Estudo teórico de sistema para produção de carbono nanoestruturado em larga escala utilizando resíduos plásticos como precursores

Abstract

Plastic waste has become a worldwide concern in recent years due to its large volume of annual production combined with the low percentage that is correctly destined after consumption. In this scenario, the application of these materials as precursors in the synthesis of nanostructured since these materials have a great applicability and has been expanding its large-scale production to meet the needs of the market. Therefore, the present work aimed to conduct a study of the processes and raw materials needed in the production of nanostructured carbon materials, as well as to search for optimized operating conditions that contribute to its large-scale production using plastic waste as carbon precursors. The method used to obtain the theoretical framework was based on RBS and the selected publications made it possible to propose a large-scale process to produce carbon nanomaterials, using plastic residues as precursors. It was concluded that to maximize the production of these materials should use a process composed of 3 stages, pyrolysis of plastic waste, separation of pyrolysis gases and synthesis of nanostructured materials, each of the steps has its operational parameters individually defined to have better control over the operation.
