Findings from Babol University of Technology Provide New Insights into Chemical Engineering

May 14, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators discuss new findings in Chemical Engineering. According to news reporting from Babol Sar, Iran, by VerticalNews journalists, research stated, "A series of activated carbons (ACs) were prepared from Eucalyptus camaldulensis wood by chemical activation with H3PO4, ZnCl2 at different impregnation ratios as well as by pyrolysis, followed by activation with KOH. The porosity characteristics of these ACs were determined by N-2 adsorption isotherms."

The news correspondents obtained a quote from the research from the Babol University of Technology, "Through varying the H3PO4/biomass ratio from 1.5 to 2.5, the prepared ACs displayed BET surface areas in the range of 1875-2117 m(2)/g with micropores content of 69-97%. For the ZnCl2 activated series, BET surface areas varying from 1274.8 to 2107.9 m(2)/g with micropores content of 93-100% were obtained from impregnation ratios of 0.75-2.0. The AC obtained by KOH had the largest BET surface area of 2594 m(2)/g and the high micropore content of 98%. In addition, the FTIR and SEM analyses conducted for characterizing the ACs and the CO2 adsorption onto all series of the eucalyptus wood based ACs at pressures ranging from 0 to 16 bar using a volumetric method were investigated. Also the effect of temperature (15-75 degrees C) on the amount of CO2 adsorbed by the ACs that was prepared with H3PO4, KOH and ZnCl2 was studied."

According to the news reporters, the research concluded: "The CO2 adsorption capacity on the AC prepared with KOH was up to 4.10 mmol/g at 1 bar and 303 K, having an increase of about 63% in comparison with the commercial AC."
