Heterogeneously catalyzed synthesis of oxymethylene dimethyl ethers (OME) from dimethyl ether and trioxane

Optimization of the direct synthesis of dimethyl ether from CO2 rich synthesis gas: closing the loop between experimental investigations and model-based reactor design

“…2.2.2 Thermodynamic considerations. The equilibrium constants K f, j of each reaction j were computed based on the stoichiometry of the involved reactions with the commercial software Aspen Plus® using the built-in reactor model REquil in the relevant temperature range of 200-300°C at 50 bar, and fitted to the simplified function given in eqn (6). The parameters A j and B j are reported in Table 2.…”

“…Dimethyl ether (DME) serves as an example system in our work since it is subject of current research due to its manifold possible applications in a world of changing fuel feedstocks, especially in the vehicle technology as a diesel alternative, as well as in the chemical industry as feedstock for the manufacturing of short-chain olefins. [4][5][6] Dimethyl ether is one of the so called multi-source fuels since it can be produced from different raw materials such as petroleum, natural gas, coal and also from renewable resources such as biomass. 7 DME can be produced directly from syngas over a dual catalyst system in one reactor.…”

A Computational Investigation of OME‐synthesis through Homogeneous Acid Catalysis

“…Experimentally, OME synthesis is carried out in solution typically using ambient to elevated temperatures and often pure reactants as solvent ,,,. We will study the reaction of OME1 and TOX without additional solvents at room temperature.…”

Processes for the production of OME fuels

“…has not been observed so far without strong side-product formation (even in laboratory environment) [17]. This is the reason why OME1 is an important intermediate when longer-chain OME are produced.…”
