Abstract

Microporous activated carbons were prepared from date pits using thermal activation with CO2 or steam. The adsorbents were characterized by N2 and CO2 adsorption at 77 K and 273K, respectively. The H2 adsorption was measured at 298K and 100 bar using a volumetric equipment. To increase the hydrogen storage, activated carbons are doped by metals. The results show that the H₂ adsorption capacity is influenced by the size and volume of micropores in the activated carbon adsorbent. A relationship between hydrogen adsorption capacity calculated using Langmuir isotherm and the volume of narrow micropores deduced from the CO2 adsorption isotherm at 273 K was found. A correlation was also found between both micropore volumes and the amount of hydrogen adsorbed at 298 K and 100 bar. Additionally, vanadium doping of activated carbons could positively influence hydrogen adsorption.

N2 - Microporous activated carbons were prepared from date pits using thermal activation with CO2 or steam. The adsorbents were characterized by N2 and CO2 adsorption at 77 K and 273K, respectively. The H2 adsorption was measured at 298K and 100 bar using a volumetric equipment. To increase the hydrogen storage, activated carbons are doped by metals. The results show that the H2 adsorption capacity is influenced by the size and volume of micropores in the activated carbon adsorbent. A relationship between hydrogen adsorption capacity calculated using Langmuir isotherm and the volume of narrow micropores deduced from the CO2 adsorption isotherm at 273 K was found. A correlation was also found between both micropore volumes and the amount of hydrogen adsorbed at 298 K and 100 bar. Additionally, vanadium doping of activated carbons could positively influence hydrogen adsorption.
