“…Over the last decade, various types of OC have been reported, including pure 7,8 and supported metal oxides, [9][10][11][12] mixed metal oxides, 13,14 low cost materials, 15 and perovskites, [16][17][18] as summarized in a recent comprehensive review by Fan and coworkers. 19 Pure metal oxides such as NiO, 20 CuO, 21,22 24 have shown some problematic issues during repeated redox cycles, such as loss of stability because of the phase transformation (Mn 2 O 3 ), or agglomeration of particles due to the low melting point (CuO). To this end, these metal oxides have to be supported on the porous materials to improve the stability of the structure.…”

Fe‐substituted Ba‐hexaaluminates oxygen carrier for carbon dioxide capture by chemical looping combustion of methane

et al. 2015

in Wiley Online Library (wileyonlinelibrary.com) Fe-substituted Ba-hexaaluninates (BFA-x (x 5 1-3), x indicates Fe content) oxygen carrier (OC) were found to exhibit excellent sintering-resistance under cyclic redox atmosphere at 8008C thanks to the reservations of the structure during the CH 4 reduction step, thus preventing the agglomeration of particles during the subsequent reoxidation step. Lattice oxygen highly active for the total combustion of CH 4 was observed in the hexaaluminate structure and its chemical state was influenced by Fe content. The highest amount of active O coordinated with Fe 31 in the mirror plane (O-Fe 31 (M)) for the total combustion was reacted (0.77 mmol/g) for BaFe 3 Al 9 O 19 hexaaluminate OC. As a result, it exhibited the best reactivity with the CH 4 conversion of 83% and CO 2 selectivity of 100%. Moreover, superior regeneration and recyclability was also obtained, which originated from the fully recovery of O-Fe 31 (M) in the hexaaluminate structure.

“…Generally, a CLC system consists of two separate reaction zones, as shown in Fig.1. Metal (Me) particles are oxidized to metal oxide (MeO) particles in air in the oxidation zone, which is then transferred to the reduction zone where the fuel reduces them into CO 2 and H 2 O. There is no or little energy loss for the separation of CO 2 in the CLC process [5], because the relatively pure stream of CO 2 can be obtained after condensing and purifying H 2 O.…”

Abstract 3-D full loop CFD simulation of solids circulation rate is conducted in a complicated circulating-fluidized bed, which consists of a riser, a bubbling bed, a cyclone and a loop-seal. The effects of operating gas velocity, particle diameter and total solids inventory on the solids circulation rate are investigated based on the system pressure balance of an interconnected fluidized bed. CFD results indicate that the gas velocity in the riser plays a dominant role in controlling the solids circulation rate, whilst the gas velocity in the pot-seal influences in a narrow operating range. The solids circulation rate is strongly influenced by particle diameter and total solids inventory, but becomes insensitive to the operating conditions in the bubbling bed as the gas velocity is higher than the minimum fluidization velocity.

“…A summary is shown in Figure 7. For extensive reviews on this topic, including how this process can be modified for the purposes of coal gasification or hydrogen generation, see [45,46]. Calcium looping processes (CLP) take a different approach to CO2 capture in which CO2 is directly reacted with calcium oxide [47][48][49] or calcium hydroxide [50] to produce solid calcium carbonate, which can be separated easily from flue gas.…”

Comparison of CO2 Capture Approaches for Fossil-Based Power Generation: Review and Meta-Study

et al. 2017

View full text Add to dashboard Cite

This work is a meta-study of CO 2 capture processes for coal and natural gas power generation, including technologies such as post-combustion solvent-based carbon capture, the integrated gasification combined cycle process, oxyfuel combustion, membrane-based carbon capture processes, and solid oxide fuel cells. A literature survey of recent techno-economic studies was conducted, compiling relevant data on costs, efficiencies, and other performance metrics. The data were then converted in a consistent fashion to a common standard (such as a consistent net power output, country of construction, currency, base year of operation, and captured CO 2 pressure) such that a meaningful and direct comparison of technologies can be made. The processes were compared against a standard status quo power plant without carbon capture to compute metrics such as cost of CO 2 emissions avoided to identify the most promising designs and technologies to use for CO 2 emissions abatement.
