Recover precious metals from spent catalysts

Here are guidelines for maximizing the reclamation of valuable byproducts to ensure the highest possible return on investment

Beirne, K. M., Sabin Metal Corp.

Precious-metal-bearing catalysts, particularly those containing platinum group metals (PGMs)—such as platinum, palladium, rhodium and ruthenium—play a vital role in the hydrocarbon processing industry, both for facilitating or speeding chemical reactions and for end-of-pipe emission control (Fig. 1).   Fig. 1    A typical hydrocarbon processing refinery uses PGM-bearing catalysts. For example, catalysts containing platinum are used in refining crude oil and producing various aromatic compounds. Catalytic reforming uses palladium on an alumina base to produce high-octa
