Conversion of Stearic Acid into Bio-Gasoline over Pd/ZSM-5 Catalysts with Enhanced Accessibility

Applied Sciences, 2019
Palladium supported on nanocrystalline ZSM-5 (n-ZSM-5, Si/Al = 32) and hierarchical ZSM-5 (h-ZSM-5) with different acidity (Si/Al = 33, 51, 122) were tested in the liquid-phase conversion of stearic acid under nitrogen atmosphere (6 bar).

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

Carbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Unbiased Reaction Network Exploration of C–C Coupling in Methane Dehydroaromatization Over Mo‐ZSM‐5

Chemistry – A European Journal, EarlyView.
Automated reaction route mapping reveals distinct methane coupling pathways over mono‐ and dinuclear Mo carbide species in ZSM‐5. Mononuclear [MoC]2+ selectively forms desorbable C2H4, whereas dinuclear [Mo2C2]2+ promotes strongly adsorbed C3/C4 intermediates linked to coke formation.
