Apparent kinetics of hydrogen production with water-slurried aluminum delivery in aqueous sodium hydroxide solutions

Kinetic models were fit to experimental hydrogen production data from a stirred microspherical aluminum corrosion reactor, one model for each of two Al initial conditions prior to immersion in aqueous sodium hydroxide at pH 13.17–13.48: (i) air-dry, and (ii) water-suspended for 0.5–2 h, of which the latter has not been studied. Data fitting was fairly precise (R2>0.97), and results were confirmed by comparison to shrinking core models of the...
