摘要：
The oxidation of resinous substances on a Cu-Zn-Cr-Al catalyst and on model systems ZnO, Cr2O3, Al2O3, CUO, CU0, CUO-ZnO, CuO-Cr2O3 was studied in conjunction with methods of x-ray photoelectron spectroscopy and x-ray phase analysis. The rate of oxidation of resinous substances was found to depend on the valence state of copper in the catalyst. It is suggested that CO2 is formed through an intermediate complex of a fragment of the resinous substances and copper(I) oxide.
