Аннотация

In the Republic of Kazakhstan, despite the huge reserves of hydrocarbon raw materials, it is mainly
consumed in the form of domestic, industrial and motor fuels, remains are burned as part of the exhaust gases, or
again driven into the oil-bearing strata. Propane, which is in the composition of associated gases and formed in
petrochemical, in the first case, either burned or used as fuel after separation. In the second case, it is partially used in
petrochemicals, as well as municipal or motor fuel, the rest is exported. In order to identify the ability of the
developed catalysts to regeneration or reoxidation and determine the energy characteristics of hydrogen and oxygen,
the study was carried out by the methods TPR and TPO, as well as by TEM, XRD and BET for determine the
morphology, particle size and their chemical composition. In the present work it is shown that on the developed
5%V/(ϴ+α)Al2O3 catalyst the process of oxidative conversion of propane passes with the formation of 24.5%
ethylene and 27.5% hydrogen under the optimal conditions: 66.5% C3H8 + 33.5% CO2, T = 700o
C, W = 1000 h-1 and
C3H8 : CO2 = 2 : 1.
