成型活性炭的制备及其甲烷吸附性能的研究

The preparation and methane adsorption performance of formed activated carbon (FAC) prepared using carboxymethyl cellulose as a binder and powdered activated carbon with BET surface area of 2325m2/g as raw material were investigated. The orthogonal experiment indicated that the descending order of factors influencing the properties of the FAC is as follows: molding pressure > heat treatment temperature > heat treatment time > ratio of binder. The optimum condition to obtain highest volumetric methane uptake of 167.9 at 298K and 3.6MPa is 62.5MPa, 250℃, 90min and 20% for molding pressure, heat treatment temperature, heat treatment time and ratio of binder respectively.
