摘要

A simultaneous “hydrodynamic cavitation - high voltage discharge in water” (HCHVD) procedure used for recycling platinum group metals (PGM), such as Pd and Pt, found in three-way catalyst converters is presented. During hydrodynamic cavitation high shear forces was provided by using a nozzle with a throat diameter of 0.2 mm. A pressure of 60 MPa was obtained by using a piston pump. For the first s...
