Zeoliten diskriminazioa olefinak ekoizteko CO2-aren hidrogenazioaren bitartez

Abstract

Among climate change technologies, carbon capture and utilization will play a key role. In this line, olefins synthesis (value-added product used for plastics production) from CO₂ is a mandatory step. In this work, the CO₂ hydrogenation into olefins were assessed. Specifically, the role of the catalysts in processes with methanol as intermediate. SAPO-11, -18, -34 and HZSM-5 zeolites were analyzed, paying special attention to their structure and acidity. SAPO-34 is best suited to achieve a remarkable olefin yield and high selectivity (>75%) when used together with In₂O₃-ZrO₂ catalysts.
