There is rule of thumb for catalyst loading in the FMC paper. They
worked with silver and 85% peroxide, and they found that above a
certain value of lb/sec of peroxide per in^2 of catalyst, they flooded
the catalyst. I forget that number, but since it's forty years old,
fairly readily available, and has been discussed here before, we can
certainly post it again to save Ben a search through the archives.
The same information on ERPS' cermet catalyst would be proprietary and
inappropriate for a public list. If we knew what it was. :-) All we
have yet a lower limit, a value at which the engine does not flood,
which is rather lower than the upper limit for the equivalent catalyst
bed of silver.
AFAIK, the whole area of catalytic activity is poorly understood in
terms of physical chemistry. The answers to your questions may not
exist anywhere. Which for an engineer is damn frustrating, but for a
scientist is pretty exciting. "LOOK! A research topic! Thankyou
thankyou thankyou...."
