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 ...
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 ...
Characterization of combustion anomalies in a hydrogen-fueled 1.4 L commercial spark-ignition engine by means of in-cylinder pressure, block-engine vibration, and acoustic measurements
(Elsevier, 2018)
Artículo / Artikulua,
Abnormal combustion phenomena are among the main hurdles for the introduction of hydrogen in the transportation sector through the use of internal combustion engines (ICEs). For that reason the challenge is to guarantee ...
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 ...
Innovative catalyst integration on transparent silicone microreactors for photocatalytic applications
(Elsevier, 2022)
info:eu-repo/semantics/article,
Reproducible and controllable incorporation and immobilization of catalysts and other active particles onto silicone microreactor channels is still challenging. In this work, we present an innovative fabrication protocol ...
Exploring a low-cost valorization route for amazonian cocoa pod husks through thermochemical and catalytic upgrading of pyrolysis vapors
(ACS Publications, 2023)
Artículo / Artikulua,
Ecuador as an international leader in the production of cocoa beans produced more than 300 000 tons in 2021; hence, the management and valorization of the 2 MM tons of waste generated annually by this industry have a ...
Acoustic and psychoacoustic levels from an internal combustion engine fueled by hydrogen vs. gasoline
(Elsevier, 2022)
info:eu-repo/semantics/article,
Whereas noise generated by road traffic is an important factor in urban pollution, little attention has been paid to this issue in the field of hydrogen-fueled vehicles. The objective of this study is to analyze the influence ...
A techno-economic and life cycle assessment for the production of green methanol from CO2: catalyst and process bottlenecks
(Elsevier, 2022)
info:eu-repo/semantics/article,
The success of catalytic schemes for the large-scale valorization of CO2 does not only depend on the development of active, selective and stable catalytic materials but also on the overall process design. Here we present ...
UiO-66 MOF-Derived Ru@ZrO2 catalysts for photo-thermal CO2 hydrogenation
(MDPI, 2023)
Artículo / Artikulua,
The use of metal–organic frameworks (MOFs) as templates or precursors in the manufacture
of heterogeneous catalysts is highly attractive due to the transfer of MOFs’ inherent porosity and
homogeneous metallic distribution ...
Application of eco-design and life cycle assessment standards for environmental impact reduction of an industrial product
(MDPI, 2017)
info:eu-repo/semantics/article,
Eco-design is included within the framework of the standard for “Environmental management systems—Guidelines for incorporating Eco-design” (ISO 14006:2011). Eco-design process, as defined in standard, has six steps: (i) ...
