Abstract

The paper presents the data on activity of the deposited catalyst based on vanadium. The developed catalyst allows conducting the process of oxidative conversion of propane into ethylene and hydrogen using CO₂ as an oxidant. The study of the activity of the developed vanadium catalyst at the oxidative conversion of propane showed that the maximum ethylene yield was 24.5% at: C₃H₈:CO₂=2:1, T=700°C and W=1000 h^-1. The increase of temperature to 800°C resulted in the in formation of 27.5% hydrogen. By methods of BET and XRD the developed catalyst 5% V/Al₂O₃, is differed by increase of specific surface area and bonding of the carrier with active phase, contributing to increase of efficiency of the developed catalyst in the oxidative conversion of propane to ethylene and hydrogen.
