A Study of the Impact of Power Supply Parameters on Metal Flow Velocity in the Channel of a Device for Washing out Precious Metals from of the Automotive Catalytic Converters

Abstract: The lifetime of a catalytic converters is limited. Today's environmental regulations require that used converters should be properly recycled as a valuable source of precious metals, Al 2 O 3 and steel scrap. The precious metals used in the devices perform catalytic functions. They are suspended in a ceramic or metal carrier. This paper deals with the recovery of precious metals from automotive converters using a metal-collector method. In order to speed up the washout of the precious metals from the capillary… Show more

“…It was assumed that the air mass flows in all tubes of a specific module were balanced. More complicated procedures occur during energy recovery at other metallurgical processes [17,18]. Calculations of the temperature distributions for exhaust gases and air in the module tubes were performed according to the methodology presented in the paper [14].…”
