Abstract

The results of the experimental studies for «aluminum/water» chemical system are described below. The method of the aluminum activation by contact with water was examined. The kinetic of the ASD-4 and ASD-6 alloys' reaction with water at the different temperatures and in presence of the various additives was investigated. It was found that the most technological characteristics determining the rate of hydrogen production and the degree of aluminum conversation was the temperature in reaction zone, the activator's concentration, the dispersion and the composition of the aluminum alloy used. The experimental data were approximated by the equations that allow to calculate the degree of aluminum conversation at the various concentrations of lithium alumohydride for any time at a certain temperature. The kinetic characteristics of the examined reactions were also determined using the experimental data.
