| description | <p dir="ltr">In this work, sequential incipient wetness impregnation method was used to synthesize Cu/Al<sub>2</sub>O<sub>3</sub>, Cu/Na<sub>2</sub>O/Al<sub>2</sub>O<sub>3</sub> and Cu/CaO/Al<sub>2</sub>O<sub>3</sub> catalysts in different compositions for CO<sub>2</sub> conversion to value-added products. Synthesized catalysts were characterized using various analytical techniques and their performances for CO<sub>2</sub> catalytic conversion were tested in a high-pressure packed bed reactor under reaction conditions of P = 60 bars, T = 300 °C, and H<sub>2</sub>/CO<sub>2</sub> = 3. The obtained results revealed that the type of adsorbent had a significant impact on CO<sub>2</sub> conversion, with CaO-containing catalyst being more efficient for methanol selectivity. Increased Cu content from 10 wt% to 30 wt% with fixed CaO content of 10 wt% resulted in a small increase in CO<sub>2</sub> conversion where the highest CO<sub>2</sub> conversion of 16.44% and the highest methanol selectivity (17.75%) were obtained for catalyst containing 20 wt% of copper. The best performing catalyst was further promoted using 0.5 wt% Rh promoter which improved both methanol selectivity and space time yield to 23.2% and 0.08 g<sub>MeOH</sub>g<sub>cat</sub><sup>−1</sup>h<sup>−1</sup>, respectively. The comparative high performance of the Rh-promoted catalyst was attributed to smaller metal oxide particle size with uniform dispersion, presence of effective hydrogen spill over, moderate basic sites, surface defects and presence of induced copper species.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Environmental Chemical Engineering<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.jece.2024.112325" target="_blank">https://dx.doi.org/10.1016/j.jece.2024.112325</a></p> |
