Реферат:
Oxidative conversion of the propane-butane mixture by air into oxygen-containing compositions was studied. It were determined the optimum reaction temperature, contact time, change in the space velocity in the process of partial oxidation of C3-C4 hydrocarbons. The physicochemical studies of the initial and treated catalysts were carried out under experimental conditions. When changing the content of the active component from 1 to 10% on the carrier, it was found that the most optimal is 1% MoCrGa/TC catalyst, on which up to 89.92% of hydrogen is obtained. As a result of varying the composition of the catalyst, the content of the active phase, the ratio of reactants, up to 70% of ethylene was obtained. In addition, in some cases, CH3OH was obtained, the maximum yield of which is 22%, and also up to 35% of methyl ethyl ketone. As a result of EM and XRD studies, it was shown that under reaction conditions, a new Cr2O5 phase is formed on the catalyst surface (corresponding to the Cr2+ and Cr3+ transition to Cr5+), as well as joint Mo phases with Cr in different valence states, the physical meaning and role of which are to be determined.
