Life cycle assessment of power-to-methane systems with CO2 supplied by the chemical looping combustion of biomass
(Elsevier, 2022)
Artículo / Artikulua,
Power-to-methane (PtM) systems may allow fluctuations in the renewable energy supply to be smoothed out by storing surplus energy in the form of methane. These systems work by combining the hydrogen produced by electrolysis ...
Gaseous fueling of an adapted commercial automotive spark-ignition engine: simplified thermodynamic modeling and experimental study running on hydrogen, methane, carbon monoxide and their mixtures
(Elsevier, 2023)
Artículo / Artikulua,
In the present work, methane, carbon monoxide, hydrogen and the binary mixtures 20 % CH4–80 % H2, 80 %
CH4–20 % H2, 25 % CO–75 % H2 (by volume) were considered as fuels of a naturally aspirated port-fuel injection
four-cylinder ...
Application of a modeling tool to describe fly ash generation, composition, and melting behavior in a wheat straw fired commercial power plant
(MDPI, 2020)
info:eu-repo/semantics/article,
Ash behavior is a key operational aspect of industrial-scale power generation by means of biomass combustion. In this work, FactSage™ 6.4 software was used to develop and assess three models of wheat straw combustion in a ...
CO2 methanation over nickel catalysts: support effects investigated through specific activity and operando IR spectroscopy measurement
(MDPI, 2023)
Artículo / Artikulua,
Renewed interest in CO2 methanation is due to its role within the framework of the Power-to-Methane processes. While the use of nickel-based catalysts for CO2 methanation is well stablished, the support is being subjected ...
Extraction of phenolic compounds from populus salicaceae bark
(MDPI, 2022)
Artículo / Artikulua,
Lignocellulosic residues have the potential for obtaining high value-added products that could be better valorized if biorefinery strategies are adopted. The debarking of short-rotation crops yields important amounts of ...
Gold nanoparticles capped with a novel titanium(iv)-containing polyoxomolybdate cluster: selective and enhanced bactericidal effect against Escherichia coli
(Wiley, 2024)
Artículo / Artikulua,
Bacterial infections are a public health threat of increasing concern in medical care systems; hence, the search for novel strategies to lower the use of antibiotics and their harmful effects becomes imperative. Herein, ...
Environmental impact improvement of chitosan-based mixed-matrix membranes manufacture for CO2 gas separation by life cycle assessment
(Wiley, 2023)
Artículo / Artikulua,
The environmental impacts of the manufacture of chitosan (CS) and polymeric poly(1-trimethylsilyl-1-propyne) (PTMSP) mixed-matrix membranes (MMMs) for CO2 separation by life cycle assessment (LCA) are compared. An ionic ...
Innovative flow-through reaction system for the sustainable production of phenolic monomers from lignocellulose catalyzed by supported Mo2C
(Wiley, 2024)
Artículo / Artikulua,
Molybdenum carbide supported on activated carbon (β-Mo2C/AC) has been tested as catalyst in the reductive catalytic fractionation (RCF) of lignocellulosic biomass both in batch and in Flow-Through (FT) reaction systems. ...
Acid-catalyzed etherification of glycerol with tert-butanol: reaction monitoring through a complete identification of the produced alkyl ethers
(MDPI, 2023)
Artículo / Artikulua,
Higher tert-Butyl glycerol ethers (tBGEs) are interesting glycerol derivatives that can be produced from tert-butyl alcohol (TBA) and glycerol using an acid catalyst. Glycerol tert-butylation is a complex reaction that ...
Pseudo-homogeneous and heterogeneous kinetic models of the NaOH-catalyzed methanolysis reaction for biodiesel production
(MDPI, 2021)
info:eu-repo/semantics/article,
Methanolysis of vegetable oils in the presence of homogeneous catalysts remains the most important process for producing biodiesel. However, there is still a lack of accurate description of the reaction kinetics. This is ...
