Removal of water pollutants with activated carbons prepared from H3PO4 activation of lignin from kraft black liquors.
Activated carbons with a high BET surface area and a well-developed porosity have been prepared from pyrolysis of H3PO4-impregnated lignin precipitated from kraft black liquors. Impregnation ratios within the range of 1-3 and activation temperatures of 623-873 K have been used, giving rise to carbons with different porous and surface chemical structure. Increasing the activation temperature and...
متن کاملRemoval of Pollutants with Activated Carbon Produced from K2CO3 Activation of Lignin From Reed Black Liquors
The activated carbon was prepared from fast precarbonization of reed lignin in the fluidized-bed followed by K2CO3 activation. The impregnation ratio was = 1:1 in this research. The effect of activation temperature upon the BET specific surface area and specific pore volume of the carbon was closely investigated. Increasing activation temperature led to an opening and widening of the porous str...
متن کاملPreparation of Activated Carbon from Lignin Obtained by Straw Pulping by Koh and K2co3 Chemical Activation
Activated carbon was prepared through chemical activation of lignin from a straw pulping precursor, using K2CO3 and KOH as chemical agents. To optimize the preparation method, the effect of the main process parameters (such as impregnation ratio, activation temperature and activation time) on the performance of the obtained activated carbon (expressed in terms of iodine number and yield of acti...
متن کاملPreparation and Characterization of K2CO3-Activated Kraft Lignin Carbon
A series of activated carbons (ACs) were prepared by K2CO3 activation from kraft lignin (KL) that was recovered from papermaking black liquor. The effects of process parameters such as the activation temperature (AT), activated period, K2CO3 to KL mass ratio, and N2 flow rate on the characteristics of the final product were determined. The ACs were characterized using nitrogen adsorption, morph...
متن کاملOptimization of Pb(II) Adsorption onto Australian Pine Cones-Based Activated Carbon by Pulsed Microwave Heating Activation
This study proposed a novel method for preparing activated carbon from Australian Pine cones (APCs) to optimize Pb(II) adsorption. Based on an analysis conducted, the APCs dried powder consisted of approximately 51.32 wt% of cellulose and 21.15 wt% of lignin on average. Experiments in batch mode at 100-rpm stirring speed, pH 4.7 (± 0.3) and 27 oC (± 2 o</su...
