How does product number 205699, Palladium on Carbon, differ from 330108, which is also 10 wt % palladium on activated carbon?
Product number 330108 is the wet support and appears as a moist black powder.  Product number 205699 is dry.
Is Product 205699, Palladium on carbon, reduced or unreduced?
It is reduced, but it can oxidize pretty readily.
What is the particle size of Product 205699, Palladium on carbon?
We expect the product to conform to the following: approximately 90% <60 µm and 10% <5 µm with an average particle size of 15 µm. 
What is the activity of Product 205699, Palladium on carbon?  How is the activity tested?  Is it a guaranteed value?
There is a fairly large variance in activity reported by the manufacturer on this material (from less than 50 ml/min to more than 100 ml/min).  Activity is not a specification but reported on the Certification of Analysis for further information.  Activity is measured by the hydrogen reduction of nitrobenzene. 
What is the surface area of Product 205699, Palladium on carbon?
The surface area of the carbon used as the support is 750-1000 m2 /g.  They do not test the surface area of the finished catalyst.
