The effect of the nature of the template on the acid properties and the activity of Zn-aluminosilicates in the course of conversion of the propane into aromatic hydrocarbons is studied. Using the method of by IR spectroscopy using adsorbed probe molecules (CO), data are obtained on the acidic characteristics of zinc aluminum silicates. It is established that the catalysts differ from each other by the distribution and ratio of acidic centers of different types. It is found out that a zinc aluminum silicate manufactured using ammonium bicarbonate as a template exhibits the highest aromatization activity in the course of propane conversion.
