Process for separating and recovering metal catalysts

A process is provided for separating and recovering solid, metal catalysts from reaction mixtures in which they are dispersed, with cross-flow filtration using membrane separation devices. The process is particularly useful for separating gelatinous catalyst sludges, e.g., nickel hydroxide, used in...

Zusammenfassung:	A process is provided for separating and recovering solid, metal catalysts from reaction mixtures in which they are dispersed, with cross-flow filtration using membrane separation devices. The process is particularly useful for separating gelatinous catalyst sludges, e.g., nickel hydroxide, used in oxidizing diacetone sorbose.
