“…From methanol and FA an OME 1 is produced to be reacted further with FA an for higher OME synthesis. Therefore, no H 2 O is formed within the OME synthesis in this route [90].…”

“…Therefore, instead of oxidizing this valuable H 2 to H 2 O following the state-of-the-art FA aq synthesis (Equation ( 6)), the reutilization of H 2 following the FA an synthesis (Equation ( 7)) lowers the amount of H 2 required to produce the target end product OME 3-5 . This reflects significantly on the operational costs, especially considering the context of PtX processes using green H 2 [90].…”

“…From methanol and FAan OME1 is produced to be reacted further with FAan for higher OME synthesis. Therefore, no H2O is formed within the OME synthesis in this route [90]. While the solid pFA presents a cheaper feedstock than TRI, it still contains about 1-10 wt.% H2O [89], which requires removal from the process.…”

“…The potential of the choice of the FA source-being either concentrated formalin or FA an -is compared with respect to the specific energy demand, the carbon footprint and the specific wastewater formation based on the results of Mantei et al [90]. Figure 6 compares the specific energy demand per ton OME 3-5 produced depending on the FA source, achieved after heat integration between all subprocesses.…”

“…OME production is based on MeOH, which can be produced from renewable feedstock such as green H 2 and CO 2 [54,90]. While a large-scale production of MeOH based on renewable feedstock has already been implemented [91], only a paucity of information remains available regarding OME production plants.…”

Sector coupling remains a crucial measure to achieve climate change mitigation targets. Hydrogen and Power-to-X (PtX) products are recognized as major levers to allow the boosting of renewable energy capacities and the consequent use of green electrons in different sectors. In this work, the challenges presented by the PtX processes are addressed and different process intensification (PI) strategies and their potential to overcome these challenges are reviewed for ammonia (NH3), dimethyl ether (DME) and oxymethylene dimethyl ethers (OME) as three exemplary, major PtX products. PI approaches in this context offer on the one hand the maximum utilization of valuable renewable feedstock and on the other hand simpler production processes. For the three discussed processes a compelling strategy for efficient and ultimately maintenance-free chemical synthesis is presented by integrating unit operations to overcome thermodynamic limitations, and in best cases eliminate the recycle loops. The proposed intensification processes offer a significant reduction of energy consumption and provide an interesting perspective for the future development of PtX technologies.

Non‐oxidative Dehydrogenation of Methanol to Formaldehyde over Bulk β‐Ga₂O₃

The non-oxidative dehydrogenation of methanol to formaldehyde is considered a dream reaction compared with the classical oxidative route, because the valuable coupled product hydrogen is formed instead of water, and the produced anhydrous formaldehyde is highly suitable for the further synthesis of oxygenated synthetic fuels. This study reports on the high catalytic performance of pure β-Ga 2 O 3 in this reaction at temperatures between 500 °C and 650 °C. At 550 °C and a GHSV of 45500 h À 1 , an initial selectivity to formaldehyde of 77 % was obtained at a methanol conversion of 72 %. Performing the reaction at temperatures beyond this range and lower GHSV resulted in a lower formaldehyde selectivity. The catalyst suffered from deactivation caused by formation of carbon deposits, but it was possible to regenerate its initial activity at 500 °C and 550 °C completely by an oxidative treatment. Irreversible deactivation occurred at 650 °C due to partial volatilization of Ga 2 O 3 .

Online NMR measurements are introduced in the current study as a new analytical setup for investigation of the oxymethylene dimethyl ether (OME) synthesis. For the validation of the setup, the newly established method is compared with state‐of‐the‐art gas chromatographic analysis. Afterwards, the influence of different parameters, such as temperature, catalyst concentration and catalyst type on the OME fuel formation based on trioxane and dimethoxymethane is investigated. As catalysts, AmberlystTM 15 (A15) and trifluoromethanesulfonic acid (TfOH) are utilized. A kinetic model is applied to describe the reaction in more detail. Based on these results, the activation energy (A15: 48.0 kJ mol−1 and TfOH: 72.3 kJ mol−1) and the order in catalyst (A15: 1.1 and TfOH: 1.3) are calculated and discussed.
