HYDROGEN GENERATED BY THE OXIDATION OF ALUMINUM IN A LOW CONCENTRATED AQUEOUS POTASSIUM HYDROXIDE SOLUTION UNDER VIGOROUS STIRRING

This work is devoted to development of scientific and technological bases of creation of the power plant. The aluminum used as fuel, and an oxidizer - low concentrated aqueous potassium hydroxide solution. In this paper a study was conducted of the oxidation of particulate (granules and particles) of aluminum in aqueous potassium hydroxide solution with a relatively low values, while the impact on the mechanical mixing reaction space. Experiments were conducted under these concentrations of alkali and stirring speeds, which in themselves would not lead to signif-icant rate of oxidation and the degree of conversion of aluminum. The aim of this work is to establish synergies between the two types of activation. The objectives is to establish the degree of conversion depending aluminum (yield hydrogen) on parameters such as the volume ratio of aqueous solution to the weight of alumina (α), the concentration of alkali in solution form aluminum particles, agitation speed, as well as chemical purity of the starting reactants.
