CO2 to light olefins conversion by cascade reactions over bifunctional nanocatalysts: an ‘all X-ray’ approach

In a waste-to-value perspective, CO2 can represent a sustainable carbon source to produce light olefins, representing key building blocks for petrochemical industry. CASCADE-X proposes an ultimate approach to directly convert CO2 to light olefins through cascade reactions over a bi-functional catalyst, obtained by integration of an active metal alloy for the CO2-to-methanol reaction with a zeolite/zeotype catalyst for selective methanol-to-olefins conversion. Such a single-reactor cascade approach enables a simplified process scheme while overcoming the thermodynamic restrictions of the methanol synthesis by its sequential conversion. The action aimed at generating fundamental knowledge on properties-performances relationships for the combined system, providing a rational for the optimization of catalyst and process conditions, as well as an improved understanding of key fundamental issues in both hydrogenation and methanol-to-olefins chemistry (restructuring, deactivation mechanisms, confinement effects). Integrating the applicant’s experience in X-ray spectroscopy and the Host’s excellence in structural analysis and testing of zeolite/zeotype catalysts, CASCADE-X also aimed at diversifying the researcher’s and Host individual competences and to promote trans-sectoral knowledge transfer. These goals have been pursued by an ‘all-X-ray’ approach, synergizing ex-situ/in situ/operando X-ray absorption spectroscopy and diffraction at large-scale synchrotron facilities level in combination with complementary laboratory-based physico-chemical methods, to obtain a detailed structural/electronic characterization of two ‘model’ PdZn/zeolite bifunctional catalysts.

Project objective

In a waste-to-value perspective, CO2 can represent a sustainable carbon source to produce light olefins, representing key building blocks for petrochemical industry. CASCADE-X proposes an ultimate approach to directly convert CO2 to light olefins through cascade reactions over a bi-functional catalyst, obtained by molecular scale integration of an active metal alloy for the CO2-to-methanol reaction onto a zeotype catalyst for selective methanol-to-olefins conversion. Such a single-reactor cascade approach enables a simplified process scheme while overcoming the thermodynamic restrictions of the methanol synthesis by its sequential conversion. The action will generate fundamental knowledge on properties-performances relationships for the combined system, providing a rational for the optimization of catalyst and process conditions, as well as an improved understanding of key fundamental issues in both hydrogenation and methanol-to-olefins chemistry (restructuring, deactivation mechanisms, confinement effects). These goals will be pursued by an ‘all-X-ray’ approach, synergizing in situ and operando X-ray absorption spectroscopy and diffraction/scattering at the laboratory and large-scale facility level in combination with complementary physico-chemical methods, to identify activity/selectivity/stability descriptors for the bifunctional catalyst. Multi-modal synchrotron nano-mapping of individual catalyst particles will elucidate the space-resolved dynamics of restructuring and deactivation phenomena. Integrating the applicant’s experience in X-ray spectroscopy, the Host’s excellence in structural analysis, testing and rational optimization of zeotype catalysts, as well as the industrial know-how of the private sector partner (a leading Company in recycling and manufacturing precious metal catalysts, where a Secondment is planned), CASCADE-X provides a unique platform to diversify the proponent’s individual competences and to promote trans-sectoral knowledge transfer.
