Diseño y construcción de un reactor para la producción de hidrógeno para el laboratorio de reacciones de la Facultad de Ciencias

Abstract

In the current context of a globalized world, a model of society that promotes sustainable energy progress in harmony with the environment is required. Fossil fuels, used as energy sources since their discovery due to their abundance and economic accessibility, generate toxic and greenhouse gas emissions that affect the environment. In order to address this problem, the present study focused on the design and construction of a reactor for the production of hydrogen by electrolysis, intended for the Reactions Laboratory of the Faculty of Sciences of the Polytechnic School of Chimborazo. First, the dimensions of the reactor were determined using various formulas and its design was carried out using the CAD software known as SOLIDWORKS. The construction of the reactor was based on engineering parameters and variables, using materials such as stainless steel, acrylic, connection hoses and flame arresters, thus ensuring its operational efficiency. The reactor had a volume capacity of 10 liters and a vessel area of 3051.06 cm2. Hydrogen production by water electrolysis was achieved by applying electric current to break down the water molecule into its components, hydrogen and oxygen. This process was carried out in an electrochemical vat. As a result, a production of 0.47 liters of hydrogen and 0.234 liters of oxygen was obtained, using a current of 16.595 Amperes during 60 seconds of continuous operation. It is concluded that the designed hydrogen reactor is efficient and capable of producing significant volumes of hydrogen and oxygen. The proper documentation and practice guide provided ensured its safe handling, thus laying a foundation for future research in the field of renewable energy.
