Different Supercapacitive Behavior of Two Glucose-derived Microporous Carbons: Direct Pyrolysis versus Hydrothermal Carbonization

This work compares for the first time the physical and chemical characteristics of activated carbons produced from glucose and hydrothermally carbonized glucose, as well as their performance as electrodes in supercapacitors in aqueous electrolyte (H2SO4). Both KOH-activated carbons exhibit similar textural properties, with BET surface areas of ~ 1400-1500 m/g and a pore volume of ~ 0.70 cm/g, t...

Impact of the Carbonization Atmosphere on the Properties of Phosphoric Acid-activated Carbons from Fruit Stones

Activated carbons were obtained by phosphoric acid activation of a mixture of fruit stones (apricot and peach) in two different atmospheres (argon and air) at various temperatures in the 400–1000oC range. The evolution of several characteristic parameters of the resulting carbons (bulk density, yield, BET surface area, ultramicropore, supermicropore and mesopore volumes and cation-exchange capa...

Physicochemical, Pyrolytic, and Combustion Characteristics of Hydrochar Obtained by Hydrothermal Carbonization of Biomass

Effects of the type of biomass and temperature, with longer residence time, on physicochemical characteristics of hydrochar were investigated. Different carbonization conditions were applied with the goal of producing hydrochars having better physicochemical properties. After the carbonization process, the pyrolysis and combustion behaviors of hydrochar were evaluated. The effect of temperature...
