Abstract
Production of Hydrogen by Reaction of Pet-Al Residues of Food Bricks in the Presence of NaOH and KOH
Aymen Souilhi* and Rym Abidi
Aluminum being stacked between two layers of polyethylene in food bricks, is a source of hydrogen production highly demanded as energy in our days. With aqueous solutions of NaOH and KOH at concentrations ranging from 1 M to 10 M for T=40, 60 and 80°C, we conclude that the activation energy Ea (NaOH)=36416 J.mol-1 is lower than that of Ea (KOH) at T=60°C and a concentration of 4 M, the reaction is strongly influenced by temperature and concentration. Sodium hydroxide generally promotes more cost-effective reactions. Obtaining an aluminum hydroxide accompanied by salt (NaCl or KCl) after acid treatment of the residual alkaline solution was verified by SEM and IR, thus preserving the nature.
