Abstract
Recently, processes for obtaining various organic compounds from ethanol, which is derived from the processing of plant raw materials, have become highly relevant. Acetone is a valuable monomer that can be obtained from ethanol. It has been previously demonstrated that catalysts based on zinc oxides exhibit high activity in the conversion of ethanol to acetone. A review of the literature has shown that catalysts based on iron oxides also demonstrate high activity in this reaction. Therefore, the aim of this work was to study the vapor-phase conversion of ethanol to acetone on various binary zinc-iron oxide catalysts. This article describes a process for studying the paraphase conversion of ethanol to acetone on zinc-iron oxide catalysts Zinc-iron oxide catalysts of various compositions have been synthesized. The activity of the obtained catalysts was studied in the reaction of ethanol conversion. It was shown that samples rich in zinc oxide exhibit the greatest activity in the studied reaction. It has been established that the yield of acetone on the best catalysts reaches its maximum yield. The zinc-iron oxide catalyst of composition 9:1 showed the highest activity. catalyst, the maximum yield of acetone reaches up to 80%. Keywords: catalyst, ethanol, acetone, zinc, iron, vapor-phase conversion, iron oxides, temperature, reaction rate.
