“…The procedure was the same as in our previous work. 25 The experiments were performed with around 15 g of dried zeolite 3A and approximately 50 g of the liquid solution. The density of the zeolite 3A was also adopted from our previous work.…”

“…22−24 In a prior work, we undertook measurements and modeling of the equilibrium adsorption in the system (formaldehyde + methanol + water) on zeolite 3A. 25 The study demonstrated the preferential adsorption of water over formaldehyde and methanol, highlighting the potential of 3A zeolite 3A for efficient water separation in water-tolerant OME 3−5 production processes. Nonetheless, we also discovered that the coadsorption of formaldehyde and methanol can be substantial under certain conditions.…”

The separation of water from mixtures containing formaldehyde, methanol, water, and poly(oxymethylene) dimethyl ethers (OME) is a fundamental step in the water-tolerant OME 3−5 production processes. Several approaches have been discussed in the literature, including pervaporation, reactive distillation, and adsorption. This study focuses on the adsorption on zeolite 3A. Building on prior research, we extend an existing equilibrium adsorption model for systems containing formaldehyde + methanol + water to systems containing OME. Experimental data on breakthrough curves of formaldehyde, methanol, and water from a laboratory-scale column are presented. A comprehensive column model, encompassing chemical and adsorption equilibria, adsorption kinetics, and fluid dynamics, accurately predicts the breakthrough curves. The regeneration of the zeolite 3A is shown experimentally. A stream table for a water-tolerant OME 3−5 production process including adsorption is given, showing that water can be separated from mixtures containing formaldehyde, methanol, and OME with a high selectivity.

“…16,33 Furthermore, the product purification is more complex due to several azeotropes, complex vapor-liquid-liquid equilibria (VLLE), challenges regarding FA solidification and the separation of H 2 O from the process. [34][35][36][37] On the other hand, anhydrous reaction systems lead to a much simpler product purification. However, in this case H 2 O needs to be separated from the feedstock before entering the OME reactor, which is especially energy intense for the production of reactant TRI.…”

“…H 2 O management remains a key hurdle for the realization of a scalable OME 3-5 production. Research and development focused in the last decades on various H 2 O separation strategies, such as extraction [78][79][80][81][82][83][84][85], adsorption [76,86], or membranes [87]. The long-term stability of the materials applied for the previous concepts, as well as the efficiency and the scalability of these approaches are crucial for their application and remain under investigation.…”

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.
