Happy to share our latest work just published in Separation and Purification Technology. "Effect of Li-Na sorbent phase in Ru/Al2O3 Dual Function Materials for the Integrated CO2 Capture and Methanation" Stefano Cimino, Elisabetta Maria Cepollaro, Francesco Frusteri, Luciana Lisi CNR-STEMS, CNR ITAE Available here (open access): https://lnkd.in/d_2Ra69n This work is dedicated to our co-author, friend and colleague Dr. Francesco Frusteri who suddenly passed away on April 2024. We would like to pay a tribute to his remarkable contributions to the heterogeneous catalysis community as a committed researcher and distinguished scientist. To many of us he was a desired companion of scientific and social life of conferences and congresses. The design of highly performing dual functional materials (#DFM) is the key to the successful deployment of Integrated Carbon Capture and Methanation (#ICCM) process that combines both steps into a single unit operation with high energy efficiency. Intending to enhance the CO2 working capacity while preserving high catalytic #methanation activity, herein we set out to investigate the effect of combining Li and Na as the CO2 sorbent phase in Ru/Al2O3 DFMs. ICCM tests in a fixed bed reactor operated with alternate feeds indicated that combining Na with Li effectively increases the CO2 capture capacity and methane production. However, this generally requires higher temperatures to properly activate the catalytic methanation and to regenerate the DFM compared to a pure Li-based formulation. Transient operando #DRIFTS and catalytic kinetic experiments provided mechanistic insights into the activation/inhibition of different reaction paths on those DFMs containing only Li and/or Na.

Excited to share our latest research on ammonia (NH3) combustion kinetics! 🚀 📢 Sanket G. and co-authors conducted a comprehensive evaluation of 16 recent NH3 combustion kinetic models, utilizing vast amounts of available experimental data on NH3 and NH3/H2 mixtures. 🔬 This study provides valuable insights into the overall performance of these models, aiding users in selecting the most appropriate one for their needs. Additionally, we identified key kinetic parameters and explored their potential for model improvement. This work lays the groundwork for developing a consolidated model that integrates insights from various kinetic modeling approaches, as well as theoretical and experimental data. Our goal is to deepen the understanding of NH3 combustion, driving future advancements in sustainable energy solutions. 🌱 Explore the full study through the link in the comments! 🔗   #fsc #rwth #fuelscience #fuelsciencenter #aachen #university #clusterofexcellence #innovation #sustainability #ZeroCarbon #NetZero #AmmoniaCombustion #HydrogenCombustion

Ammonia Fueled Solid Oxide Fuel Cell (SOFC): Cell to System Level To effectively develop a technology, it is crucial to understand its various aspects and levels to ensure its reliability and efficiency. 🌱 We have developed a multiscale, multiphysics approach to address different levels of ammonia-fueled SOFCs, encompassing the cell, stack, and system levels. Two types of cells, designed for operation at low and high temperatures, are compared. Various ratios of ammonia pre-checking are investigated to prevent nitriding degradation. 🔬 You can check more results in our research paper "Multiscale multiphysics modeling of ammonia-fueled solid oxide fuel cell: Effects of temperature and pre-cracking on reliability and performance of stack and system" published in Applied Energy, 373, 123913(2024)! 🚀 I would like to express my sincere gratitude to the co-authors and my colleagues at DTU Energy and AMON Project EU for their support and collaboration.

👏🏼That's a fascinating statistic! The prevalence of cast iron in European gas grids highlights the importance of understanding hydrogen diffusion and embrittlement in these materials. 👆🏼The focus on societal awareness of material degradation issues is crucial. Corrosion can have significant economic and safety implications, and it's essential that we continue to research and develop solutions to mitigate its effects. 🙌🏽We're proud to be part of the CANDHy project and to support the valuable work of researchers like Prof. Cabrini.

https://lnkd.in/dJKz3E5u A research project to establish decarbonization technologies for the steelmaking industry, in which Primetals Technologies is an associated partner, has been awarded a €1.8 million research grant from the European Union (EU) via the Research Fund for Coal and Steel (RFCS). The program aims to establish a process for injecting hydrogen using the Sequence Impulse Process (SIP) technology directly into the blast furnace via the shaft. In addition to the grant, contributions will be made by each of the research partners, bringing the total project value to €3.5 million.

A revolutionary turbomachinery concept, which could be the catalyst needed to enable rapid scale-up of low-carbon hydrogen technology.    Dylan Rubini, Nikolas Karefyllidis and Budimir Rosic from University of Oxford, Liping Xu from University of Cambridge and Elina Nauha from Coolbrook Oy present a broadened scope of application for a revolutionary concept. The concept is referred to as the turbo-reactor, and has the potential to replace gas-fired radiant furnaces and decarbonise a wide range of hard-to-abate, high-temperature endothermic chemical reaction processes. Based on the authors new investigations there are potential applications for a variety of energy-intensive chemical processes, including those used for hydrogen production.   Read the full journal paper at the Open Access GPPS Journal.   https://lnkd.in/epE2aV-5    #CompressorAerodynamics, #ChemicalReactions, #CFD, #TurboReactor, #RotordynamicReactor, #TurbomachineryDesign

💡 Did you know that the non-steel metallic distribution gas grid materials cover 49.406 km of the total length of the European gas grid with 34% being made from ductile cast iron and 41% of grey cast iron? 🔬 The information derives from CANDHy preliminary results and in this context our project partner Prof. Marina Cabrini from the University of Bergamo participated in the European Corrosion Congress – EUROCORR 2024 making a short presentation focusing on the subject of hydrogen diffusion and embrittlement of cast iron. 🌐This year’s #EUROCORR2024 under the theme “A step forward in societal awareness of material degradation issues” took place in Paris in early September bringing together corrosion experts from universities, research associations and the industry to address all aspects of corrosion science, technology, and engineering.

No parece fácil de escalar, construir y mantener, pero el concepto es genial "The innovative design of the turbo-reactor is fundamentally based on converting all of the imparted mechanical energy into internal energy, rather than pressure. This enables temperatures of up to 1,700°C to be achieved within an axial length on the order of one metre, resulting in an increase in the power density of 50 to 1,000 times compared to a surface heat exchanger"
