神府煤及其镜质组对制备炭吸附材料并联产氢气影响的实验研究

摘要

Taking Shenfu coal as the research object,the experiment studied the effects of different activation temperature on the performance of coal-based carbon adsorption materials prepared from Shenfu coal and hydrogen co-generation.In addition,the study was made on the adsorption abilitY,morphological property and gaseous product composition of carbon adsorption materials made from Shenfu coal vitrinite of different enrichment ratios under the activation temperature of 7 00 ℃.The results showed that,with the increase of activation temperature,the adsorption value of carbon material would first increase and then decrease.Under the activation temperature of 700 ℃,it was found that the adsorptive property of carbon material was good.During the activation process of Shenfu coal vitrinite,at the activation temperature of 700 ℃,the content of co-generated hydrogen would increase with the increase of the enrichment ratio of the vitrinite.%以神府煤为研究对象,通过实验考察不同活化温度对神府煤制备炭吸附材料性能和联产氢气的影响,并研究了在活化温度为700℃时,不同富集率的神府煤镜质组所制备的炭吸附材料吸附性能、形貌特征及气相产物成分.结果表明,随着活化温度的升高,神府原煤制备的炭吸附材料的吸附性能先增大后减小,活化温度为700℃时,制备出的炭吸附材料吸附性能较好;神府煤镜质组活化过程中,活化温度为700℃时,联产氢气含量随着镜质组富集率的增大而增大.
