METHOD FOR THE HIGH-TEMPERATURE CATALYTIC DECOMPOSITION OF N2O INTO N2 AND O2 |
摘要 |
Method of decomposing nitrous oxide (N2O) into nitrogen and oxygen at a temperature between 700 and 1000 degreesC and at high VVH (volumetric time speeds) in the presence of a catalyst containing a mixed oxide of zirconium and cerium in the form of a solid solution The catalyst has an effective specific surface greater than 25 m2/g, preferably between 60 and 150 m2/g, and the process takes place at a VVH between 30000 and 80000 h-1. The ratio by mass of ZrO2/CeO2 in the catalyst is between 80/20 and 20/80, preferably between 70/30 and 30/70. The catalyst also contains yttrium. |
