Abstract
The catalytic activity of copper oxide in the carbon black reaction with air oxygen has been studied with the catalyst addition to a sample by different methods. It has been shown that copper oxide added as copper acetate from the ether solution accelerates the carbon black oxidation at 700 K approximately by a factor of 110, copper acetate added from a water solution accelerates the carbon black oxidation by a factor of 300, and if the catalyst is added as a copper-polymer carboxylated complex, the carbon black oxidation is accelerated by a factor of 460. It has been assumed that the difference in catalytic activity of copper oxide added by various methods is caused by the nonuniformity of the copper distribution over the carbon black surface.
