OK well,

at about 50 to 250 ppm for Fe3o2 works a a fuel catalyst.

It's cheap enough.. bit of steel wool in a bucket of corn starch and mix

it through holds pellets and sawdust together.

25 Grams per 100 Kgs.

thats about 1 steel wood pad per 100 KG of wood.

it can be kept in catalyst form buy a magnet or coil.

currie temp is 580 C or so .. so it's just about perfect for

cracking those tough bits.

I have not tried this yet .. they use it in the FT process

to enhance the Water gas shift.

Catalysis is a great way to go...It can make unsolvable problems solvable. Dolomite and lime aren't exactly expensive, either.
For catalyst cleaning, rather than using a blowtorch, why not hit it using a burner fueled with stored syngas and triggered by the GCU?
