Carbon Dioxide Capture with Accelerated Carbonation of Industrial Combustion Waste

Abstract

One of the options of carbon dioxide capture and storage is the accelerated carbonation of industrial waste. The chemical process of carbonation of those materials and extraction characteristics were studied. Several target materials were screened based upon their physical and chemical characteristics for carbonation, amount of domestic production, and transportation distance between the waste production facility and carbon dioxide generation source. Selected candidate materials were coal combustion ash and municipal solid waste incinerator (MSWI) ash. Carbon dioxide capture potentials were estimated from the chemical compositions of alkaline materials such as CaO, MgO, Na 2 O, and K 2 O and acid neutralization capacities. From the carbon dioxide capture potentials and annual production of waste, the total amount of CO 2 removal by carbonation of industrial combustion waste in Korea could be estimated.

Synthesis of calcium carbonate powder from air-cooled blast furnace slag under pressurized CO2atmosphere

“…However, mineral carbonation has been limited in terms of its practical applicability, because natural calcium silicate resources are low and are thus expensive (Bertos et al, 2004). There have been considerable efforts to solve the problem using alternative calcium resources such as waste cement (You et al, 2011), combustion residue (Cho et al, 2011;Kojima et al, 1997) and steelmaking slag (Doucet et al, 2010;Eloneva, 2010;Teir et al, 2007;Teir, 2008). Among these, steelmaking slag is the most attractive alternative, as it is a readily available and inexpensive calcium-rich material andmost importantly -is created during the processes of iron and steel works, representing a large CO 2 resource and implying that it can be used not only for calcium carbonate production but also for on-site CO 2 sequestration.…”

The capture of carbon dioxide by transition metal aluminates, calcium aluminate, calcium zirconate, calcium silicate and lithium zirconate

“…A review describes the recent developments of the CO 2 adsorbents [18]. CaO, MgO, Na 2 O, and K 2 O have also been used to capture CO 2 [19]. Lithium zirconate (Li 2 ZrO 3 ) sorbents were tested for capturing CO 2 at high temperatures [20,21].…”

Carbon capture, utilization, and storage (CCUS) and how to accelerate the development and commercialization of carbon capture technologies and carbon-based products in the European and United States markets

“…The energy demand for mineralization is high mainly to overcome the slow reaction kinetics, as high reaction pressures and temperatures are recommended [220]. Factors that affect the kinetics of the carbonation reaction are exposure conditions, such as CO2 partial pressure, source and concentration, temperature, water/vapor content, porosity and permeability [221].…”

“…When HCFA is used as a complementary cementitious material it can augment some of the physical, behavioral, and structural properties of the concrete (e.g., compressive strength, workability, etc.) [221]. However, the possibility of using HCFA as concrete additive is not well established, especially in relation to the durability of concrete structures in aggressive environment [305].…”
