Attrition resistance of calcium oxide–copper oxide–cement sorbents for post-combustion carbon dioxide capture.

Aug 18, 2012· Abstract. One of the post-combustion CO 2 capture technologies that have sufficiently been proved to be the best candidates for practical large scale post-combustion application is the calcium looping cycle. However, the CO 2 capture capacity of a calcium-based sorbent derived from natural limestone decays through long-term cyclic utilization; thus, the development of novel sorbents …

A number of oxidizing additives at different concentrations were used in the calcium-based sorbent production process. The Hg°, S02, and NOx capture capacities of these oxidant-enriched sorbents were evaluated and compared to those of a commercially available activated carbon in bench-scale, fixed-bed, and fluid-bed systems.

Carbon dioxide capture and storage can be a stop-gap measure to mitigate CO₂ emissions from existing fossil fuel facilities during their gradual replacement by low-carbon alternatives such as biomass. Calcium oxide-based CO₂ capture is a relatively mature technology, ready for implementation.

The calcium oxide looping cycle is considered to be one of the promising technologies for CO2 capture from fossil fuel power plants. How to improve CO2 capture and sintering-resistance performance of sorbents during the cycling is a challenge for researchers. An attempt was made to modify CaO sorbents by coal fly ash to improve the CO2 capture capacity and sintering resistance of sorbents, …

Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.

Calcium oxide (CaO) is a material that is being widely investigated in the context of CO 2 capture. One such application is as a CO 2 sorbent in the sorption-enhanced steam methane reforming processes (SERP). CO 2 is captured in an adsorption mode, where the conversion of CH 4 to H 2 is also enhanced, and released later in a separate desorption mode. This work presents an analysis of the ...
