Dear sir,

There are two kinds of Platinum catalysts, monometal platinum catalyst and thermometal(platonic
rhenium, platonic stannum) . The carrier of platinum catalyst in chief is Alumina and oxygen (Chem name is (AL2O3) , the constituent of it is over 99%. In a platinum catalyst, the content of platinum is between 0.1%--0.6% per ton.
But we need the used one, it mean after chemistry reactivity, the same mean it is the recycle one.
If you have you can inform me immediately, we want to buy large quantity.
