Study of some spectral properties of nanocatalysts prepared for the mixed oxide system MoO3/Co2O3 and calcined at 600oC

In this research, a mixed oxide catalysts of MoO3/Co2O3 was prepared using the method. The samples were calcined at a temperature of 600oC. Several techniques were used to characterize the prepared catalysts, including SEM, XRD, Raman spectroscopy. The SEM images of molybdenum oxide revealed that the particles have a rod-like morphology, whereas the particles in cobalt oxide images appeared to be nearly spherical in shape. A morphological integration between the two prepared oxide was observed in the mixed oxide samples, and all catalysts exhibited nanoscale dimensions. XRD analysis indicated that both molybdenum oxide and the mixed oxide samples exhibit an orthorhombic crystalline structure with nanoscale dimensions and the values of d range between 1.304 nm and 7.392nm. The Raman spectra revealed the presence of characteristic peaks attributed to molybdenum oxide in all the prepared catalysts, as well as the emergence of a new peak associated with the formation of the mixed CoMoO4 phase in the mixed oxide samples containing > 1 wt.% Co2O3.

The catalytic activity of ethanol gasification in a continuous flow system using locally prepared Mo-O-Co co-oxide system catalysts calcined at 450°C

In this research, the catalytic activity of the gas-phase conversion of ethanol was studied using a continuous flow system and locally prepared catalysts based on the mixed oxide system Mo-O-Co containing (0-25 wt.% Co2O3), with the aim of producing acetaldehyde and ethylene. The reaction was studied at temperatures ranging from 150oC to 300oC, and it has found that the overall conversion rate gradually increased with temperature. It has found that the conversion reaction using molybdenum oxide and the mixed oxide sample proceeds through both dehydrogenation and dehydration reactions, with dehydrogenation being the predominant reaction. An increase in catalytic activity and a shift in the reaction toward dehydrogenation were observed after the addition of cobalt oxide. The highest overall conversion rate of the reaction reached 97% using catalysts containing 15, 25 wt.% Co2O3, while the highest conversion rate to acetaldehyde was 96% with cobalt oxide, and the highest conversion rate to ethylene was 44.5% with a selectivity 45.88% using the catalyst containing 25wt.% Co2O3. The stability of the catalyst containing 15wt% Co2O3 was tested in the ethanol conversion at 250oC for a continuous period of fifty hours. It was observed that the catalysts performance remained stable with no decrease in conversion or reaction selectivity.

The Catalytic Activity of Ethanol Vapor- phase conversion in a Continuous Flow System Using Locally Prepared Mixed Oxide Catalysts Mo-O-Co and Calcined at 450oC

Pure MoO3 and Cr2O3 and samples of the mixed oxide system Mo-O-Cr (1-15 wt.% Cr2O3) were prepared by mechanical mixing method, then calcined at 500 oC. The textural properties for the catalysts were investigated by analysis of N2 adsorption data at 77K. The results showed that the adsorption isotherms of N2 at 77K for all catalysts are mixed of types I and II. The specific surface areas were calculated by BET , V-t and V-αS methods. The analysis of the adsorption data proved that SBET , St and Sα are in good agreement . It has found that the specific surface area increased with adding Cr2O3 to MoO3. The specific surface area was gave maximum value for the catalysts containing 5wt.% and 10 wt.% Cr2O3. The pore diameter showed that the catalysts contain mesopores and micropores but its mainly mesoporous. The total pore areas volume VT increased with adding Cr2O3 and showed maxima for the catalysts containing 5wt.% and 10 wt.% Cr2O3.
