Preparation and characterization of activated carbon from bagasse fly ash

Evaluation of Press Mud, Vinasse Powder and Extraction Sludge with Ethanol in a Pyrolysis Process

“…The results of the fixed carbon, oxygen, and carbon are also higher for the powder vinasse with respect to those of the press mud and those of the extraction sludge, which indicates better yields of the powder vinasse either to form bio-char or solid fuels. The high content of oxygen and carbon suggests the presence of organic groups characteristic of lignocellulosic materials [22]. On the other hand, the sulfur and nitrogen values of both press mud and powder vinasse are low, being consistent with values reported in the literature [34,35].…”

“…Previous studies have shown the feasibility of using pyrolysis for sugarcane bagasse, demonstrating that the bio-oil can be potentially valuable as a renewable fuel and can be used as a chemical feedstock [17,18], while the bio-char can be used as a solid fuel, a cheap adsorbent, feedstock for activated carbon production, and in agricultural applications [19][20][21][22]. However, studies for press mud [23,24] and vinasse [25,26] pyrolysis are scarce.…”

Adsorption of phenol and methylene blue from aqueous solutions by pyrolytic tire char: Equilibrium and kinetic studies

“…Helleur et al [37] found the sorption capacity of 400 post-carbonized at 600 C char for MB of 35 mg g À1 . Overall, it can be noted that all Freundlich K f values and Langmuir capacity values reported in the above studies are 403 significantly lower than that found in the present study, probably 404 due to the acid treatment of char, as well as, pyrolysis conditions.Comparison with other pertinent adsorbentsYerner et al[43] studied the sorption of MB onto Norit SA3 powdered activated carbon and Nuchar WWH granulated 408 activated carbon and assuming a Langmuir isotherm, they 409 estimated sorption capacities of 91 and 21.5 mg g À1 , respectively.In addition, Wang et al[44] have found adsorption capacities of 411 177.7 and 217.3 mg g À1 onto Calgon's coal based F100 activated 412 carbon and coconut shell-based activated carbon, respectively.Finally, adsorption capacities of 323 mg g À1 for Norit GAC, 414 263 mg g À1 for Norit SX plus, 299 mg g À1 for Filtrasorb400 and 415 246 mg g À1 for Picacarb were found elsewhere[45][46][47].With regard to phenol, adsorption capacities of 128 mg g À1 for Norit SX plus, and 35 mg g À1 for Norit SA3 were reported[37,46].…”

Two Unconventional Precursors to Produce ZnCl2‐Based Activated Carbon for Water Treatment Applications

“…Currently, coal is the major starting material to produce AC, however, it is relatively expensive, non‐renewable, and a highly structured material that could be used for energy generation instead of pollution control applications , . Therefore, it is important to find new low‐cost, renewable materials to replace the conventional AC precursors.…”
