玉米芯废渣多孔碳的制备及其对液体苯的吸附
Preparation of Porous Carbon with Waste Corn Cob and its Adsorption of Benzene
摘要
Abstract
Porous carbon for absorbing liquid hazardous chemicals-benzene was prepared through chemical activation with waste corn cob as the raw material and KOH as the activator.Thermal gravimetric analysis,X-ray diffraction(XRD),and scanning electron microscope(SEM)were used to analyse the microstructure and apparent morphology of the porous car-bon.The results showed that under the conditions of 350,℃carbonization temperature,30,minutes of carbonization time, 4∶1,KOH/C mass ratio,and 120,minutes of activation time,the best activation temperature was 900,℃,the pore-forming effect of KOH was best,the porous carbons products were mainly microporous in structure,the surface area was 2,387,m2/g, and the adsorption capacity was 14,235,mg/g.关键词
