Combustibles alternativos

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 1998
En este artículo se hace una revisión sobre los principales combustibles que se han propuesto últimamente para disminuír las emisiones de compuestos contaminantes a la atmósfera, produci­dos como consecuencia del uso de la gasolina común. En cada caso se consideran tanto los aspectos ambientales como económicos. Desde el punto de vista económico parece

Gd‐Induced Oxygen Vacancy Creation Activates Lattice Oxygen Oxidation for Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
DFT calculations shows that Gd incorporation into Fe‐doped NiO raises the O 2p band center, lowers oxygen vacancy formation energy, and thus promotes the LOM mechanism for OER. Gd and Fe co‐doped NiO nanosheets synthesized via spray combustion exhibits a low overpotential of 227 mV and maintains stable AEMWE performance for over 120 h, demonstrating ...

A novel method of pure oxy-fuel circulating fluidized bed combustion with zero recirculation flue gas : experimental validation

open access: yes, 2018
Applying oxy-fuel combustion requires more advanced combustion control methods to avoid inadmissible high flam temperature. In fluidized beds and pulverized unites, enhanced heat transfer and recirculation flue gas are used.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

open access: yesAdvanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

Cycle-to-Cycle Fluctuations of Burned Fuel Mass in Spark Ignition Combustion Engines [PDF]

open access: yesarXiv, 2003
We examine a simple, fuel-air, model of combustion in spark ignition (si) engine with indirect injection. In our two fluid model, variations of fuel mass burned in cycle sequences appear due to stochastic fluctuations of a fuel feed amount. We have shown that a small amplitude of these fluctuations affects considerably the stability of a combustion ...
