Fly ash as a cost-effective catalyst to promote sorbent regeneration for energy efficient CO2 capture

Energy, Год журнала: 2024, Номер 294, С. 130890 - 130890

Опубликована: Март 3, 2024

The use of catalysts to promote sorbent regeneration is currently considered an effective method reduce the energy required in CO2 capture processes. Aiming at identifying stable and cost-effective with high desorption efficiency, here we investigated performance fly ash (FA) during thermal aqueous amine solutions. rate, cyclic capacity heat duty a CO2-saturated ethanolamine addition FA were experimentally measured, results compared those obtained for same solution without eight different catalysts. Experimental showed that significantly improved non-catalyzed system, was most efficient these. Further studies temperatures provided comparable system least 5 °C higher always reduced temperature, especially beginning process. Finally, recycling tests demonstrated had good stability its catalytic efficiency remained even after 20 cycles. In conclusion, could be catalyst energy-efficient capture, deserving further investigation application industrial-scale plants.

The use of solid acid catalysts for sorbent regeneration is an emerging approach to improve the energy efficiency CO2 capture processes. In this study, fly ash (FA), industrial byproduct rich in acid/base sites, was chosen as a support material SO42−/ZrO2 (SZ) preparation SZ@FA composite catalysts. Three with different mass ratios between SZ and FA were synthesized evaluated process at 88 °C CO2-saturated MEA solution. Their desorption performance, expressed rate, amount desorbed, heat duty, then compared that obtained unmodified FA, ZrO2, absence (blank), under identical operating conditions. Compared uncatalyzed system, showed significantly better performance. particular, SZ@FA-1/2 provided highest values rate cyclic capacity while reducing consumption by 45.4% blank system. It also demonstrated stability over 20 consecutive absorption-desorption cycles. Comparison other reported highlighted high performance SZ@FA-1/2, particularly terms relative duty reduction, positioning it cost-effective environmentally friendly choice post-combustion applications.

The excessive energy consumed restricts the application of traditional postcombustion CO2 capture technology and limits achievement carbon-neutrality goals. Catalytic-rich amine regeneration has potential to accelerate proton transfer increase efficiency in separation process.
