摘要：

The effects of CoxMgyAl2Oz mixed oxides composition and ruthenium addition on the oxidation of propylene and carbon black (CB) were investigated. Different reactive cobalt and ruthenium oxide species were formed following calcination at 600 degrees C. The addition of ruthenium was beneficial for the CB oxidation under "loose contact" conditions and for propylene oxidation when the cobalt content was intermediate to low. The calculated activation energy for CB oxidation was decreased from 151 kj mol(-1) for the uncatalyzed reaction to 111 kj mol(-1) over the best catalyst. (C) 2012 Academie des sciences.
