Abstract
It is known that fossil and non-renewable energy sources are abundant and must remain in use for many years. However, the necessity to diversify the energy matrix and the search for renewable and environmentally more appropriate sources of energy are objectives that are necessary and even urgent. Ethanol, biodiesel and biogas are the target of the main researches that approach this subject. However, recently, other renewable energy sources have been gaining prominence in the scientific field and in several specialized studies, such as hydrogen. Hydrogen is a type of clean energy that can be produced in a number of sustainable ways, such as from aluminum scrap. This article proposes the development of a mathematical model of a reactor with the purpose of producing hydrogen through recyclable aluminum. The mathematical model was developed based on the model proposed by Noland et al. (2020), which includes the kinetics of the balanced chemical reaction of H2 production from aluminum scrap that occurs inside the reactor. Next, the mathematical model was implemented in a computer program and initial numerical results were obtained to be compared to experimental data. Through the results and graphs obtained, it was considered that the kinetics of the hydrogen production reaction was modeled mathematically in an adequate way. The next step will be to use the model to control and optimize the H2 generation reactor. Different proposals for the geometric and functional design of the system will be considered and tested with the mathematical model in terms of materials, reagent supply, waste collection and H2 output to the H2 storage tank, which will be compared in terms of objective functions suitable for the system (such as mass yield, size and weight). This article will demonstrate the first results obtained for the proposed system.
