Decarbonizing the fertilizers sector: an alternative pathway for urea and nitric acid production
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
In order to alleviate the environmental impact that nitrogen fertilizers production is responsible for, several efforts have been addressed to incentivize the partial or total decarbonization of the supply chains of ammonia and its derivatives. The decarbo ...
2024Quantification of Native Lignin Structural Features with Gel-Phase 2D-HSQC0 Reveals Lignin Structural Changes During Extraction
Jeremy Luterbacher, Stefania Bertella
Our ability to study and valorize the lignin fraction of biomass is hampered by the fundamental and still unmet challenge of precisely quantifying native lignin's structural features. Here, we developed a rapid elevated-temperature H-1-C-13 Heteronuclear S ...
Wiley-V C H Verlag Gmbh2024New Polymers from Biomass-Derived Hydroxycinnamic Acid Derivatives
Polymers play a central role in shaping our world across various fields, but their heavy reliance on petrochemicals poses climate change, environmental and health risks. To address and alleviate these issues, transitioning to sustainable polymers, sourced ...
EPFL2024Selecting Suitable Near-Native Lignins for Research
There are several methods to isolate near-native lignins, including milled-wood lignin, enzymatic lignin, cellulolytic enzyme lignin, and enzymatic mild-acidolysis lignin. Which one is the most representative of the native lignin? Herein, near-native ligni ...
Washington2023Lignin Hydrogenolysis: Phenolic Monomers from Lignin and Associated Phenolates across Plant Clades
The chemical complexity of lignin remains a major challengeforlignin valorization into commodity and fine chemicals. A knowledgeof the lignin features that favor its valorization and which plantsproduce such lignins can be used in plant selection or to eng ...
AMER CHEMICAL SOC2023Direct conversion of lignin to functionalized diaryl ethers via oxidative cross-coupling
Paul Joseph Dyson, Mingyang Liu
Efficient valorization of lignin, a sustainable source of functionalized aromatic products, would reduce dependence on fossil-derived feedstocks. Oxidative depolymerization is frequently applied to lignin to generate phenolic mono- mers. However, due to th ...
2023Integrated production of urea and nitric acid in the pulp industry: techno-economic and environmental analysis of black liquor gasification-based processes
François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma, Meire Ellen Gorete Ribeiro Domingos
The pursuit of alternative energy sources for the nitrogen fertilizers sector has recently earned renewed interest due to increasing concerns regarding the world dependence on non-renewable energy resources and also motivated by the more stringent environm ...
2023Lignin, from biomass waste to sustainable materials for food packaging, antiviral coatings and agriculture
Our planet has been challenged for years by our reckless use of fossil fuels, which has led to the ongoing climate change and energy crisis. The transition to the use of renewable alternative sources has now became urgent and inevitable. The valorization o ...
EPFL2023Process modeling and integration of hydrogen and synthetic natural gas production in a kraft pulp mill via black liquor gasification
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
The black liquor gasification integrated to chemical plants has shown potential for reducing the process irreversibility and promoting the decarbonization of this industrial sector. In the integrated chemical plants proposed in this work, the purpose is co ...
2023Techno-economic and environmental analysis of high temperature heat pumps integration into industrial processes: the ammonia plant and pulp mill cases
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
Heat pumps will play an important role in improving the performance of the industrial processes aiming to decarbonize their heating requirements. Yet, defining the best operating conditions of those devices may be a challenging task, as they are embedded i ...
