Abstract

Experiments were conducted in a dual-environment thermogravimetric reactor to investigate the interaction between calcination, sulfation, and carbonation for a limestone that had previously been shown to sulfate primarily in an unreacted core manner. The results indicate that carbon dioxide (CO{sub 2}) can reactivate partially sulfated sorbent particles, contributing to an increase in overall calcium utilization efficiency. The ability of sorbents to recapture CO{sub 2} decreases when cycles of calcination and carbonation are performed, following a pattern similar to sulfation/hydration cycling. 16 refs., 10 figs., 3 tabs.

Long-term calcination/carbonation cycling and thermal pretreatment for CO{sub 2} capture by limestone and dolomite

Journal Article Chen, Zhongxiang; Song, Hoon; Portillo, Miguel; ... - Energy and Fuels

Capturing carbon dioxide is vital for the future of climate-friendly combustion, gasification, and steam-re-forming processes. Dry processes utilizing simple sorbents have great potential in this regard. Long-term calcination/carbonation cycling was carried out in an atmospheric-pressure thermogravimetric reactor. Although dolomite gave better capture than limestone for a limited number of cycles, the advantage declined over many cycles. Under some circumstances, decreasing the carbonation temperature increased the rate of reaction because of the interaction between equilibrium and kinetic factors. Limestone and dolomite, after being pretreated thermally at high temperatures (1000 or 1100{sup o}C), showed a substantial increase in calcium utilization over manymore »« less

SO{sub 2} retention by reactivated CaO-based sorbent from multiple CO{sub 2} capture cycles

Journal Article Manovic, Vasilije; Anthony, Edward - Environmental Science and Technology

This paper examines the reactivation of spent sorbent, produced from multiple CO{sub 2} capture cycles, for use in SO{sub 2} capture. CaO-based sorbent samples were obtained from Kelly Rock limestone using three particle size ranges, each containing different impurities levels. Using a thermogravimetric analyzer (TGA), the sulfation behavior of partially sulfated and unsulfated samples obtained after multiple calcination-carbonation cycles in a tube furnace (TF), following steam reactivation in a pressurized reactor, is examined. In addition, samples calcined/sintered under different conditions after hydration are also examined. The results show that suitably treated spent sorbent has better sulfation characteristics than that ofmore »« less

CO{sub 2} capture capacity of CaO in long series of carbonation/calcination cycles

Journal Article Grasa, G; Abanades, J - Industrial and Engineering Chemistry Research

Calcium oxide can be an effective sorbent to separate CO{sub 2} at high temperatures. When coupled with a calcination step to produce pure CO{sub 2}, the carbonation reaction is the basis for several high-temperature CO{sub 2} capture systems. The evolution with cycling of the capture capacity of CaO derived from natural limestones is experimentally investigated in this work. Long series of carbonation/calcination cycles (up to 500) varying different variables affecting sorbent capacity have been tested in a thermogravimetric apparatus. Calcination temperatures above T > 950{sup o}C and very long calcination times accelerate the decay in sorption capacity, while other variablesmore »« less

SO{sub 2} Retention by CaO-Based Sorbent Spent in CO{sub 2} Looping Cycles

Journal Article Manovic, V; Anthony, E; Loncarevic, D - Industrial and Engineering Chemistry Research

CaO-based looping cycles are promising processes for CO{sub 2} Capture from both syngas and flue gas. The technology is based on cyclical carbonation of CaO and regeneration of CaCO{sub 3} in a dual fluidized-bed reactor to produce a pure CO{sub 2} stream suitable for sequestration. Use of spent sorbent from CO{sub 2} looping cycles for SO{sub 2} capture is investigated. Three limestones were investigated: Kelly Rock (Canada), La Blanca (Spain), and Katowice (Poland, Upper Silesia). Carbonation/calcination cycles were performed in a tube furnace with both the original limestones and samples thermally pretreated for different times (i.e., sintered). The spent sorbentmore »« less

Simultaneous CO{sub 2}/SO{sub 2} capture characteristics of three limestones in a fluidized-bed reactor

Journal Article Ryu, Ho-Jung; Grace, John; Lim, C - Energy and Fuels

Simultaneous CO{sub 2}/SO{sub 2} capture characteristics of three limestones were investigated in a pilot scale fluidized-bed reactor. For each of these sorbents, the measured CO{sub 2} capture capacity decreased as the number of cycles increased and as the SO{sub 2} concentration increased. On the other hand, the SO{sub 2} capture increased with the number of cycles and the SO{sub 2} concentration. The total calcium utilization decreased as the number of cycles increased, but the effect of SO{sub 2} concentration on the total calcium utilization depended on the sulfation pattern of limestone. For one limestone (with unreacted-core-type sulfation), the total calciummore »« less
