Automotive Catalyst Recycling Technology

Automotive catalyst recycling involves recovering precious metals like platinum, palladium, and rhodium from used emission control devices. These metals serve as catalysts in vehicle exhaust systems, reducing harmful emissions. Given their rarity and value, recycling is both economically and environmentally significant.

The process starts with dismantling and crushing catalytic converters to make metal extraction easier. The crushed material is then treated with acidic or alkaline solutions, such as hydrochloric or nitric acid, to dissolve the metals. These dissolved metals are precipitated through chemical methods.

Next, the metals are filtered and washed to remove impurities, and refining techniques are used to enhance their purity. The recovered metals can then be reused as industrial raw materials, contributing to environmental sustainability by reducing waste and dependence on natural resources.
