An investigation on the preparation of active carbon-ceramic sphere

摘要：

A procedure for the preparation of active carbonceramic sphere was developed.Active carbon-ceramic sphere were prepared by coating a porous ceramic sphere with a phenolic resol resin (carbon precursor).The following procedure was adopted: (a) impregnation of the ceramic substrate with phenolic resol resin; (b) curing; (c) carbonization; (d) activation with KOH etching; (d) washing and drying. Under the optimal impregnation conditions, the material obtained (PRR 70 ％) at 30°C, which exhibited a high carbon percentage (~ 5.3 wt.％) with a total pore volume of 0.276 cm3g-l and a specific surface area of 471 m2g-l (carbon in the carbon-ceramic sphere) by N2 adsorption, respectively.By means of chemical activation (KC-120), the total pore volume increased to 0.69 cm3g-l and the specific surface area to 1110 m2g-l (carbon percentage: 4.73 wt.％), respectively.The activated material shows a uniform carbon distribution, good adsorption properties and a high mechanical strength (24MPa).
