Abstract
In the oxide gas absorbing arrangement disclosed in the specification, metal foils having a thickness ≦0.05 mm are coated with an oxide gas absorbing layer containing gamma aluminum oxide. One metal foil is corrugated and joined to a smooth foil and the combined foils are rolled into a cylinder to provide parallel gas passages in which exhaust gases are exposed to the oxide gas absorbing layer. To enhance absorption turbulence is created in the gas passages by twisting the cylinder to narrow and contort the individual passages.
