“…Functional derivatives of these compounds by reason of the high activity of a multiple bond are used in the synthesis of polymeric and composite materials for special purposes, physiologically active compounds, as well as the chiral synthons for the directed obtaining analogues of natural compounds and medicaments. The most widely studied reaction of catalytic dehydrogenation of naphthenes hydrocarbons in the oil field [1,2]. It is known that this thermodynamically limited reaction proceeds under hard conditions lead to aromatization and resinification of significant part of the hydrocarbon fraction, as well as rapid coking and deactivation of the catalysts.…”

The oxidative dehydrogenation of alicyclic diene hydrocarbons refers to scarcely studied heterogeneous catalytic reactions which proceed with the participation of oxygen. The dehydrogenation of methylcyclopentane is an endothermic reaction. To improve the reaction kinetics, this research was to develop a structured catalyst by conductive metals (Cu, Zn, Co, Cr) support which could hold an adherent catalytic layer. The active phase was impregnated onto these support metals and the developed catalyst was tested for the dehydrogenation of methylcyclopentane. The catalyst preparation involved three main key steps which were support oxidative reaction, loading of active particles on the catalyst surface, preparation of an active catalyst layer on the surface finally bringing the catalyst into the active phase. Different types of catalyst activation and deactivation mechanisms stability have been studied in this investigation. The advantage of this works, the oxidative dehydrogenation of methylcyclopentane is that it occurs at the expense of oxygen in the air. The zeolite structure study helped identify the effect of the combination of catalysts, and adsorption of metals on clinoptilolite and dispersion on the selectivity of the catalyst particles. Numerical values of the kinetic parameters were calculated

The activity of the Ni/diatomaceous earth catalyst used in the process of obtaining acetone from isopropyl alcohol was studied in a laboratory setup over a wide temperature range (150–3500C) at atmospheric pressure. The analysis of raw materials and reaction products was carried out by the chromatographic method. In the process of isopropyl alcohol conversion on the Ni/diatomaceous earth catalyst surface, the formation of compaction products and the effect of oxygen and hydrogen on the catalyst surface were studied using a Mag-Ben setup equipped with a quartz-spring reactor. The formation of compaction products on the surface of the Ni/diatomaceous earth catalyst was determined by thermogravimetric and kinetic methods. The maximum amount of compaction products is formed at a temperature of 3000C and above on the Lewis sites. Thermogravimetric studies showed that the formation of compaction product on the surface of the Ni/diatomaceous earth catalyst is time and temperature dependent.
