Reversible Decarbonylation of a Metal Phosphaketene

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of a metalated phosphastannene through the base‐induced decarbonylation of a metal phosphaethynolate complex is described. This decarbonylation reaction appears to be reversible, allowing for the transfer of the phosphaethynolate moiety to other metal centers through salt‐metathesis reactions with concomitant release of a stannylene ...

Hydrogen from Biogas: Dynamic Modeling of an Integrated Shift Reactor

open access: yesChemie Ingenieur Technik, EarlyView.
A dynamic, two‐dimensional shift reactor model for the production of hydrogen from biogas is presented. This shift reactor enables the preheating of the biogas feed and, in parallel, reduces fixed‐bed temperatures, resulting in increased hydrogen yields. The model is validated with measurement data from a pilot biogas steam reforming plant.

Ecologic and Economic Evaluation of Combined Methanol Synthesis from CO2 and Biotechnological Upgrading to Value Products. Part 1: Environmental Impact

open access: yesChemie Ingenieur Technik, EarlyView.
The combination of methanol synthesis and biotechnological upgrading to value‐added products still faces some challenges in order to achieve a positive environmental impact and thus the goal of synergetic development of biotechnological and chemical processes.

Electrically Heated Multilayer Ceramic Composite Tubes for High‐Temperature Endothermic Reactions

open access: yesChemie Ingenieur Technik, EarlyView.
Innovative electrically heated multilayer ceramic stubes made of oxide ceramic matrix composite in a high‐temperature reactor were investigated. The multilayer design enables operation beyond 1000 °C in reactive atmospheres. Methane dry reforming achieved up to 80 % conversion but faced challenges such as soot formation at the heating element and ...

A catalytic sites contiguity study on atomically‐dispersed ZnO‐Cu/SiO2 catalysts to improve methanol formation from CO2 hydrogenation

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The synergistic interaction between Cu0/Cu+ and atomically dispersed ZnO (ADZn) sites enhances methanol production. The contiguity of these sites influences the methanol synthesis from CO2 hydrogenation. Abstract Cu‐ZnO‐based catalysts are commonly used in research on catalytic carbon dioxide (CO2) hydrogenation for methanol (MeOH) synthesis. This work
