Abstract:
Addressing the critical issue of rising atmospheric CO₂ concentrations and their impact on global climate change requires innovative technological solutions. This study introduced a novel and sustainable method for the production of ethylene glycol, commonly used in antifreeze, polyester manufacturing, and various industrial applications. Unlike conventional methods relying on coal or biomass-derived resources, our proposed method employed electrochemical CO₂ reduction, significantly decreasing environmental impacts. Central to this process was the innovative "OCEAN" technique, which strategically utilized oxalic acid as a key intermediate, enhancing overall conversion efficiency and minimizing undesirable byproducts. The proposed methodology involved a sequential procedure comprising electrochemical CO₂ reduction followed by catalytic hydrogenation steps. Initially, CO₂ was electrochemically converted into oxalic acid with a conversion efficiency of approximately 74.663%. Subsequently, oxalic acid was hydrogenated to glycolic acid, achieving around 56.715% conversion efficiency. In the final stage, glycolic acid underwent hydrogenation to produce ethylene glycol, attaining a high conversion efficiency of 84.878% and a product purity of 96.011%. Compared to conventional methods for ethylene glycol production, such as coal-based synthesis or biomass conversion, the "OCEAN" technique demonstrated superior conversion efficiencies and reduced environmental impact. Furthermore, this method achieved a 93.716% ethylene glycol yield, outperforming several previously reported methods with typically lower efficiencies. Collectively, this integrated approach enabled a substantial reduction of CO₂ emissions by approximately 62.631%, providing a cleaner, sustainable, and economically viable alternative for industrial chemical manufacturing
