Assessing the techno-environmental performance of CO2 utilization via dry reforming of methane for the production of dimethyl ether

Consequential life cycle assessment of carbon capture and utilization technologies within the chemical industry

“…53 The chosen CO 2 -based technology is the direct production of DME via synthesis gas and methanol as intermediates. 11…”

“…[2][3][4] Existing life cycle assessments (LCA) of CCU investigate the environmental impacts of the production of a chemical, for example, C 1 basic chemicals like carbon monoxide, 5 syngas, 6,7 formic acid, 5,8,9 methane 6,7,[10][11][12][13][14][15][16] and methanol. 5,6,[12][13][14][17][18][19] Other LCAs focused on the assessment of more complex molecules produced via CCU, like methyl propionate, 20 DME, 11,19,21 DMC, 17,22 OME, 23 (jet) fuels, 24,25 and polymers. 4,14,21,26,27 A recurrent conclusion from these studies is that emissions of greenhouse gases are reduced when producing the chemicals via CCU while using electricity from renewable resources compared to fossil-based production.…”

Decision tree‐based modeling of CO2 equilibrium absorption in different aqueous solutions of absorbents

“…Along with upgrading the energy-related technologies to reduce the pollutant emissions, CO 2 capture process should be used for minimizing the environmental damage caused by the energy sector. The separated CO 2 may be employed for algae production [1][2][3] or it can be converted into some useful fuels and chemicals [4][5][6]. Furthermore, geo-sequestration of CO 2 [7][8][9], methane-CO 2 replacement in hydrate reservoirs [10,11], and CO 2 -enhanced oil recovery [12][13][14] are other approaches for handling the captured CO 2 .…”

Analysis of CO2 utilization into synthesis gas based on solar thermochemical CH4-reforming

“…Due to its abundance and availability in the world, solar energy is used to offset a part of the energy required for Gas-to-Liquid (GTL) processes to meet the growing demand for liquid fuels produced sustainably [10,15] . Solar-driven methane reforming process is one of the main routes for volumetric CO 2 utilization into H 2 , CO or syngas which is an important energy carrier, ultimately clean fuel and precursor materials of chemical industries [16][17][18][19] . High-temperature CO 2 reforming of CH 4 (DRM) can be represented by the following equation.…”
