Decarbonisation of steel mill gases in an energy-neutral chemical looping process Ghent University
The iron and steel industry is the largest industrial carbon dioxide emitter. More than 70% of their emissions originate from conventional combustion of steel mill gases. In this work, a strategy for carbon capture from the steel mill gases is laid out, using a combination of emerging technologies employing oxygen carrying nickel oxide, carbon dioxide accepting calcium oxide, and dioxygen uncoupling manganese(III) oxide. The process combination ...
Progress in in-situ CO2-sorption for enhanced hydrogen production Ghent University
Carbon Capture on a Micro Gas Turbine: Assessment of the Performance Vrije Universiteit Brussel
From all fossil fuel power production routes, the electricity produced with Gas Turbines (GTs) running on natural gas has the lowest CO2 emissions. However, if we want to move towards full carbon clean power production, the CO2 in the exhaust must be captured. The energy impact of a Carbon Capture plant (CC) applied to the micro Gas Turbine (mGT) still remains unclear because few quantitative analyses are available. The low concentration of CO2 ...
Microwave induced 'egg yolk' structure in Cr/V-MIL-53 Ghent University
Earth system models are not capturing present-day tropical forest carbon dynamics Ghent University
Tropical forests play a key role in absorbing carbon from the atmosphere into the land surface. Recent analyses of long-term (1985-2014) forest inventory plots across the tropics show that structurally intact tropical forest are a large carbon sink, but that this sink has saturated and is projected to be in long-term decline. Here we compare these results with estimates from the two latest generations of Earth System Models, Climate Modelling ...
High temperature H2S removal via CO2-assisted chemical looping over ZrO2-modified Fe2O3 Ghent University
Removal of H2S via hot gas desulfurization demands more advanced and efficient processes to meet the envi-ronmental and economic requirements of modern industry. Hereto, we propose a novel process, termed CO2- assisted Chemical Looping Hot Gas Desulfurization (CCLHGD), that involves alternating H2S-induced sulfuri-zation and CO2-enabled regeneration of a core-shell structured ZrO2-modified Fe2O3 oxygen carrier. Such CCLHGD process can be ...
CO2 sorption properties of Li4SiO4 with a Li2ZrO3 coating Ghent University
Intensifying blue hydrogen production by in situ CO2 utilisation Ghent University
Ionic Liquids for Carbon Dioxide Separation on Membranes KU Leuven
Reducing carbon dioxide (CO2) emissions is not only ecologists dream. Re-use of this gas can be beneficial for many industries where it is an important substrate. Since in the majority of the cases CO2 leaves the industrial site mixed with other gases, it has to be purified before it is captured. One promising method involves the use of membranes incorporating ionic liquids (ILs) that readily absorb CO2. Although several well-performing ILs have ...
