The Potential of Activated Carbon Made of Agro-Industrial Residues in NOx Immissions Abatement

[...]the interest in adsorptive cabin air filters and HVAC (Heating, Ventilation and Air Conditioning) filters is rising. [...]the phosphoric acid acts as an acid catalyst to promote bond cleavage and formation of cross-links via cyclization/condensation reactions. [...]the AC-H3PO4 carbon shows the highest nitrogen uptake at −196 °C, thus displaying the highest surface area and the best-developed porosity. [...]these activated carbons have quite similar textural properties but the adsorption capacity for AC-H2O (CNO2 = 16 mg/g) is slightly higher than AC-CO2 (CNO2 = 14.4 mg/g).
