Preparation of monolithic activated carbon foam and its adsorption characteristics for acetone
泡沫活性炭的制备及其对丙酮的吸附性能研究

Monolithic activated carbon foam (MACFoam) with BET surface area about 672 m2/g and highly developed mesopores was obtained from mesophase pitch and coal. It was prepared by foaming process at high temperature and pressure, carbonization and steam activation. There are a lot of micron-sized interconnected pores in the MACFoam which can permit gases pass through. Its adsorption behavior for acetone in fix bed is similar to that of granular activated carbon and the Yoon-Nelson equation can be applied to treat the experimental breakthrough curves of acetone.
