Processing factors affecting roughness, optical and mechanical properties of nanocellulose films for optoelectronics
This work aims to understand how nanocellulose (NC) processing can modify the key characteristics of NC films to align with the main requirements for high-performance optoelectronics. The performance of these devices relies heavily on the light transmittan ...
Elsevier Sci Ltd2024Electrospun zein incorporating phycocyanin and Spirulina extract: Fabrication, characterization, and potential application
Electrospinning was used to develop zein fibers containing phycocyanin and aqueous-ethanolic extract of Spirulina (AEES) for elucidating the potent packaging properties of phycocyanin and AEES on walnut samples. Morphological results revealed that using th ...
Amsterdam2023Integrated production of chemicals and fuels in the pulp industry: techno-economic and environmental analysis of black liquor gasification-based processes
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
The pulp and paper sector is classified as an energy intensive activity and several efforts are being made to mitigate its atmospheric emissions, improve the recovery of residual heat and capitalize on its byproducts. The black liquor (BL) is a byproduct o ...
2022Techno-economic and environmental analysis of methanol and dimethyl ether production from syngas in a kraft pulp process
The conventional configuration of a pulp mill, in which black liquor is concentrated and burnt, is compared to the upgrading gasification routes for methanol (MeOH) or dimethyl ether (DME) co-production. To this end, various exergy-based and environmental ...
PERGAMON-ELSEVIER SCIENCE LTD2022Diformylxylose as a new polar aprotic solvent produced from renewable biomass
Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick
Lignin is a promising candidate for the replacement of fossil-based materials, due to its natural abundance and aromatic structure. This same structure poses major challenges to lignin's exploitation for material development. The harsh conditions generally ...
2021Exergy and environmental analysis of black liquor upgrading gasification in an integrated kraft pulp and ammonia production plant
Daniel Alexander Florez Orrego
The black liquor is a byproduct of the kraft pulping process that contains more than half of the exergy content in the total woody biomass fed to the digester, representing a key supply of renewable energy to the pulping process. In this work, the conventi ...
2021Production and characterization of stabilized lignin
Lignocellulosic biomass is a sustainable source of renewable carbon, and it is the most abundant form of terrestrial biomass. The three main constituents of lignocellulosic biomass are cellulose, hemicellulose, and lignin. The monomers from these biopolyme ...
EPFL2019Potential of hydrothermal black liquor gasification integrated in pulp production plant
François Maréchal, Maziar Kermani, Julia Granacher, Ayse Dilan Celebi
Greenhouse gas emission mitigation is one of the main motivations for increasing the use of biomass in providing environmentally friendly value-added products. The pulp and paper industry is a promising sector for the integration of biorefinery pathways. A ...
Silesian University of Technology2019A novel MILP approach for simultaneous optimization of water and energy: Application to a Canadian softwood Kraft pulping mill
François Maréchal, Maziar Kermani, Zoé Périn-Levasseur
An optimization methodology based on Mixed Integer Linear Programming (MILP) has been developed for simultaneous optimization of water and energy (SOWE) in industrial processes. The superstructure integrates non-water process thermal streams and optimizes ...
