Abstract The use of green renewable energy to convert carbon dioxide (CO 2 ) into valuable chemicals and fuels through CO electrolysis technology (also known as electrochemical reduction reaction, eCO RR) is an advantageous technology, which could greatly aid the global carbon‐neutral goal. Although progress has been made in alkaline/neutral media, low conversion efficiency target products, carbonate/bicarbonate salt precipitation, blockage electrode holes caused by are not conducive industrial applications. Acidic media address these issues; however, conditions, there other challenges that need be addressed, such hydrogen evolution, poor tolerance electrocatalysts, electrolysers. This review discusses recent advances industrial‐level acidic electrolysis, including reaction mechanisms, device design, aiming promote its commercialization. In addition, a comprehensive evaluation strategy RR system proposed, perspectives provided based on related discussion.

In the electrochemical synthesis of hydrocarbon gases from CO2, improvement selectivity product by controlling composition electrolyte is attractive as a process that does not require complex electrode structures; however, little known about conversion CO2 at ionic liquid-based electrolyte/metal interface. this study, and H2O to C2 C3 hydrocarbons on pure Ag in N, N‑diethyl-N-methyl-N-(2-methoxyethyl) ammonium tetrafluoroborate (DEME-BF4) containing metal hydroxides, such Ca(OH)2, NaOH, CsOH, was investigated. Quantitative gas analysis samples obtained potentiostatic electrolysis for 30 min melt with DEME-BF4:H2O:Ca(OH)2 molar ratio 2:1:1.8 × 10−4 room temperature demonstrated C2H4, C2H6, C3H6, C3H8 were produced, current efficiency determined be 11.3 %. The reactant HCO3− coordinated DEME+, BF4−, Ca2+ ions, identified Raman spectroscopy combined density functional theory (DFT) calculations. Moreover, surface-enhanced spectroscopic data revealed intermediate during adsorbed 2CO− interacting ions. DFT simulations also increased energetic stability 2CO−. This study showed tailoring can lead molecular-level changes phase transformation bulk solution electrode/ionic liquid interface proposed enables unique C3.

The main goal of traditional methods for sweetening natural gas (NG) is to remove hydrogen sulfide (H2S) and significantly lower carbon dioxide (CO2). However, when NG processes are integrated into the capture storage (CCS) framework, there potential synergy between these two technologies. A steady-state model utilizing a hybrid solvent consisting N-methyl-2-pyrrolidone (NMP) monoethanolamine (MEA) has been developed successfully anticipate CO2 H2S process from NG. was tested against important variables affecting performance. This article specifically explores impact operational parameters such as lean amine temperature, absorber pressure, flow rate on concentrations in sweet reboiler duty. result shows that solvents (MEA + NMP) perform better removing acid gases reducing duty than conventional chemical MEA. primary purpose meet product requirements while consuming least energy possible, which line with any plant's efficiency goals.
