Recycling of the platinum of vehicle catalysts at end of life 2018-36-0106

Due to the large number of end of life vehicles in our country, our work is aimed at recycling a very important material present in all cars, which is the platinum found in automotive catalysts. Platinum is a rare metal and high value-added, recovery from secondary sources is crucial to ensure its supply for various applications in the market, especially in regions with scarce resources. For this reason, the recycling of platinum, particularly of automotive catalysts becomes very important for the market. The methodology to be applied along the development of the work approaches from the characterization of the catalyst (by technical analysis of microscopy), recycling of platinum (by hydro-metallurgical processes), finally the tests and analysis of the recycled platinum, through physical tests, chemicals. Through the platinum recycling process, it is expected that an economically feasible form has been determined as well as the process method for platinum recycling, in addition to achieving a sample of recycled platinum with physical and chemical characteristics that provide for its reuse. However, the process of recycling platinum comes as an ecological alternative for the extraction, and through this research they propose a recycling method to return it to the market, suppressing its scarcity.
