| 中文摘要 |
| 以木炭或煤为辅助原材料,采用预活化工艺,将炭酸水洗后,经活化或二次活化后制成颗粒活性炭。成品炭碘值为600-700mg/g.在工业性试生产中,新生产的活性炭碘值为630-800mg/g,耐磨强度超过95%,从而为粉煤灰综合利用开辟了新途径。 |
| 英文摘要 |
| A production process of activated carbon in which the carbon in a coal ash from a power station was used as a starting material has been developed.The optimized conditions for this process to produce a granular activated carbon were using charcoal, white charcoal or coal as an auxiliary raw material,together with which the starting material was undergoing a treatment in a preactivation process,then was washed with acid and water,and finally was activated or even further reactivated if required.The activated carbon product thus produced had an iodine value of 600-700 mg/ g.The activated carbon from a pilot industrial production had an iodine value of 630-800mg/g with a wearability of over 95%.This process provides a new way for coal ash to be utilized comprehensively. |
