Abstract
A technique for recovering palladium from a spent palladium catalyst or ash thereof involves fluorinating the catalyst or ash at elevated temperatures to yield palladium fluoride and decomposing the fluoride with a mineral acid at a temperature ranging from 90.degree. - 100.degree. C.
Claims5
A method for recovering palladium values from spent palladium catalysts and ash thereof which comprises the steps of fluorinating the spent catalyst and ash at a temperature which increases gradually from 200.degree. - 500.degree. C and decomposing palladium fluorides so obtained with a mineral acid at a temperature ranging from 90.degree. - 100.degree. C to obtain palladium values in solution.
