Abstract
The conversion of ethane to ethylene is an important reaction for industrial use, as ethylene serves as a building block for more complex organic molecules. Current methods of ethylene production are very energy intensive, and do not produce high yields from their starting materials. The purpose of this project is to investigate catalysts for the oxidative dehydrogenation of ethane. Perovskite materials of varying composition—Niobium-doped strontium titanates and niobium/chlorine-codoped strontium titanates—were synthesized by a sol-gel method. The activity of each catalyst was tested in a packed-bed reactor, with results analyzed by gas chromatography. The most active catalysts will undergo further electrocatalytic testing in order to determine their electrical properties. Catalysts with good activity, selectivity, and conductivity could be used industrially in order to replace energy-intensive steam cracking methods for ethylene production with more efficient oxidative dehydrogenation.
