Optimal temperatures for catalytic regeneration of activated carbon

Comparative Study of the Adsorption from Aqueous Solutions and the Desorption of Phenol and Nonylphenol Substrates on Activated Carbons

“…Several researchers (24,(35)(36)(37) have investigated the thermal desorption of phenolic compounds in an inert atmosphere. According to those authors, part of the phenol was desorbed at low temperatures, below 500 K (physically adsorbed).…”

Carbon materials and catalytic wet air oxidation of organic pollutants in wastewater

“…Examples of such new concepts are the simultaneous adsorption and oxidation [26][27][28][29] or sequential adsorption-oxidation [30] of pollutants as well as adsorptionregeneration cycles in the same reactor unit [31][32][33][34]. Better performance of a continuous trickle bed reactor (TBR) for the phenol CWAO was also achieved by applying forced periodic operation of liquid flow [35].…”

Surface modified activated carbon with β-cyclodextrin – Part I. Synthesis and characterization

“…Water molecules adsorbed in the micropores of AC and in the cavity of β-CD may be desorbed at higher temperatures above 150 • C, as explained by Matatov-Meytal et al [33] and Haydar et al [34] The GA linker was desorbed after cleavage of the covalent bond between AC and β-CD as evidenced by the greater T m (maximum temperature of decomposition). Carboxylic acids and carbonyl groups may undergo decarbonylation reactions forming CO 2 and CO of C=O and C-O functional groups including hydroxyl groups as similarly concluded by Figueiredo et al [35] β-CD was desorbed from the surface of AC after cleavage of the covalent bonds between the linker and β-CD.…”
