Application of the thermodynamic method to developing the process of producing methanol and dimethyl ether from synthesis gas

Experimental and theoretical study of the intrinsic kinetics for dimethyl ether synthesis from CO2 over Cu–Fe–Zr/HZSM‐5

“…In this case, the thermodynamic equilibrium of the methanol synthesis process is broken, 6,7 allowing for a higher conversion rate per pass; 8 additionally, the combination of both steps into one improves the driving force of the reaction 7,9 and from an economic perspective, lowers the cost of equipment for large-scale synthesis. 10 For all of these reasons, the one-step process is the primary focus of developmental research into DME synthesis from CO 2 .…”

Performance of CuO–ZnO–ZrO2 and CuO–ZnO–MnO as metallic functions and SAPO-18 as acid function of the catalyst for the synthesis of DME co-feeding CO2

“…The thermodynamic advantage of the single-step synthesis of DME over the conventional process (which includes the stages of methanol synthesis and its subsequent dehydration to DME) [9,10] facilitates the conversion of CO 2 when it is co-fed with syngas. Consequently, the process is considered strategic for the large-scale valorization of CO 2 [11,12].…”

A comparative thermodynamic study on the CO2 conversion in the synthesis of methanol and of DME

“…However, nowadays, the single-step process has gained much attraction for the synthesis of DME, using a bifunctional catalyst (with a metallic function for methanol synthesis and an acid function for its subsequent dehydration to DME) [23][24][25]. In this process, the synthesis of methanol and its subsequent dehydration take place in the same reactor, therefore, a sole reactor is required, and apart from the cost savings, the thermodynamic limitations are lower than those of the two-step reaction, due to the rapid in situ dehydration of methanol, which allows working in the single-step synthesis of DME at higher reaction temperature and lower pressure than in the methanol synthesis [26,27]. Moreover, improvements in the synthesis of DME are being studied, using membrane reactors (selective for removing H2O from the reaction medium), in order to shift the thermodynamic equilibrium of methanol dehydration [28,29].…”
