微波法稻壳制备活性炭研究

Preparation of activated carbon from rice husk by microwave method

稻壳是稻米加工后产生的大宗农业废弃物,高效、高附加值利用稻壳,对促进循环经济发展具有重要意义。以稻壳为原料,氯化锌为活化剂,采用微波处理,制备出微细孔发达的商业级活性炭。微波法生物质制活性炭,加热时间短,能耗低,是具有商业前景的绿色化学工艺。

Rice husk （RH） is the agricultural waste produced during rice processing. It＇s meaningful for circulareconomy development to use RH efficiently with high added-value. A microwave preparation technology ot commercial activated carbon with miniature holes was introduced, taking rice husk as raw material and ZnCl2 as the activating agent. This technology is a promising green chemical technique with short heating time and low energy consumption.
