Production, characterization and methane storage potential of KOH-activated carbon from sugarcane molasses

Comparative studies of porous carbon nanofibers by various activation methods

“…The chemical activation method involves the carbonization of a raw material previously impregnated with a chemical agent. A number of different, well-known chemical agents can be used in the chemical activation process, and among them, activation using KOH and ZnCl 2 are two of the most used methods [21,22]. Chemical activation presents both advantages and disadvantages compared to physical activation.…”

Activated Carbons from Molasses as CO2Sorbents

“…It is plausible to produce AC materials from almost every organic material, with relatively high content of carbon. Choosing the right material is actually crucial factor determining ACs adsorbing abilities and its surface properties [6,7]. In recent years huge attention is turned to residual wastes and agricultural products.…”

“…Plenty of raw materials were tested as such source e.g. residual wastes and agricultural products: straw, corn straw, corn cob and hulls, eucalyptus maculata, wheat birch wood, almond shells, nut shells, sunflower shells, peanut hulls, rice hulks, husks and straw, peach pits, cherry pits, apricot pits, olive pits and residues, pine cones and needles, rapeseed, miscanthus, sugarcane * corresponding author; e-mail: jacek.mlodzik@zut.edu.pl bagasse [6][7][8][9][10]. Using such unusual material is a challenge, because preparation procedure, activating agent, physical and chemical properties of starting materials can influence the textural properties of ACs [11].…”

“…Up until now, molasses has been considered as such carbon source just twice [6,12], and it has been proven as very promising material to study. Results of this study was AC able to adsorb 11.76 mmol/g of CH 4 at 40…”

Comparative study on microstructure and surface properties of keratin- and lignocellulosic-based activated carbons

“…For chemical method, the precursor is mixed with compounds such as phosphoric acid [4], potassium hydroxide [5], zinc chloride [6] and potassium carbonate [7] and [8], and then activated at various temperatures. The previous studies [9] have been reported that carbon activated by potassium hydroxide could possess high specific surface area and large number of micropores, but the apparatus would be corroded and the life of which lowers due to the strong basicity.…”
