利用实验室规模的热解反应器来研究热解温度（300-700 ° C）对从松坚果壳的热解多联产所产生的产物的产率、质量和能量分布的影响。以生物质炭为原料，采用水蒸气活化法制备活性炭。发现范围从500至600摄氏度的热解温度在诱导具有改进的性质的产物方面是最佳的，所述改进的性质例如不凝性气体的较高热值、生物油的较低水含量和升高的热值、以及生物炭的基本固定碳含量和较大的比表面积。此外，还发现活化条件对活性炭的产率和吸附性能有显著影响。结果表明，在活化温度850 ℃、活化时间80 min、水蒸气/生物质炭比1.5的条件下，制得的活性炭比表面积可达1057.8 m2/g。(C)2016爱思唯尔有限公司版权所有。
A lab-scale pyrolysis reactor was utilized to investigate the effect of pyrolysis temperature ( 300-700 degrees C) on the yield, quality, and energy distribution of products issued from the pyrolysis polygeneration of pine nut shells. Afterward, activated carbon was prepared from biochar using the steam activation method. Pyrolysis temperatures ranging from 500 to 600 degrees C were found to be optimal in inducing products with improved properties, such as higher heating values of non-condensable gas, lower water content and elevated heating values of bio-oil, and substantial fixed carbon content and greater specific surface area of biochar. In addition, it was noticed that the activation conditions had a significant effect on the yield and adsorption performance of the activated carbon. As a result, activated carbon with elevated specific surface area reaching 1057.8 m(2)/g was obtained at the optimal conditions of 850 degrees C activation temperature, 80 min activation time, and 1.5 steam/biochar ratio.
