The energy crisis of the century is a motivation to present processes with higher energy efficiency for production of clean and renewable resources of energy. Hence, a catalytic heat exchanger reactor for production of dimethyl ether (DME) from syngas, and hydrogen and methyl formate (MF) from methanol is investigated in the present study. The proposed configuration is equipped with two different membranes for in-situ separation of products. Syngas is converted to DME through an exothermic reaction and it supplies a part of required energy for the methanol dehydrogenation reaction. Produced water in the exothermic side and produced hydrogen in the endothermic side are separated by using appropriate perm-selective membranes. In-situ separation of products makes the equilibrium reactions proceed toward higher conversion of reactants. A mathematical model based on reasonable assumptions is developed to evaluate molar and thermal behavior of the configuration. Performance of the system is aimed to enhance by obtaining optimum operating conditions. In this regard, Genetic Algorithm is applied. Performance of the heat exchanger double membrane reactor working under optimum conditions (OTMHR) is compared with a heat exchanger reactor without membrane (THR). OTMHR promotes methanol conversion to MF to %87.2, carbon monoxide conversion to %95.8 and hydrogen conversion to %64.6.

“…Moreover, the high-temperature co-electrolysis of steam and carbon dioxide enables to convert electricity into a syngas composed of carbon monoxide and hydrogen [2,4]. This gas mixture can be transformed in a second step in liquid or gaseous hydrocarbons with conventional catalytic processes working at high pressure between 10 and 100 bar [5]. In this case, an integrated system working directly under pressure could also be beneficial in terms of efficiency and cost [3,6].…”

Mixed ionic electronic conductors (MIECs) oxides are used as electrode materials for solid oxide cell (SOC) application, as they combine high electronic conductivity as well as high oxygen diffusivity and oxygen surface exchange coefficients. The ionic transport properties can be directly determined thanks to the isotopic exchange depth profiling (IEDP) method. To date, the reported measurements have been performed at ambient pressure and below. However, for a higher efficiency of hydrogen production at the system level, it is envisaged to operate the cell between 10 and 60 bar. To characterize the MIEC oxides properties in such conditions, an innovative setup able to operate up to a total pressure of 50 bar and 900°C has been developed. The main goal of this study was to compare the behavior of two types of reference materials: the oxygen deficient La‐Sr‐Fe‐Co perovskites, and the overstoichiometric lanthanide nickelates Ln2NiO4+δ (Ln = La, Pr, Nd). Diffusion and surface exchange coefficients obtained under 6.3 bar of oxygen are measured and their evolution discussed in light of the change in oxygen stoichiometries. This analysis allows better understanding of the dependency of the surface exchange coefficient with the oxygen partial pressure.

Although carbon dioxide is important as an abundant carbonaceous raw material, so far, its utilization in chemical processes has been rather limited. This review covers the reactions of CO, employed in industry, such as the production of urea, the Kolbe-Schmitt reaction, the synthesis of cyclic organic carbonates and the use of COz in methanol synthesis. Interesting recent developments in COZ chemistry, such as the reactions catalyzed by transition metals, are also described. Apart from the synthesis of polymers and hydrocarbons, the production of oxygen-containing substances appears to be very profitable and attractive for future industrial applications. Not only can derivatives of formic and carbonic acids be produced but also longer-chain carboxylic acids and their derivatives by reactions of carbon dioxide with hydrocarbons such as alkynes, alkenes and I ,3-dienes.
