Descripción del proyecto
Una ruta versátil para producir olefinas valiosas
La dimerización es un proceso en el que dos moléculas de composición química similar reaccionan entre sí para formar un dímero. Una investigación ha demostrado que tanto la estabilidad catalítica como la selectividad en la dimerización de alquenos en sitios basados en níquel mejoran cuando los estados de transición de los pasos elementales son solvatados por líquidos no polares. El objetivo del proyecto Pores4Olefins, financiado por las Acciones Marie Skłodowska-Curie, es comprender mejor los efectos de la solvatación en la dimerización de alquenos en sitios con base de cobalto, mejorando el conocimiento de sus consecuencias cinéticas y mecánicas mediante un enfoque de métodos mixtos. La investigación del proyecto podría proporcionar una forma versátil de producir olefinas de valor añadido y productos químicos relacionados, con aplicaciones prometedoras en la industria del petróleo y, especialmente, en las futuras biorrefinerías.
Objetivo
This fellowship aims at establishing the researcher as an expert in the field of heterogeneous catalysis—becoming an independent leader researcher in the EU—through interdisciplinary scientific (e.g. chemical engineering, organic and inorganic chemistry, materials and surface science) and transferable skills training (e.g. project management). The researcher, Dr. Jorge Quesada, will join the LSAC research group at UC Berkeley (USA) under the supervision of Prof. Enrique Iglesia, and will be reintegrated (EU) into the CRC research group at the Universidad de Oviedo (Spain) under the supervision of Prof. Salvador Ordóñez.
Recent findings in LSAC have demonstrated that both the catalytic stability and selectivity in the alkene dimerization on Ni-based sites are enhanced when the transition states of the elementary steps are solvated by non-polar liquids. The liquid phase is formed at the reaction temperature by capillary condensation of the solvent molecules within the pores of the material used as the active sites support. This project proposes to augment the understanding of the solvation effects on the alkene dimerization on Co-based sites—by building knowledge on their kinetic and mechanistic consequences through a mixed-methods approach—and translational research that leverages these results to other similar C-C bond forming reactions of alkenes—metathesis and hydroarylation on Mo- and Ni-based sites, respectively. This technology strategy would allow the combination of ethene dimerization and metathesis resulting in an industrial one-pot ethene-to-propene process of significant potential impact—the project engages an industrial collaborator by an intersectoral secondment. This research is likely to provide a novel versatile technology for the production of value-added olefins and related chemicals, with promising applications in the current oil industry and, especially, in future biorefineries; therefore, having a positive impact on the EU society and competitiveness.
