“…The activity (e.g.,d ehydration ability) of partially reduced MoO 3 depends on the extent of the reduction treatment;t he reduction temperature has been reported to affect the physical and catalytic properties of partially reduced MoO 3 severely. [20,43,44] To further examine the extento ft his effect, an onreduced catalyst and catalysts reduced at 350 and 500 8Cwere tested under the typicalreaction conditions (Figure 7).…”

The one‐step reaction of glycerol with hydrogen to form propene selectively is a particularly challenging catalytic pathway that has not yet been explored thoroughly. Molybdena‐based catalysts are active and selective to C−O bond scission; propene is the only product in the gas phase under the standard reaction conditions, and further hydrogenation to propane is impeded. Within this context, this work focuses on the exploration of the reaction pathways and the investigation of various parameters that affect the catalytic performance, such as the role of hydrogen on the product distribution and the effect of the catalyst pretreatment step. Under a hydrogen atmosphere, propene is produced primarily via 2‐propenol, whereas under an inert atmosphere propanal and glycerol dissociation products are formed mainly. The reaction most likely proceeds through a reverse Mars–van Krevelen mechanism as partially reduced Mo species drive the reaction to the formation of the desired product.

“…All rights reserved. thermodynamics enabled one to positively determine both the reaction mechanism and the rate-determining step (RDS) [1]. The concentration of butenes, potential reaction intermediates in a bifunctional mechanism, could be accurately measured, despite being present at levels more than three orders of magnitude lower than that of butane.…”

SSCI-VIDE+ING+FRMInternational audienceThe combination of kinetic and thermodynamic analyses can provide an in-depth knowledge of the crucial steps of catalyzed reactions. Earlier examples are recalled to stress how a reaction mechanism can be supported or rejected based on trivial reactant and product concentration analyses. The method is then applied to the important reaction of alcohol condensation, the so-called Guerbet reaction, which enables converting ethanol, a renewable feedstock, into higher alcohols. Important conclusions regarding the design of ethanol condensation processes can be drawn, as the main reaction mechanism occurring at high temperatures (ca. 350-420 degrees C) appears to be different from that proposed at low temperatures (< 250 degrees C). In the former case, the pathway involving acetaldehyde is negligible, and therefore a multi-step process based on ethanol dehydrogenation followed by acetaldehyde self-aldolization would be irrelevant.

“…determining step can be the isomerization of n-butene intermediate to iso-butene [26]. We showed in previous papers [13][14][15][16][17] that the heptane isomerization activities of H 2 -reduced MoO 3 and Pt/MoO 3 were closely related to their activities for propan-2-ol dehydration.…”
