Abstract
The Chemical Industry has been increasingly looking for clean, renewable and sustainable technologies. The automotive industry, in particular, has been looking for solutions that make the vehicles of the future no longer dependent on fossil fuels. One of the technologies that has been developed is related to fuel cells that use hydrogen as fuel. Currently, the forms of hydrogen production in the chemical industry continue to use fossil fuels such as natural gas and naphta or production from electrolysis of water. This work will present the production of hydrogen from the spontaneous chemical reaction between recycled aluminum and sodium hydroxide. The system takes in consideration the knowledge of heat and mass transfer, mass and energy balances, heterogeneous reactors, thermodynamic of solutions, refrigeration and science of materials. The reaction is exothermic and the reactor will be operated isothermally. From data obtained by conductometric method and mathematical modeling of the system will be possible to predict the behavior of the reaction. The expected results are the hydrogen production and the validation of the kinetic proposed. Graphs of conductivity x time and the consumption of sodium hydroxide x time will be obtained to analyze and to confirm the order of the reaction.
