Abstract

The properties of hopcalite in alumina matrix have been investigated and compared with conventional hopcalite catalyst. It was found using X-ray diffraction, DTA-TG, TEM, and activity measurements in oxidation of n-butane that the presence of alumina matrix leads to weakening of phase changes of hopcalite and recrystallization of CuMn2O4 spinel. The modified catalyst was also found to show higher activity after calcination at 1073 K than pure hopcalite under the same conditions.
