ball mill for spent automotive catalysts

Oct 31, 2019 Ferdi Sch th’s research team analyzed whether a catalytic reaction in such a ball mill actually works better, since the catalyst is invariably given a fresh surface where the reactants can meet. The researchers applied soft alumina, or gamma-alumina, combined with gold particles as a catalyst, and tracked the process in the ball mill through ...
