Abstract: | A series of chromium-containing mesocellular silica foam (MCF) catalysts have been prepared and characterized in the oxidative
dehydrogenation (ODH) of propane between 350 and 600 °C. It is demonstrated that the chromium catalysts supported on MCF exhibit
much higher catalytic activity in terms of propane conversion and propylene yield than literature results obtained over chromium-supported
mesoporous SBA-15 or MCM-41 catalysts during the ODH of propane. Enhanced catalytic performance of the chromium-containing
mesoporous MCF catalysts has been attributed to the unique three-dimensional (3D), continuous, ultralarge mesopore structure
of the MCF materials, which allow a much faster internal molecular transport during the ODH of propane. |
