Aspectos de sustentabilidade em um processo de produção de hidrogênio com a reutilização do alumínio

Abstract

Taking into account measures to reduce the effects of climate change and technologies that help energy security, this dissertation focuses on the study of generation of hydrogen gas as alternative energy. Hydrogen gas is an energy vector with reduced emissions of pollutants into the atmosphere compared to existing traditional sources of energy. However, studies and research on their potentialities and viabilities, both technical and socioeconomic and environmental, need to be developed for technological maturation. The objective of this dissertation is to analyze the production of hydrogen by alkaline hydrolysis, with the reuse of aluminum, correlating it to the aspects of sustainability. It starts from a process already known and well diffused in the scientific environment which will be analyzed and discussed its possibilities as alternative technology for energy production. The method used for the analysis was bibliographic along with the collection of primary data in the laboratory of a process with patent application, giving character of exploratory and descriptive research. The main technical results were: average flow 77.53 ml (min.g) -1 .H2, with a purity of 84.20%. Then, an economic analysis was performed in national currency, real R $ / (m³.H2) and US$ / kWh, comparing with other studies that determined the cost of production in this type of generation processes. gas. A matrix of aspects and impacts was drawn up illustrating the potential effects on energy generation. It was concluded that the generation of hydrogen gas by alkaline hydrolysis with the reuse of secondary aluminum contributes to the vision aimed at the sustainability of the planet, and can be a decentralized energy alternative.
