Heterogeneous-homogeneous reactions involving free radicals in processes of total catalytic oxidation

Using a modified matrix isolation ESR technique conditions for initiation of a heterogeneous-homogeneous reaction by total oxidation catalysts CuCr 2O 4/γ-Al 2O 3 and 0.64% Pt/γ-Al 2O 3 and reaction dependences at atmospheric pressure have been studied. The dependences of homogeneous component contr...

Zusammenfassung:	Using a modified matrix isolation ESR technique conditions for initiation of a heterogeneous-homogeneous reaction by total oxidation catalysts CuCr 2O 4/γ-Al 2O 3 and 0.64% Pt/γ-Al 2O 3 and reaction dependences at atmospheric pressure have been studied. The dependences of homogeneous component contribution into the total conversion on the concentration and the ratio of reactants and catalyst temperature have been established.
