A process for obtaining carbon dioxide from furnace combustion fumes is provided. The process comprises removing water vapour occurring in combustion fumes through successive gas compression and expansion steps; separating carbon dioxide from oxygen and nitrogen through the use of a filter comprising a ...
of formation of sulfates in the atmosphere by oxygen isotope ratio measurements, a group of procedures was developed for the conversion of oxygen in sulfates, sulfur dioxide, air, and water to carbon dioxide for mass spectrometric determination of isotope ratios, using a single graphite furnace. A...
Dramatically increasing carbon dioxide concentrations are thought to cause a severe greenhouse effect, leading to severe and sustained global warming, associated climate instability and unwelcome natural disasters, melting glaciers and extreme weather patterns. The treatment of flue gas from thermal power ...
Process for the reaction of carbon monoxide with steam, with formation of carbon dioxide and hydrogen at elevated temperature in the presence of iron-containing catalysts (shift reaction), in which a catalyst is used, which contains finely divided iron oxide on an inert, thermostable carrier having...
Emissions reduction and greenhouse gas removal from the atmosphere are both necessary to achieve net-zero emissions and limit climate change1. There is thus a need for improved sorbents for the capture of carbon dioxide from the atmosphere, a process kno
Acidic gases such as sulphur dioxide (SO2) react with water in the atmosphere to form ‘acid rain’, a process known as acid deposition. When this rain falls, often a considerable distance from the original source of the gas, it causes ecosystem damage of varying degrees, depending upon the...
Carbon dioxide and steam are the activating agents commonly used. The removal of the outer and less ordered carbon atoms of the graphitic microcrystals leads to the creation of new micropores and/or the widening of their size in the char, what results in an increase of its pore volume. The...
Carbon Dioxide Emissions from Various Structural Frame Materials of Single-Family Houses in Nordic Countries. International Journal of Innovative Research and Scientific Studies, 2022, 5(2): 112-120. DOI:10.53894/ijirss.v5i2.414 70. Kanagaraj, B., Anand, N., Kiran, T. et al. EXPERIMENTAL ...
carbon dioxide when the composition in the flue gas is higher, there is a threshold at which the trend changes. This trend was observed both for different temperatures and type of steel slags (Yu and Wang2011). For example, for basic oxygen furnace slags, higher capture capacity was observed...
Although the LMDI decomposition model can quantify the contribution rate of each influencing factor in a specific year, it cannot examine the change in carbon dioxide caused by the change of a certain factor. The STIRPAT model compensates for the shortcomings of these models and can measure the ...
