AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A systematic framework is developed for the thermo-environomic modeling, analysis and optimization of fuel decarbonization processes using precombustion routes to decarbonize the fuel by CO2 removal before burning the purified H2-rich gas in a gas turbine ...
Within the goal of reducing the atmospheric CO2 emissions, CO2 capture and storage (CCS) is regarded as a promising option. For CO2 capture different concepts are investigated; post-combustion, pre-combustion and oxyfuel-combustion (pure O2 oxidation). Her ...
In the context of greenhouse gas emissions reduction, carbon capture and storage (CCS) is considered as a promising option, especially for power plants applications. Three different concepts are mainly investigated; pre-, oxy-fuel and post-combustion captu ...
This thesis is devoted to the study of activated processes at the nanoscale by means of state-of-the-art computer simulations. On the one hand, we are interested in addressing specific aspects of chemico-physical processes of great practical importance, na ...
Within the global challenge of climate change mitigation, CO2 capture and storage is regarded as a potential option to reduce the CO2 emissions in power plants. The most common technology to capture CO2 is chemical absorption with amines, requiring however ...
The photosensitized reduction of carbon dioxide by the molecular catalyst [Ru(bpy)2(CO)L] is studied in a biphasic liquid-condensed gas system. Increasing pressure is shown to enhance the initial production rate and turnover number of the catalyst before d ...
One of the main bottlenecks to deploying large-scale carbon dioxide capture and storage (CCS) in power plants is the energy required to separate the CO 2 from flue gas. For example, near-term CCS technology applied to coal-fired power plants is projected t ...
The reactivity of five di-n-butyltin(IV) complexes, n-Bu2Sn(OR)(2) (1), n-Bu2SnO (3), n-Bu2Sn(OR)O (4), (n-Bu2SnO)(2)(CO2) (6) and (n-Bu2SnO)(6)(n-Bu2SnOR)(2)(CO3) (7) (R = CH3), with CO2, suggested as possible catalyst precursors and key-interme ...
A review of the state of the art gas turbine power plants designs with CO2 capture was performed to set up a list of technologies to be considered in a conceptual process superstructure. It has been found that the efficiency and economics of carbon dioxide ...
