Aqueous phase reforming (APR) of glycerol over platinum supported on Al2O3 catalyst
(2016)The glycerol's APR reaction over 5% Pt/Al2O3 catalyst for H2 production in a batch reactor is investigated in the present work. The effect of the operating parameters, such as the: i) reaction time, ii) operating temperature, ... -
Crude bio-glycerol aqueous phase reforming and hydrogenolysis over commercial SiO2Al2O3 nickel catalyst
(2016)In the present work, an one-pot Aqueous Phase Reforming (APR) and Aqueous Phase Hydrogenolysis (APH) of crude glycerol in a batch reactor containing commercial SiO2Al2O3 supported 65%Ni catalyst is performed. The effect ... -
Development of sodium propionate-based deep eutectic solvents for polyphenol extraction from onion solid wastes
(2019)Abstract: The objective of the study presented herein was the optimisation of onion solid waste (OSW) polyphenol extraction, using sodium propionate-based deep eutectic solvents (DESs) and process variables optimised through ... -
Effect of macronutrients and of anaerobic digestate on the heterotrophic cultivation of Chlorella vulgaris grown with glycerol
(2022)The aim of this work was to investigate the kinetics of the heterotrophic growth of Chlorella vulgaris as a means of producing bio-oil for biodiesel production. Glycerol was used as the sole organic carbon substrate. ... -
Excavated and dendritic Pt-Co nanocubes as efficient ethylene glycol and glycerol oxidation electrocatalysts
(2019)Noble metal electrocatalysts with excavated and dendritic architectures have recently attracted growing attention for their large accessible surface areas and high density of under-coordinated atoms. However, it is a tough ... -
Glycerol and glycerol-based deep eutectic mixtures as emerging green solvents for polyphenol extraction: The evidence so far
(2020)The acknowledgement that uncontrolled and excessive use of fossil resources has become a prime concern with regard to environmental deterioration, has shifted the orientation of economies towards the implementation of ... -
High-efficiency Extraction of Phenolics from Wheat Waste Biomass (Bran) by Combining Deep Eutectic Solvent, Ultrasound-assisted Pretreatment and Thermal Treatment
(2020)The aim of this study was the examination of the effect of ultrasonication pretreatment and thermal treatment of soft wheat bran (SWB) with a novel acidic, tertiary deep eutectic solvent, composed of glycerol/citric ... -
Hydrogenolysis of glycerol to propylene glycol by in situ produced hydrogen from aqueous phase reforming of glycerol over SiO2-Al2O3 supported nickel catalyst
(2016)In the present work, the reactions of glycerol's aqueous phase reforming (APR) and Aqueous Phase Hydrogenolysis (APH) in a batch reactor containing SiO2-Al2O3 supported 65% Ni catalyst are performed. The effect of: i) the ... -
Insights into intrauterine growth restriction based on maternal and umbilical cord blood metabolomics
(2021)Intrauterine growth restriction (IUGR) is a fetal adverse condition, ascribed by limited oxygen and nutrient supply from the mother to the fetus. Management of IUGR is an ongoing challenge because of its connection with ... -
Lipid production by Rhodosporidium toruloides from biodiesel-derived glycerol in shake flasks and bioreactor: Impact of initial C/N molar ratio and added onion-peel extract
(2022)Rhodosporidium toruloides NRRL Y-27012 grown in glycerol, produced yeast biomass and secondary metabolites as lipids (L) and intra-cellular polysaccharides (IPS) in trials under nitrogen limitation (initial C/N molar ratios ... -
Pulsed electric field: A “green” extraction technology for biomolecular products from glycerol with fermentation of non-Saccharomyces yeasts
(2022)Glycerol is the main organic by-product of the biodiesel industry and it can be a source of carbon for fermentations or a substrate for biotransformations. This work investigates a process that uses pulsed electric field ... -
A Thermodynamic approach of the aqueous-phase glucose reforming reaction for hydrogen production: A comparative study with glycerol and ethylene glycol
(2011)In the present work is reported for the first time the thermodynamic analysis of aqueous-phase glucose reforming. The reaction has been studied at low temperature values (298-338K) and at atmospheric pressure with the ...
