Abstract
A microlith catalyst bed for use in automotive catalytic converters or gas turbine catalytic combustors. The microlith catalyst bed of the present invention advantageously utilizes a wire cloth (10) woven to form a spiral wound flat helix (or coil). Woof wires (14) are woven into warp wires (12) in a polar weave pattern. There is no leftover scrap when forming the microlith catalyst bed. 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.
