Hydrogen fuel production from sugarcane and its byproducts – a critical review

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The transition to a low‐carbon economy has intensified the search for sustainable hydrogen (H2) production routes. Sugarcane and its byproducts, such as bagasse, molasses and vinasse, have emerged as promising feedstocks due to their ready availability and renewable nature. However, comprehensive evaluations of the efficiency, limitations, and

Local sensitivity analysis of a supercritical extraction model

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...
