its pete structure was characterized by the motheds of DFT, D-A and H-K.
