논문 초록 (Abstract)
The aldol condensation of low-molecular-weight biogenic carbonyl compounds is a crucial step in producing longer-chain intermediates for sustainable aviation fuel (SAF) synthesis. In this study, we developed shaped LaCeOx catalysts to enable an efficient continuous aldol condensation process of furfural and acetone. Three structured catalyst configurations were evaluated: (i) compressed LaCeOx powder formed into disk granules, (ii) pelletized LaCeOx with a bentonite binder, and (iii) a LaCeOx-coated metal foam monolith. While the disk and pellet catalysts suffered from mechanical degradation and pore blockage from byproduct polymerization, the metal form catalyst maintained its structural integrity and exhibited superior productivity. This enhanced performance is attributed to the metal foam’s open porosity, which improves mass transport and minimizes undesired side reactions. Furthermore, the metal form catalyst demonstrated excellent regenerability via air calcination at 673 K, highlighting its potential for long-term operation. Integrating of the optimized aldol condensation with a downstream hydrogenation/hydro-deoxygenation step yielded an aviation fuel precursor with an overall of approximately 39%, underscoring the scalability and feasibility of this approach for SAF production.
