Chemical-Looping Combustion and Gasification of Coals and Oxygen Carrier Development: A Brief Review
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 usi...
متن کاملResearch on the Gas Reburning in a Circulating Fluidized Bed (CFB) System Integrated with Biomass Gasification
N2O emissions from coal fired fluidized-bed combustion are approximately 30–360 mg/Nm, much higher than that from pulverized coal combustion (less than 30 mg/Nm). One approach to reduce the N2O is to reburn the biomass gasification gas in the coal-fired fluidized bed. In this paper, the effects of gasified biomass reburning on the integrated boiler system were investigated by both simulation an...
متن کاملDepth Three Towers of Rings and Groups
Depth three and finite depth are notions known for subfactors via diagrams and Frobenius extensions of rings via centralizers in endomorphism towers. From the point of view of depth two ring extensions, we provide a clear definition of depth three for a tower of three rings C ⊆ B ⊆ A. If A = EndBC and B |C is a Frobenius extension, this captures the notion of depth three for a Frobenius extensi...
متن کاملEffect of heat pretreatment/recarbonation in the Ca-looping
7 Even though an increasing number of pilot-scale plants are demonstrating the potential ef8 ficiency of the Ca-looping technology to capture CO2 at a commercial level, a still standing 9 matter of concern is the loss of carbonation reactivity of the regenerated CaO by calcination, 10 which is expected to be particularly marked at realistic conditions necessarily implying a high 11 CO2 partial ...
متن کاملEvaluation of CuO/MgAl2O4 in Biomass Chemical Looping Gasification with Oxygen Uncoupling
Chemical looping gasification (CLG) is a promising method for the utilization of biomass to produce syngas. However, its realization is largely dependent on the use of an oxygen carrier with a high and stable reactivity in cyclic reduction and oxidation. This work focused on the improvement of reactivity and stability of CuO in chemical looping gasification via the addition of MgAl2O4 as an ine...
