多元酚焦炭化料制取活性炭的研究

Abstract

Abstract: Activated carbon was prepared from polyphenol char through steam activation. Suitable technological conditions are: activation temperature 800-850℃, activation time 1.0 h for particle activated carbon and 2.5-3.0 h for granular activated carbon. The adsoption capability of activated carbon from this char is higher than that specified for activated carbon from wood used for water purification( GB/T 13803.2-1999),with iodine number >1 000 mg/g, methylene blue adsorption >12 mL/0.1 mg.It was also showed that the method of phosphoric acid activation is unsuitable to prepare activated carbon from polyphenol char.

Key words: polyphenol, char, activated carbon
