Assessment of integration of methane-reduced ceria chemical looping CO2/H2O splitting cycle to an oxy-fired power plant
(2020-02-28)
Article
Open AccessIn this paper, we investigated the effect of reaction kinetics and moving bed reactors for chemical looping (CO2/H2O) splitting unit (CL) that produces syngas and fed back to the power plant to gain the efficiency loss due ... -
Simulation of two-step redox recycling of non-stoichiometric ceria with thermochemical dissociation of CO 2 /H 2 O in moving bed reactors – Part I: Model development with redox kinetics and sensitivity analysis
(2019-03-29)
Article
Open AccessChemical looping syngas production is a two-step process that produces CO and H2 from water and CO2 splitting. This is performed by exploiting a metal oxide as oxygen carrier material, which is thermally reduced and releases ... -
Simulation of two-step redox recycling of non-stoichiometric ceria with thermochemical dissociation of CO 2 /H 2 O in moving bed reactors – Part II: Techno-economic analysis and integration with 100¿MW oxyfuel power plant with carbon capture
(2019-09-21)
Article
Open AccessThis paper presents the model of a solar thermochemical looping CO2/H2O dissociation (CL) unit with commercial ceria as the redox oxygen carrier. The CL unit is integrated in an oxy-fuelled combined cycle power plant as ... -
Solar fuels via two-step thermochemical redox cycles for power and fuel production
(Universitat Politècnica de Catalunya, 2019-07-23)
Doctoral thesis
Open Access
Covenantee: Politecnico di TorinoWith the issue of the rise of anthropogenic CO2, global warming and rise of the primary energy demand, strong measures for the energy transition and the diversification with renewables and existing fossil-based infrastructure ... -
System efficiency analysis of dual interconnected bubbling fluidized bed reactors for solar fuel production
(Universidade do Minho, 2019-08-19)
Conference report
Open AccessChemical looping syngas production is a two-step syngas fuel production process that produces CO and H 2 . The process is composed of two fluidized bed reactors (oxidation reaction and reduction reactor), oxygen carriers ... -
Techno-economic and exergetic assessment of an oxy-fuel power plant fueled by syngas produced by chemical looping CO2 and H2O dissociation
(2018-10-01)
Article
Open AccessNatural Gas Combined Cycle (NGCC) is presently the most efficient fossil fuel power plant but with no carbon capture. The efficiency penalty resulting from the integration of carbon capture and storage (CCS) is, however, ... -
Techno-economic and exergy analysis of polygeneration plant for power and DME production with the integration of chemical looping CO 2 /H 2 O splitting
(Elsevier, 2019-04-15)
Article
Open AccessIn this paper, we present a novel polygeneration plant with carbon capture for the combined power and dimethyl ether (DME) production. The plant layout integrates a chemical looping CO2/H2O splitting (CL) unit producing ... -
Thermodynamic assessment of non-catalytic Ceria for syngas production by methane reduction and CO2 + H2O oxidation
(2019-03-01)
Article
Open AccessChemical looping syngas production is a two-step redox cycle with oxygen carriers (metal oxides) circulating between two interconnected reactors. In this paper, the performance of pure CeO2/Ce2O3 redox pair was investigated ...
