    Opis:
    The following contribution presents the results of studies on the effects of alkali metals on the physicochemical properties and the effectiveness of a Co-Mo/Al$\text{}_{2}$O$\text{}_{3}$ catalyst for the water gas shift reaction. It has been shown that the addition of alkali metals modifies the properties of Co-Mo catalysts, resulting in a significant increase in activity of catalysts in water gas shift reaction. The greatest effect was observed in the case of sodium-promoted reaction.

    Opis:
    The results of activity studies of four catalysts in methanol synthesis have been presented. A standard industrial catalyst TMC-3/1 was compared with two methanol catalysts promoted by the addition of magnesium and one promoted by zirconium. The kinetic analysis of the experimental results shows that the Cu/Zn/Al/Mg/1 catalyst was the least active. Although TMC-3/1 and Cu/Zn/Al/Mg/2 catalysts were characterised by a higher activity, the most active catalyst system was Cu/Zn/Al/Zr. The activity calculated for zirconium doped catalyst under operating conditions was approximately 30% higher that of TMC-3/1catalyst. The experimental data were used to identify the rate equations of two types – one purely empirical power rate equation and the other one - the Vanden Bussche & Froment kinetic model of methanol synthesis. The Cu/ZnO/Al2O3catalyst modified with zirconium has the highest application potential in methanol synthesis.

    Opis:
    Technological problems of natural gas desulfurization in syngases manufacturing plants have been discussed and the results of investigations on the activity of the model Ni-Mo/Al$\text{}_{2}$O$\text{}_{3}$ catalyst in hydrogenation of selected sulfur compounds have been presented. The HDS reaction rate is dependent on a compound structure. The hydrogenation rate on the Ni-Mo/Al$\text{}_{2}$O$\text{}_{3}$ catalyst for the given sulfur compound increases in the order: CS$\text{}_{2}$(CH$\text{}_{3}$)$\text{}_{2}$S>C$\text{}_{4}$H$\text{}_{10}$S>C$\text{}_{2}$H$\text{}_{6}$S$\text{}_{2}$C$\text{}_{4}$H$\text{}_{4}$S.

    Opis:
    Sweet pepper belongs to vegetables with high biological value, characteristic taste and health-promoting features, which depend on the content of many elements with antioxidant capacity. Pepper fruits are an important source of mineral components for people. The aim of this study was to determine the effect of different foliar feeding regimes with the use of calcium on the content of macro- and microelements in sweet pepper fruits. The experiment with the sweet pepper cultivar Caryca F1 was carried out under field conditions in 2010-2011. Various calcium preparations: Ca(NO3)2 , Insol Ca, Librel Ca, were applied in plant nutrition. The evaluated preparations were sprayed 3 and 5 times, in the concentration of 1%, until complete wetness of the plants. Control fields were sprayed with water. No significant influence of the examined factors on the dry matter content (%) was recorded in the fruits of cv. Caryca F1 sweet pepper cultivated in a field. However, the influence of the applied calcium preparations on the content of N-total, P, Ca, Fe, Zn, Cu in pepper fruits was shown to vary. After an application of Ca(NO3)2, higher concentrations of K, Zn, Cu were demonstrated; an application of Insol Ca stimulated a higher content of K and Cu; more K, Fe, Zn and Cu occurred in the fruit after feeding with Librel Ca, and the content of P was lower after an application of Insol Ca and Librel Ca, all versus the control. The different number of treatments did not have any significant effect on the chemical content of pepper fruits, except for Fe and Mn, where 5 treatments increased the content of these elements in pepper fruits. The positive influence of the applied calcium preparations and of the number of treatments on the accumulation of Ca in pepper fruits were proven. For example, 5 treatments were demonstrated to have increased the calcium content in fruits by an average 25.3%, and 3 treatments raised the above trait by 15.3% above the control.
