THE CATALYTIC DECOMPOSITION OF DINITROGEN MONOXIDE WHICH IS PURE OR PRESENT IN GAS MIXTURES

摘要

A process is disclosed for catalytically decomposing nitrous oxide pure or contained in gaseous mixtures at 200 to 900 .degree.C by using a catalyst prepared by combining CuAlzO4 with tin, lead, an element of the main or secondary group II of the periodic table of elements as an oxide or a salt or in the elementary form, and calcination at 300 to 1300 .degree.C and at a pressure from 0.1 to 200 bars.
