Beyond electrolysis: old challenges and new concepts of electricity-driven chemical reactors

Abstract

With renewable electricity becoming the most widely available, versatile energy form on Earth, the electricity-driven chemical reactors will play crucial role in the transition to green, environmentally-neutral manufacturing of fuels and chemicals.

Mechanistic and multiscale aspects of thermo-catalytic CO2conversion to C1products

“…Steady and consistent power supply, thermo-mechanical and physical properties of materials, and energy efficiency represent the main challenges when considering electrified reactors. [458][459][460] Besides heat management, thermodynamics is an intrinsic limit of some of these processes. To increase thermodynamic equilibrium yields, suitable pressure and temperature should be chosen, but convenient designs help to achieve good yields with less severe operating conditions (e.g., lower Catalysis Science & Technology Mini review pressure).…”

Catalyst Heating Characteristics in the Traveling-Wave Microwave Reactor

“…The increasing attention towards reducing greenhouse gas emissions and government's efforts in promoting policies to meet the Paris Agreement are the driving forces to change the chemical industry [1][2][3]. In this regard, electrification of chemical processes is one of the most promising transition pathways to low carbon footprint [4]. However, it is also accepted that even using state-of-the-art technologies, some processes, such as high-temperature processes, cannot be performed efficiently using electric heating.…”

Cavitation intensifying bags improve ultrasonic advanced oxidation with Pd/Al2O3 catalyst

“…Sonochemical reactors have been identified as an effective tool to influence reaction mechanisms and its rate, due to the large amount of energy released, accompanied by the generation of free radicals, and enhanced mass transfer in multiphasic systems (gas–liquid and liquid–solid) [11] . Unfortunately, the low energy efficiency of most sonochemical systems, and the complex interdependence of several parameters leading to reproducibility issues have prevented a wider adoption by the industry [12] , [13] .…”
