Preparation of high-surface area activated carbons from Paulownia wood by ZnCl2 activation

Removal of CO2 in a Multi Stage Fluidized Bed Reactor by Monoethanolamine Functionalize Activated Carbon

“…Table 1 shows the data related to total surface area, micropore volume and micropore surface area for amine impregnated activated carbon particle, activated carbon particle and raw precursor. Fig.1 shows the N2 adsorption isotherms and it is of Type I, which represents dense micropore structures [12]. The schematic diagram of four-staged fluidized bed reactor has been shown in Fig.…”

A New Activated Carbon Prepared from Sago Palm Bark through Physiochemical Activated Process with Zinc Chloride

“…As shown in Table 1, SPB was found to have ash low content (1.53%), this make SPB is the best choice for AC preparation and production [29]. To calculate the production yield of the precursor, the mass of AC is divided by raw material initial mass that was utilised for activation [42].…”

“…This results into the destruction of the cellulose structures. Tar formation is inhibited and carbon yield is increased by the chemical activation of the agents [28,29]. Several researchers have made use of ZnCl2 for the chemical activation step of the AC preparation.…”

Activated Carbon Prepared From Orange Peels Coated With Titanium Oxide Nanoparticles: Characterization and Applications in the Decomposition of NOx

“…The sample was degassed at 250°C under a vacuum for 4 h. The apparent surface area of nitrogen was calculated using the BET (Brunauer-Emmett-Teller) equation within the 0.01-0.3 relative pressure range. The micropore volume was determined according to the DR (Dubinin-Radushkevich) method [31][32][33][34] . The amount of N 2 adsorbed at relative pressures near unity (~0.99) corresponds to the total amount adsorbed in both micropores and mesopores; consequently, the subtraction of the micropore volume from the total amount will provide the volume of the mesopores.…”

“…The XRD pattern and data were also analyzed using the Powder X program [35][36][37][38][39] . From these XRD patterns, the crystallite or grain size (d XRD ) of the prepared powders was estimated using the Scherrer equation (Eq.1) as follows 10,[33][34][35] :…”
