EHRENBERG, A, GEISLER, J Carbon dioxide emissions with cement production. In: Iron and steel slags - properties and utilization. Duisburg: 2000. Artigo apresentado no International Symposium on the Utilization of Metallurgical Salg - ISUS'99, 1999, Beijing, China....
Following power generation, cement stands as the second-largest industrial source of anthropogenic greenhouse gas emissions. However, in this invention a new molten salt chemistry now enables solar thermal energy to drive to calcium oxide production, completely eliminating carbon dioxide emissions during ...
The ZeroCAL approach, which can be integrated within the existing cement-production process, uses limestone feedstock to produce calcium hydroxide — which emits no carbon dioxide when burned to produce lime for cement. Byproducts of the process include hydrogen gas, which can be used as a clean...
Rapid production of high-strength cement-bonded particleboard using gaseous or supercritical carbon dioxide This study deals with the effects of curing treatment with gaseous and supercritical carbon dioxide on the properties of cement-bonded particleboard (CBP) ...

on the carbon cycle and biosphere is theextraction and burning offossil fuels, which directly transfer carbon from the geosphere into the atmosphere. Carbon dioxide is also produced and released during the calcination of limestone for clinker production. Clinker is an industrial precursor of cement. ...
carbon dioxide (co2) capture and storage technology in the cement and concrete industry - developments and innovation in carbon dioxide (co2) capture and storage technology: carbon dioxide (co2) captuelerated CO2 curing appear to be promising avenues for managing CO2 emissions by the cement and co...
Implications/Research Limitations : The study was limited to carbon dioxide emissions although it tried to look at other emissions in cement production. Other studies could focus on the actual impact on ecology. Practical Implications : Regulating the effects of cement production will contribute ...
Carbon capture and utilization for concrete production (CCU concrete) is estimated to sequester 0.1 to 1.4 gigatons of carbon dioxide (CO2) by 2050. However, existing estimates do not account for the CO2 impact from the capture, transport and utilization
Carbon dioxide (CO 2 ) is considered a trace gas in the atmosphere because it is much less abundant than oxygen or nitrogen. However, this trace gas plays a vital role in sustaining life on Earth and in controlling the Earth's climate by trapping heat in the atmosphere. ...
PURPOSE: A system is provided to be able to effectively process a supply stream of the unrefined carbon dioxide having a light polluted factor. CONSTITUTION: The production method of the carbon dioxide contains the steps of:passing the supplied material having a carbon dioxide and a light polluted...
