ABSTRACT:
A conical microlith catalyst reaction system for use in automotive catalytic converters or gas turbine catalytic combustors advantageously utilizes a microlith catalyst bed formed from a wire cloth (10) woven into a spiral wound flat helix (or coil). The spiral windings of the wire cloth helix are wound to form a uniform angle less than 90.degree. relative to a ceramic housing formed from an inner ceramic hub (102) and an outer ceramic shroud (104). Warp wires (12) further carry electrical current via bus bars (106, 108) for electrically heating the catalyst bed. Lightoff time for the bed is significantly reduced due to the heating. The angled spiral windings create the conical shape to prevent buckling of the spiral windings due to thermal stress caused by the microlith catalyst bed becoming hot.
