Research Topic

Investigation of the direct catalytic conversion of methanol and ethanol to propylene

The aim of the project are fundamental mechanistic investigations of direct and highly selective conversion routes of methanol (C1) and ethanol (C2) to propylene (C3). By variation of catalyst material and reaction conditions, the mechanistic background and kinetics of the direct reaction route vs. complex hydrocarbon pool reactions to propylene are examined to conclude suitable process and reaction conditions for industrial application.
