Although good catalysts for nODH of alkanes have already been provided, there is still a need of additional ones with high catalytic conversion, activity and selectivity, and/or with a catalytic conversion. The selection of certain metals in combination with other elements, all of them stabilized with particular organic compounds and adsorbed on porous supports, gave rise to highly active catalytic surface areas that, in addition, not only are selective for propene selectivity in nODH, but also are highly stable and free from the main drawbacks of other catalysts for the same reaction (i.e. coke formation, by-side deactivating reactions, etc.).
The methodology on the scope of the proposed CWA ‘Valorization of light hydrocarbons. One-pot method for the preparation of nanocatalysts for non-oxidative dehydrogenation (nODH) of light alkanes’ describes a process for the preparation of a catalyst composition as defined above. By means of this one-pot synthesis method, these catalysts are highly active due to the small-variation of the surface areas caused by the homogeneous distribution of the elements on the supports, and due to the synthesis of well-dispersed nanoparticles (1-15 nm, more particularly 1-5 nm), controlled by the presence of an organic molecule. The one-pot reaction runs at relatively low temperatures (room temperature to 100 ºC), thus making the production process more affordable and reproducible than other methods for obtaining similar catalysts. The use of this method for the preparation of the catalysts results in lower reaction temperature (≈500 °C), higher selectivity to propylene (>99%) and higher conversion and stability (up to 23% and maintained at 21% after 24 h on stream) The one-pot organometallic approach allows to explore new horizons in the preparation of other catalyst for propane dehydrogenation with a very easy one-step methodology.
This workshop is an initiative of the European research and innovation BIZEOLCAT project (Bifunctional Zeolite based Catalysts and Innovative process for Sustainable Hydrocarbon Transformation). This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 814671. BIZEOLCAT's main objective is to obtain light olefins and aromatics using light hydrocarbons (C1, C3 and C4) by implementing new procedures, involving innovative catalysts synthesis methodologies and novel reactor design and processing, demonstrating their improvement in sustainability and economic scalability in existing industrial processes.
The kick-off meeting will be held on 5 October 2022, from 10:00 to 12:00 CET as online meeting. People interested to participate in the kick-off meeting can register through the form below.
