Research topic

Investigation of the catalytic, direct conversion of methanol-ethanol mixtures to propene                                                                                                                                                 The aim of the scientific work is the direct conversion of methanol (C₁) and ethanol (C₂) to propene (C₃) on porous, zeolitic materials. By adapting the catalyst material, the reaction of the short-chain alcohols should be more selective at lower temperatures than in conventional, industrial processes. This makes an ecological route for propene production accessible.
