摘要
以木糖醇渣为原料,磷酸为活化剂制备新型粉状活性炭。考察了磷酸浓度、活化温度、活化时间,以及原料含水量对产品性能的影响。开辟了制备活性炭的一种新途径,并可废物利用,增加经济效益。
A new type powdery activated charcol was preduced from xylitol residue with phosphoric acid as activating ngent. The effects of phosphoric acid concentration, activating temperature, activating time and moisture content of materials were studied. A new way of preducing activated charcoal was invented. This method utilizes waste rnaterial and economic benefit is improvd.
