A set of aluminum dross hydrolysis hydrogen production equipment was experimentally designed and installed. The effects of reaction temperature, liquid volume to solid mass ratio, stirring speed, and aluminum dross particle size on the aluminum dross hydrolysis hydrogen production process were studied, and the kinetics of the aluminum dross hydrolysis hydrogen production process were explored. The results show that the optimal process conditions for aluminum dross hydrolysis hydrogen production are reaction temperature of 85 ℃, liquid volume to solid mass ratio of 10 mL/1 g, and stirring speed of 130 r/min, aluminum dross particle size of >80 mesh. The main phases of the hydrolysis residue obtained under optimal conditions are MgAl2O4, Al(OH)3 and Al2O3. The hydrogen production process from aluminum dross hydrolysis is controlled by chemical reactions, with a chemical apparent activation energy of 67.01 kJ/mol. The leaching process follows the Avrami-Erofeyev model. The experimental results can provide certain technical references for the design of aluminum dross hydrolysis hydrogen production process.
