Abstract: PCT No. PCT/EP94/00081 Sec. 371 Date Mar. 24, 1995 Sec. 102(e) Date Mar. 24, 1995 PCT Filed Jan. 13, 1994 PCT Pub. No. WO94/16798 PCT Pub. Date Aug. 4, 1994A process for the catalytic decomposition of dinitrogen monoxide in a gas stream by contacting the gas stream at temperatures of 200 DEG -900 DEG C. and pressures of 0.1 to 20 bar with a catalyst free of noble metals, the catalyst being prepared by combining a spinel CuAl2O3 with another spinel-forming metal component selected from the group consisting of tin, lead, zinc, magnesium, calcium, strontium and barium or mixtures thereof in elemental form or as an oxide or salt, and calcining at temperatures of 300 DEG -1300 DEG C. and under pressures of 0.1-200 bar in order to at least partially liberate the copper from the spinel by replacement with the other metal component.
