Sustainable Conversion of Carbon Dioxide into Diverse Hydrocarbon Fuels via Molten Salt Electrolysis

Abstract: In recent decades, the unlimited use of fossil fuels mostly for power generation has emitted a huge amount of carbon dioxide in the atmosphere which in return has led to global warming. Here we use green technology, the molten salt electrochemical system comprising of titanium and mild steel as a cathode with graphite anode whereas molten carbonate (Li2CO3-Na2CO3-K2CO3; 43.5:31.5:25 mol%), hydroxide (LiOH-NaOH; 27; 73 and KOH-NaOH; 50:50 mol %) and chlorides (KCl-LiCl; 41-59 mol%) salts as electrolytes This st… Show more

“…M 2 CO 3 and MOH can both be regenerated by reacting M 2 O with the further supplied CO 2 and H 2 O, respectively (eq ). However, research in the past several years seems to focus more on improving the carbon production efficiency by adjusting the molten salt composition, while a deep understanding of the mechanism for the influence of molten salt composition on the gas behavior at the electrode/electrolyte interface is lacking. ,, M 2 CO 3 + 4 MOH 3 M 2 O + CH 4 + 2 O 2 false( normalM = normalLi , normalNa , normalK false) 3 M 2 O + CO 2 + 2 H 2 O M 2 CO 3 + 4 MOH CO 2 + 2 H 2 O CH 4 + 2 O 2 …”

“…Molten carbonate electrolysis offers an efficient route to convert CO 2 or carbonate to C/CO at a rapid rate and high product selectivity without using rationally designed catalysts to overcome the kinetic barrier. Currently, most molten carbonate eletrolyzers employ lithium-containing salts due to the thermodynamic favorability of Li 2 CO 3 , relatively low eutectic temperature, and adequate solubility of Li 2 O. However, lithium resource is limited in the Earth’s crust (e.g., lithium’s reserve is only less than one-thousandth of that of calcium in the Earth’s crust, Figure a) and will become scanter with increasing demand for lithium-based energy-storage devices. Thus, exploiting lithium-free molten carbonate electrolyzers is of great importance to expand the novel systems and achieve the practical viability of molten carbonate electrolysis.…”

“…It usually refers to capturing carbon emissions from burning coal and storing them under the earth. If coal enterprises could produce clean coal to fulfil low-carbon development upstream, it would reduce the pressure on downstream manufacturing to reduce carbon emissions, as seen, for example, in the practice of molten salts [13] or the torrefaction of biomass as a renewable alternative fuel to coal during co-firing [14]. Clean coal technology is already being heavily promoted in the United States-the Obama Administration invested $84 million in clean coal technology.…”
