Dehydrierung von 1-Buten zu 1,3-Butadien in Gegenwart von Kohlendioxid

Universität Rostock, 2021

Abstract: Different vanadium oxide catalysts (VOx/SBA-15) were prepared, characterized and tested in the dehydrogenation of 1-butene to butadiene in the presence of CO2. Finely distributed, high VOx loadings are associated with high butadiene production and strong coke formation. Butadiene production on VOx/SBA-15 was higher in CO2 than in inert gas. Furthermore, three iron catalysts were investigated. In CO2, butadiene production on two of the catalysts tested was lower than in inert gas. The adsorption of water molecules on the catalyst surface could be one reason for this observation.
