Abstract: The effect of Mg-Al mixed oxides in the composition of the catalysts on the distribution of the target cracking products of a mixture of vacuum gas oil with sunflower oil was studied. It was established that by changing the molar ratio of magnesium to aluminum in mixed oxides, it is possible to control the process of deoxygenation of oxygencontaining compounds. For catalyst samples containing mixed oxides with high values of the molar ratio to Mg:Al, the content of carbon dioxide increased, which indicates an increased activity of the decarboxylation reaction. However, there was a significant decrease in the conversion of mixed raw materials and the yield of the gasoline fraction in comparison with a sample that does not contained mixed oxide. The solution was to introduce additional metal into the mixed oxide. So for catalysts containing Co, Mg-Al or Zn, Mg-Al mixed oxides was shown, an increase in the conversion of mixed raw materials by 5.0 wt. % relative to the sample containing mixed oxide without additional metal, as well as increasing the yield of gasoline fraction by 1.6-3.0 wt. % It was found that the modification of mixed oxides with cobalt or zinc cations does not lead to a significant change in the distribution of inorganic products, which indicates that the catalyst remains active in the decarboxylation reaction.
