In this study, an energy, exergy, and environmental (3E) analyses of a plasma-assisted hydrogen production process from microalgae is investigated. Four different microalgal biomass fuels, namely, raw microalgae (RM) and three torrefied microalgal fuels (TM200, TM250, and TM300), are used as the feedstock for steam plasma gasification to generate s...
Three-dimensional concrete printing (3DCP) is a fast-evolving manufacturing technique in the construction industry with numerous advantages over traditional construction methods. Nevertheless, many unknowns about 3DCP in the manufacturing stage still remain, such as the maximum number of printed layers before failure or the maximum speed at which a...

Biomass utilization is facing great challenge mainly due to the low profit margin of biomass products. Bio-energy plants using gasification and liquefaction technologies are barely surviving, while biomass to activated carbon (AC) route has been demonstrated economically successful. In this work, spent mushroom substrate was used to produce AC and ...
A mesure que l'intérêt mondial pour les énergiesrenouvelables s'intensifie, la production de biogaz ne cesse de croître,car elle est une source renouvelable et propre. La technologie deséparation par adsorption modulée en pression (Pressure SwingAdsorption ou PSA) se présente alors comme une des technologiesintéressantes permettant la valorisation ...

The solubility of NaCN and Na2CO3 in the water–ethanol mixture was determined through experiments. Also the polynomial fit was used to lead to the relationship between the solubility of NaCN/Na2CO3 and the solvent composition. In the meantime, the solvent molecular-electrolyte pair interaction parameters of electrolyte NRTL (eNRTL) model were estim...

The advancements in second-generation bioethanol produced from lignocellulosic biomass, such as crops residues, woody crops or energy grasses are gaining momentum. Though, they are still representing less than 3% of total bioethanol production, the GHG reduction potential is higher than for 1G-bioethanol. The environmental impacts of bioethanol pro...

This paper focuses on optimizing the shape of prefabricated building components that are produced using 3D concrete printing (3DCP) techniques. The proposed method is to improve the structural and thermal properties using heuristic optimization algorithms, as such that they meet the minimum standards determined by building design codes. First, a ca...
Laser Powder-based Directed Energy Deposition (LP-DED) process is a cutting-edge Additive Manufacturing (AM) technology for metal part repair and production. The disruptive potentialities of LP-DED are nowadays limited by the difficulty in the identification of the optimized set of process parameters, typically obtained from long and expensive expe...
