Here is the raw material we work with: #molecules. Chemical entities that make up the different gases. And our aim is to provide equipements and solutions that are not only compatible but specialised for each one, being able to concretely support the use and diffusion of each existing type. Wherever gas is used, we are there. Discover more: https://lnkd.in/egU9NNuE #gases #innovation #energy

Happy to share our latest work published in the International Journal of Hydrogen Energy, titled "Novel Ni–Ru/CeO2 catalysts for low-temperature steam reforming of methane". Abstract Upgrading of #biogas and #biomethane into #H2-rich streams by #steam_reforming is regarded as an effective strategy to reduce fossil fuel consumption contributing to the transition towards a #green_energy system. In this context, novel reactor configurations such as #membrane_reactors appear a promising route for #process_intensification, but they require novel catalysts more active at low temperatures, stable, and resistant to coke formation. In this work, we prepared and tested structured catalysts characterized by a low Ni content (7 wt%) and a very low Ru content (≤1 wt%) supported on ceria and deposed onto SiC monoliths. Catalysts were tested at low temperatures (<600 °C), i.e. at temperatures suitable for applications in Pd-based membrane reactors. Fresh and used catalysts were characterized by ICP-MS, N2 physisorption, XRD, TEM, SEM-EDS, XPS and H2-TPR to identify the physicochemical properties affecting the catalytic activity. The catalysts showed good activity towards methane reforming, stable performance, and good resistance to coke formation. Ruthenium affects both the intrinsic catalytic activity and the resistance to the inhibiting effect of steam on the reaction rate. This is related to improved redox properties due to the intimacy between the active metals and their strong-metal-support-interaction with the ceria. Finally, our catalysts show self-activation under reaction conditions, which is an interesting property for applications. This is a joint work between CNR-STEMS and CNR ITAE, co-authored by Giovanna Ruoppolo, Almerinda Di Benedetto, Antonio Vita, Cristina Italiano, MINJU THOMAS, Giulia Sorbino, and myself and funded within the framework of PLUG-IN Project.

Antoni Llobet and group report a new molecular hybrid material Fe-A2B2 porphyrin to enable the generation of CO and conversion to C2+ products. The as-prepared Fe-A2B2 porphyrin has two quaternary ammonium groups and two thiolate substituents, which facilitate tandem catalysis and stability. The proposed catalysts have achieved 50% of FE for ethylene and 77% for C2+ products at an applied potential of -1.05 V vs RHE. 

A recent report by DECHEMA (https://lnkd.in/dzzy67iy) shows how Power-to-X (PtX) provides a #sustainable solution to produce molecules by combining electrolysis with CO2 capture #technologies from different industries.  The graphic below shows how CO2 can be valorized into different feedstocks. The primary hydrocarbon production pathways for PtX include methanol synthesis, Fischer-Tropsch process (sustainable aviation fuels, waxes, naphtha), Sabatier Process (methane), dimethyl ether (DME), and others.

Happy to share a recent collaborative paper on the photocatalytic production of ethylene from ethane (https://lnkd.in/evC4q-Py). This work was completed during my post-doc in Christos Maravelias lab, and it is part of a large collaboration with the Solar fuels group led by Prof. Geoffrey Ozin at the University of Toronto. While there are still significant challenges to be solved before this system can be profitable, it is really interesting to see that solar technologies do offer a pathway to redesign the chemical industry. A concept that we keep exploring in this paper is that one of an LED refinery to overcome intermittency and variability associated with natural sunlight.

💡#PBR - Plasma-Boudouard-Reactor: What Does It Mean?💡 Our CAPHENIA #technology combines three steps into one seamless process inside our PBR. We’ll break down these steps to explain how the Plasma-Boudouard-Reactor works, which leads to industry-leading efficiency through its 3-in-1 zone reactor.⚡ 1️⃣ Plasma zone The heart of the CAPHENIA process is the high-temperature plasma zone. At around 2000°C, methane (CH₄) is broken down into carbon (C) and hydrogen (H₂). 2️⃣ Boudouard zone In the Boudouard zone, the carbon (C) from the plasma zone reacts with carbon dioxide (CO₂), producing carbon monoxide (CO). This reaction fully harnesses the heat energy from the plasma process and converts it into chemical energy. 3️⃣ HetWGS Zone In the heterogeneous water-gas shift (hetWGS) zone, the remaining carbon (C) reacts with water vapor (H₂O), producing more carbon monoxide (CO) and hydrogen (H₂). This step allows flexible control over the composition of the resulting synthesis gas (CO + H₂). 🎬Check out our video of the delivery and installation of our PBR on LinkedIn: https://lnkd.in/dS9x7Yd6 📲Learn more about us and technology on our website (link in comments section)! #Cleantech #FuelingtheFuture #Innovation #SAF
