“…CO 2 has a critical point at 31.06°C and 73.8 bars (1,070 lb/in 2 ) and a critical density of 0.469 g/cm 3 . It could be dissolved from the atmosphere in available water, and carbonic acid can be created with a pH around 5.6 (Haug et al, 2010). In addition, diffusion of CO 2 in water is approximately 10000 times lower than in air.…”

“…However, the kinetics of natural carbonation is extremely slow due to the relatively low CO 2 concentration, about 0.03-0.06% (Lackner, 2002;Costa et al, 2007). According to an investigation by Haug et al (2010), the weathering rate of olivine is estimated to be 10 −8.5 mol/(m 2 s) using the average ground temperature in Norway of 6°C and a pH of 5.6, which corresponds to the acidity of rainwater.…”

“…Various studies have addressed methods to speed up the kinetics of direct aqueous carbonation including physical and chemical pretreatment (Maroto-Valer et al, 2005a, b), electrolysis and heat pretreatment , and mechanical activation methods (McKelvy et al, 2004;Park and Fan, 2004;Haug et al, 2010;Haug et al, 2011). O'Connor et al (2002) investigated approaches to reduce particle size, and increase surface area, and elevate process temperature and pressure by thermal treatment or steam activation.…”

“…The majority of previous research has focused on the aqueous carbonation of naturally occurring silicate minerals such as serpentine (Mckelvy et al, 2004;Alexander et al, 2007;Krevor and Lackner, 2011), olivine (Haug et al, 2010), limestone (Symonds et al, 2009) and wollastonite (Tai et al, 2006;Huijgen et al, 2006c;Daval et al, 2009) due to their high calcium or magnesium content. Although the CO 2 storage capacity of these natural Ca-Mg-silicate minerals is sufficient to fix the CO 2 emitted from the combustion of fossil fuels, the technological carbonation of these minerals is slow and energy demanding.…”

CO 2 capture, utilization, and storage (CCUS) is a promising technology wherein CO 2 is captured and stored in solid form for further utilization instead of being released into the atmosphere in high concentrations. Under this framework, a new process called accelerated carbonation has been widely researched and developed. In this process, alkaline materials are reacted with high-purity CO 2 in the presence of moisture to accelerate the reaction to a timescale of a few minutes or hours. The feedstock for accelerated carbonation includes natural silicate-minerals (e.g., wollastonite, serpentine, and olivine) and industrial residues (e.g., steelmaking slag, municipal solid waste incinerator (MSWI) ash, and air pollution control (APC) residues). This research article focuses on carbonation technologies that use industrial alkaline wastes, such as steelmaking slags and metalworking wastewater. The carbonation of alkaline solid waste has been shown to be an effective way to capture CO 2 and to eliminate the contents of Ca(OH) 2 in solid residues, thus improving the durability of concrete blended with the carbonated residues. However, the operating conditions must be further studied for both the economic viability of the technology and the optimal conditions for CO 2 reaction.

Mineralization of Carbon Dioxide: A Literature Review

et al. 2015

View full text Add to dashboard Cite

Research on carbon capture and storage has been focused on CO 2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO 2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO 2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO 2 mineralization.

A method to enhance the CO₂ storage capacity of pyroxenitic rocks

et al. 2015

View full text Add to dashboard Cite

Investigation of new efficient pathways for CO2 sequestration is of great significance for the mitigation of climate change. Ultramafic rocks are considered among the most promising lithotypes for the safe storage of CO2 via mineral carbonation. This paper investigates a powerful method for the optimization of the ex situ carbonation of pyroxenitic rocks, which comprise part of ultramafic lithologies occurring in ophiolite complexes. The ball milling process was applied to a sample of pyroxenite from the Troodos ophiolite (Cyprus) for the first time, in order to create novel nanomaterials with enhanced CO2 storage capacity. The goal was to accelerate the kinetics of rock‐fluid reactions during the carbonation process. The starting rock material and the ball‐milled samples were characterized using a variety of methodologies. The experimental results imply that only a few hours of wet ball milling with ethanol as process control agent can substantially increase the CO2 storage capacity of pyroxenites. Through temperature‐programmed desorption of CO2 (CO2‐TPD) experiments, we show that the optimum milling conditions are 4 h of ball milling with 50 wt% ethanol, leading to an increase of the CO2 uptake of the studied rock material by 41 times. This notable increase designates that pyroxenites are very promising lithologies for CO2 storage via ex situ carbonation, and that ball milling can be an effective preparation technique for this process, providing an efficient and secure carbon storage solution.© 2015 Society of Chemical Industry and John Wiley & Sons, Ltd
