The adsorption properties of microporous activated carbon prepared from pistachio nut shell for low-concentration VOCs under low-medium temperatures

Abstract: The control of low concentration VOCs in coal flue gas is one of the research hotspots at present. Activated carbon (AC) is often used as adsorbent for the control of VOCs due to its rich pore structure and thermal stability. In this paper, agricultural wastes pistachio shell was used as biomass AC raw materials, K2CO3 and KCl was used as activators. High surface area and high porosity activated carbon can be produced by the two activators used together. By comparing the differences in pore size structure and … Show more

“…Due to polar sites reduction, the water vapor adsorption decreased from 20.71 to 15.92 mmol g −1 in physisorption isotherms. [ 28 ] The water vapor adsorption isotherm of hydrophobic AC belonged to the classic type V isotherms (Figure 2b), and the shape of the hysteresis loop shrinks, which showed the interaction between adsorbate and adsorbent was relatively weak. [ 30 ] Furthermore, the adsorption energy of initial AC (74.84 kcal mol −1 ) was significantly higher than hydrophobic AC (11.82 kcal mol −1 ) for ten H 2 O molecules (Figure 2d).…”

“…32 Adsorption can occur by chemisorption, whereby the binding energy is of the same magnitude as the chemical bonds that form the substances. 33 For this reason, chemical adsorption is almost always irreversible. Conversely, the forces involved in physisorption include the van der Waals force, electrostatic and dipole polarization, and interactions.…”
