“…In the iron-based process, the syngas is converted into CO2 and H2O and the iron oxide (Fe2O3) is reduced to a mixture of Fe and FeO at 750-900 °C and 30 atm in the fuel reactor (Reactions 15-18). In the hydrogen reactor, the reduced oxide reacts with steam to generate H2 at 500-750 °C and 30 atm (Reaction [19][20]. The Fe3O4 generated from the hydrogen reactor is regenerated to Fe2O3 through air combustion (Reaction 21).…”

“…The fuel particles have lower density and smaller size at this stage. Oxygen-carriers have been tested in chemical-looping combustion and gasification processes for solid fuels (coal, petroleum coke, biomass) [9,13,16,[18][19][20]. From Table 2, bituminous coal is commonly used in the pilot scale tests due to its high reactivity.…”

“…Chemical-looping combustion with gaseous fuels has been mainly studied and developed in recent years and was reviewed by Adanez et al [3] and Hossain and de Lasa [8]. More recently, CLC research has focused on solid fuels because of rich solid fuel resources [9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Figure 1.…”

Chemical-looping technology is one of the promising CO2 capture technologies. It generates a CO2 enriched flue gas, which will greatly benefit CO2 capture, utilization or sequestration. Both chemical-looping combustion (CLC) and chemical-looping gasification (CLG) have the potential to be used to generate power, chemicals, and liquid fuels. Chemical-looping is an oxygen transporting process using oxygen carriers. Recently, attention has focused on solid fuels such as coal. Coal chemical-looping reactions are more complicated than gaseous fuels due to coal properties (like mineral matter) and the complex reaction pathways involving solid fuels. The mineral matter/ash and sulfur in coal may affect the activity of oxygen carriers. Oxygen carriers are the key issue in chemical-looping processes. Thermogravimetric analysis (TGA) has been widely used for the development of oxygen carriers (e.g., oxide reactivity). Two proposed processes for the CLC of solid fuels are in-situ Gasification Chemical-Looping Combustion (iG-CLC) and Chemical-Looping with Oxygen Uncoupling (CLOU). The objectives of this review are to discuss various chemical-looping processes with coal, summarize TGA applications in oxygen carrier development, and outline the major challenges associated with coal chemical-looping in iG-CLC and CLOU.

“…During past years, extensive studies of CLC of gaseous fuels with iron oxide as OC have been conducted [11,12], and the CLC reaction mechanisms and CLC equipment are relatively clear. In recent years, CLC with solid fuels have received great interests for the rich solid fuel resources [13][14][15][16][17][18], and the feasibility has been confirmed by many experiments. Biomass direct combustion is thought In a CLC system, an oxygen carrier is critical to obtain an excellent CLC performance for its vital functions of transferring oxygen and heat.…”

Biomass direct combustion is thought to be a near zero emission of CO 2 model since the CO 2 released in combustion had previously been removed from the atmosphere during biomass growth.…”

Lignocellulose is considered an efficient raw material to produce fuel ethanol. Clean utilization of the solid residue derived from lignocellulose‐based fuel ethanol is important for the biomass‐to‐ethanol production chain. Combustion characteristics of the residue originating from corn stalk‐based cellulosic ethanol are studied in a circulating fluidized bed. Results indicate that circulating fluidized‐bed combustion is an effective and stable way to burn the residue with high moisture content. CO emission during biomass combustion in a circulating fluidized bed is low in the range of several ppm. NO and N2O are the major pollutants during residue combustion. The optimal combustion temperature is limited to avoid agglomeration and reduce pollutant emission. Design data and theoretical support for design and operation of the residue combustion circulating fluidized‐bed boiler are provided.
