“…It was reported that in few studies, the calcination temperature had shown significant impact on the crystallite sizes of the active metal as well as its dispersion and therefore it positively affected on the catalyst activity and stability [12], [18]. Moreover, it has been noted that the activity of the catalyst depends on particle size of the nickel oxide [15]. Summing up from this, it can be considered that the distribution of metals in our synthesized catalyst were increased when the calcination temperature and time were increased.…”

In this work, the influence of catalyst preparation temperature on its structure was investigated. We have synthesized 12 different Ni/ZrO2 catalysts by varying the calcination temperature, time, and active metal content, and these catalysts will be further used in the carbon dioxide methanation reaction. Structure and properties of the catalysts were determined using XRD and SEM analysis. Therefore, Ni content of the catalysts were measured by ICP-OES.Regarding to the crystal size calculation using XRD data by Scherer equation, when calcination time was increased the average crystal size of nickel oxide was decreased from 42.38 nm to 38.93 nm whereas it decreased to 39.23 nm when the calcination temperature was increased. This shows that the distribution of active metals in the catalyst increases when the heat treatment parameters are increased. In addition, it can be assumed that the activity of the catalyst can be enhanced when the calcination temperature and time were increases.

The effect of the amount of Mn (II) in the precursor of manganese-aluminium oxide catalysts for the complete oxidation of hydrocarbons on the phase composition and kinetic parameters of the reaction was studied. It was shown that an increase in the amount of manganese in the catalysts results in an increase in the constants of C1-C3 hydrocarbons oxidation reaction rates. An increase in the number of carbon atoms in the alkane leads to an increase in the reaction rate and a decrease in the energy of reaction activation. Promising catalysts for the catalytic combustion of hydrocarbons were identified.
