Hydrothermally-treated Na-X as efficient adsorbents for butadiene removal

Lioubov Kiwi, Jeremy Luterbacher, Florent Emmanuel Héroguel, Guillaume Bastien Baur

An efficient adsorbent for butadiene was synthesized via soft hydrothermal treatment (2 h in boiling water followed by 1 h calcination at 573 K) of industrial Na-X. The adsorption capacity of the zeolite was studied in the low concentration range (20–300 p ...

Increasing the activity of the Cu/CuAl2O4/Al2O3 catalyst for the RWGS through preserving the Cu2+ ions

Jeremy Luterbacher, Oliver Kröcher, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Yuan-Peng Du, Benjamin Pierre Le Monnier

Cu-Al spinet oxide is a highly active catalyst for CO2 conversion to CO. However, it suffers from low surface area. By depositing a silica layer, we protected the catalyst surface and preserved the Cu2+ ions during the calcination process. These ions form ...

Selectivity control during the single-step conversion of aliphatic carboxylic acids to linear olefins

Jeremy Luterbacher, Florent Emmanuel Héroguel, Jher Hau Yeap, Bartosz Rozmyslowicz

We have studied the single-step catalytic conversion of biomass-derived aliphatic carboxylic acids to linear olefins via tandem hydrogenation/dehydration reactions. Hexanoic acid was converted to a mixture of hexenes (92.0% selectivity) over silica–alumina ...

Prominent role of mesopore surface area and external acid sites for the synthesis of polyoxymethylene dimethyl ethers (OME) on a hierarchical H-ZSM-5 zeolite

Jeremy Luterbacher, Oliver Kröcher, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Christophe Jean Baranowski

H-ZSM-5 zeolite has been shown to be an active catalyst for the synthesis of polyoxymethylene dimethyl ethers (OME). However, we demonstrated – by passivation of the zeolite's external surface – that the reaction rate is limited due to severe internal diff ...

Insights into the Nature of the Active Sites of Tin‐Montmorillonite for the Synthesis of Polyoxymethylene Dimethyl Ethers (OME)

Jeremy Luterbacher, Oliver Kröcher, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Christophe Jean Baranowski

In this study,we reportthat intercalationof tin into montmor-illoniteclay (Sn-MMT)boostscatalyticactivityfor the synthesisof polyoxymethylenedimethylethers,a promisingdieselfueladditive.This increasein activityis attributedto the formationof a hierarchical ...
