以煤炭为原料制备活性焦及其脱硫效应的研究

A STUDY ON PREPARATION OF ACTIVATED COKE FROM COAL AND ITS DESULFURATION PERFORMANCE

以普通煤为主要原料制备了活性炭类吸附剂——活性焦。实验对其进行了性能测试并研究了吸附时间和吸附温度对产品脱硫效率的影响。结果表明 ,制备出的活性焦成本低 ,脱硫效率高 ,再生性能和机械性能良好 ,可用于大气中污染物 SO2

The present paper aims at studying the usability of the activated coke in desulphuration and the behavior of its absorption of SO 2 through the corresponding experiments. It is proved from the experiments of ours that the activated coke can reproduce by using the method of water vapors as the result of fine reproduction. Under certain technical conditions, such as in ideal raw material proportion, carbonization and activation, it is possible to develop a kind of activated coke mainly from ordinary coal efficiently and economically with high desulphuration efficiency, fine reproduction and proper technical properties.
