Why assume screens? This sounds like it would lend itself to winding
catalyst-clad wire under tension in a criss-cross pattern around the
central perforated tube.
If you want further compression, size things so that heating the outer
tube and cryo chilling the wire-wound inner tube before assembling them
makes them a tight fit.

Robert,
It sounds like the Condor had axial flow from top to bottom. I think
what Paul is suggesting is radial flow from inside to outside with a
solid bottom plate and a perforated side wall letting the flow out into
a surrounding chamber.
I think Paul's idea has a lot of potential. One issue with it is
pre-compressing the screens. With axial flow you can press them down
with a hydraulic press. How can you pre-compress the screens radially
from inside to outside?

That is the way the Condor cat pack was made except we injected from
the top. We tried center injection but the
peroxide never got to the outer screens so we went back to top
injection. No channel rings cause the screen
is tight against the wall of the catpack.

Now suppose that you build the cat pack as a hollow spool....
The Catpack material is rectangular (no waste) and is wound
around the spool...
The as the H2O2 goes from liquid at the center to Gas at the
outside the area of the cat pack increases
So one would expect a lower pressure drop. One can increase
the length of the tubular section without increasing
