Sustainable Biodiesel Reactor Prototype Energetically Powered By Solar Energy
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 2
Abstract
The study of routes aiming the implementation and use alternative energy sources has increased exponentially during the last decades, due to reduction of petroleum reserves and environmental damage related to fossil fuels use. In this context, biodiesel appears as a potential substitute for diesel, however, because of its economic non-competitiveness, there is still an obstacle to a greater use of this fuel. Alternatives for operational costs reduction on biodiesel production process, most commonly carried out by methyl transesterification, rely on solar energy use to generate electricity and obtain heat for chemical reaction needs. This work presents the design, dimension and construction process of a sustainable biodiesel reactor powered energetically by a solar collector constructed with recycled materials, such as polyethylene terephthalate (PET) bottles, and electrically powered by a photovoltaic system. The solar radiation and photovoltaic study was made considering the electrical consumption forecast. Tests were carried out to verify the chemical reaction heat transfer and the electric circuit operation in order to verify the prototype reliability. The final product was evaluated using gas chromatography technique showing that the produced biodiesel presented 97.6% in ester contents, bigger value than the recommended by European Committee for Standardization and the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP).
