Frontiers | Calcium Carbonate Precipitation for CO2 ...

The transformation of CO2 into a precipitated mineral carbonate through an ex situ mineral carbonation route is considered a promising option for carbon capture and storage (CCS) since (i) the captured CO2 can be stored permanently and (ii) industrial wastes (i.e., coal fly ash, steel and stainless-steel slags, and cement and lime kiln dusts) can be recycled and converted into value-added ...

Symmetry-breaking assembled porous calcite …

Abstract. Biomedical applications of porous calcium carbonate (CaCO 3) microspheres have been mainly restricted by their aqueous instability and low remineralization rate.To overcome these obstacles, a novel symmetry-breaking assembled porous calcite microsphere (PCMS) was constructed in an ethanol/water mixed system using a two-step vapor-diffusion/aging crystallization strategy.

03-01-2008· The use of high CO2 pressure may therefore be desirable for increasing the production rate of CaCO3, carbonation efficiency and purity, to approximately 48 kg/m3h, 95% and 96.3%, respectively in this study.

Evolution of Calcite Nanocrystals through Oriented ...

A nonclassical multistep pathway involving bottom-up and break-down stages for the evolution of calcite nanograins ∼50 nm in size was demonstrated in a basic aqueous system. Calcite nanofibrils ∼10 nm wide were produced as the initial crystalline phase via amorphous calcium carbonate through ion-by-ion assembly by the carbonation of Ca(OH)2 at a high pH of ∼13.

Rapid Carbonation for Calcite from a Solid-Liquid-Gas ...

Aqueous carbonation of Ca(OH) 2 is a complex process that produces calcite with scalenohedral calcite phases and characterized by inadequate carbonate species for effective carbonation due to the poor dissolution of CO 2 in water. Consequently, we report a solid-liquid-gas carbonation system with an ionic liquid (IL), 1-butyl-3-methylimidazolium bromide, in view of enhancing the reaction of CO ...

28-09-2010· The gas−solid carbonation of nanosized portlandite was experimentally investigated using a static bed reactor under anisobaric conditions. The effects of initial CO2 pressure (10−40 bar), reaction temperature (30 and 60 °C), and relative humidity were investigated. Three steps of the carbonation process were determined: (1) instantaneous CO2 mineralization during CO2 injection period.

This paper reviews the application of carbonation technology to the environmental industry as a way of reducing carbon dioxide (CO 2), a green house gas, including the presentation of related projects of our research group.An alternative technology to very slow natural carbonation is the co-called ‘accelerated carbonation’, which completes its fast reaction within few hours by using pure CO 2.
