Ethane pyrolysis on Al2O3, ZrO2, SiO2 oxides supported on fechral under conditions of resistive heating

Abstract

The conversion of ethane on Al2O3, ZrO2, SiO2 oxides supported on fechral carrier under conditions of its resistive heating was investigated. A cold gas mixture consisting of ethane and nitrogen was fed to a spiral heated by an electric current to 900-1100 °C. It was shown that the ethane pyrolysis proceeds with the predominant formation of ethylene in the range of 650–950 °C. At higher temperatures, the yield of methane and carbon by-products increases significantly. The selectivity and yield of ethylene are affected by the nature of the carbon deposited.
