💡#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

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.

Alhamdulillah 😊 I am delighted to share that our collaborative research article " Catalytic bi-reforming of methane as a potential source of hydrogen rich syngas: Promotional effect of strontium on the catalytic performance of Ni/MgO-ZrO2” Published in "Energy Conversion and Management: X (IF= 6.3)" #methane #hydrogen #syngas #catalysis

#QTNano: The rational use of non-renewable energy sources such as methane (CH4) has been considered a promising alternative to several high-value chemicals. Therefore, there is a considerable effort to identify the main physical-chemical features for modulating CH 4 dehydrogenation, in particular, at the nanoscale regime, where new effects could promote the breaking of the C–H bond. https://lnkd.in/ez9FETc

Green hydrogen (H2) produced through the water electrolysis has been considered as one of the most riveting alternatives to replace the contemporary fossil fuel energy framework. However, the efficiency of H2 production through water electrolysis faces challenges, particularly in the anodic oxygen evolution reaction (OER), where sluggish reaction kinetics hinder progress. In our recent research article published in Applied Catalysis B: Environment and Energy, we demonstrated a hydrazine-assisted overall water splitting (HzOWS) system, where we replaced oxygen evolution reaction (OER) with hydrazine oxidation reaction (HzOR) coupled with hydrogen evolution reaction (HER) to improve the energy-efficiency of overall water electrolysis system. To trigger this electrolysis process, we utilized a transition metal phosphides (TMPs) based nanocrystals engineered with dopant induced hollow structure as a result of Kirkendall Effect that acts as bifunctional electrocatalysts for both HzOR and HER. We have also demonstrated a proof-of-concept, solar-energy driven hydrazine assisted H2 production using commercial Si solar panel with a stable photocurrent density of 12.1 mA/cm2. Our work opens a new avenues for the design & development of catalysts for energy-efficient hydrogen production and valuable chemical products as well as provides an substantial potential for practical applications including solar-energy driven electrolysis.
