Накратко на български

Зеолитите се изследват като катализатори за превръщане на въглеродния диоксид в горива и химикали, например в метанол или бензин. Това помага за намаляване на парниковите газове и намалява зависимостта на ЕС от изкопаемите горива.

ZEOlites for the conversion of CO2 to fuels and chemicals

Climate and pollution concern, feedstock availability and geopolitical issues stress the need for alternative sustainable processes for the production of chemicals and fuels. In this sense, the conversion of CO2 to valuable compounds containing more than one carbon is a grand challenge of our time. Among different strategies of using CO2 as a carbon feedstock, classic thermo-catalytic methods, should also be pursued, due to the simple recovery and recycle of solid catalysts able to work under high temperature and pressure conditions. Key however is to devise a process that is cost- and energy-efficient, while able to satisfy the rising demand of chemicals and fuels in a sustainable way. Although in its infancy, the direct hydrogenation of the CO2 to methanol combined with further C-C coupling into value-added products with two or more carbons is a very promising gas-to-liquid process. This direct strategy allows for the obtention of methanol, light olefins or gasoline, with a reduced number of steps and minimized chemical waste, and should help to reach fossil-fuel independency, relevant in EU, and the consumption of greenhouse gas, reducing its emissions at the source. Therefore, this integration can contribute to a more environmentally benign CO2 recycling strategy, i.e. CO2 as feedstock, as dictated by the EU environmental policy for ‘secure, clean and efficient energy’ through chemical transformation into high-volume added value products. In this fellowship, the introduction of different active sites, spatially isolated, but within the same solid matrix, would allow to carry out hydrogenation and C-C coupling with one catalyst. The rationale for the design and use of a new type of inexpensive, stable and catalytically active microporous hybrid zeolite for CO2-conversion is based on the design of novel multifunctional zeolites with tuned physico-chemical properties in an affordable way.

Цел на проекта

ZEOCO2 is a pioneering and structured effort to comprehensively study the introduction of well-positioned Zn, Cu and acidic catalytic active sites in zeolites to directly convert CO2 into fuels and chemicals in one step. This offers step economy due to the possibility of coupling the hydrogenation of CO2 with further C-C coupling within the same heterogeneous catalyst. The synthesis of cheap, stable and active zeolites with Zn sites incorporated in the framework generates Lewis acid sites and favours the positioning of Cu sites by ion-exchange. These Cu sites will deliver redox activity, while Al and Zn will yield acid sites, both needed in the tandem catalytic system. So far, the use of such bifunctional zeolites and especially core-shell structures have not been explored for the tandem process involving the consumption of CO2 and synthesis of gasoline or light olefines. Using a two-stage research methodology, ZEOCO2 will not only provide new hybrid zeolite synthesis technology to be used in acid and redox type processes, but also demonstrate the first direct CO2 to fuels/chemicals conversion within one solid catalyst.The combined expertise of the fellow and the host ensures the best chance for successfully completing the ZEOCO2 objectives in a mutually beneficial manner. On the one side, internal collaborations will allow access to state-of-the-art synthesis laboratories and train the researcher in catalysis engineering using gas-phase reactors in continuous mode; needed to prepare and test the novel zeolite catalysts. On the other hand, a secondment in a world-leading spectroscopy (applied to catalysis) research team, will allow to get new insights into the molecular nature of the active sites and provide understanding of the reaction mechanism and deactivation pathways of the catalysts.
