Fate of NO and Ammonia in Chemical Looping Combustion─Investigation in a 300 W Chemical Looping Combustion Reactor System

چکیده
Chemical looping combustion (CLC) is a novel concept that transfers oxygen from air to fuel using an carrier circulates between reactor and reactor. Thus, the products, H2O CO2, are obtained in separate flow, ideally, pure CO2 gas stream after condensation of H2O. Consequently, CLC has unique potential for avoiding high costs energy penalties capture. Further, NO emissions can potentially be avoided. flameless, temperature too low formation thermal NOx. Moreover, NOx prompt do not form absence fuel. In reactor, prevents normal formation. However, when fuels containing nitrogen, may because oxidize nitrogen compounds. To achieve suited storage, must removed. Dependent upon how removed, process could free any emissions. reduction were investigated 300 W by adding either NH3 or NO. The work involved two different carriers, Linz–Donawitz (LD) slag ilmenite, temperatures, 850 900°C, circulation rates, flows syngas operation without with fully partially oxidized was studied. For LD slag, lower flow promoted decreased Likewise, higher temperatures raised lowered reduction. Ilmenite, however, far more superior respect only occurred carrier. reduced N2 all conditions, except ilmenite.

متن کاملDynamic Model of Single-reactor Chemical Looping Combustion
The paper presents a simplified model of chemical looping combustion in a fixed bed reactor under isothermal condition. Both reduction and regeneration phases of the oxygen carrier are modeled in the single reactor model under the hypothesis of discontinuous feed and simplified reaction kinetics. This model is meant to be the simplest possible formulation for a description that incorporates all...
متن کاملA Polygeneration System Based on Multi-Input Chemical Looping Combustion
This paper proposes a polygeneration system based on a multi-input chemical looping combustion system, which generates methanol and electricity, through the use of natural gas and coal. In this system, the chemical looping hydrogen (CLH) production system and the coal-based methanol production system are integrated. A high quality fuel, natural gas, is used to improve the conversion ratio of co...

Effect of gas composition in Chemical-Looping Combustion with copper based oxygen carriers: Fate of sulphur
Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can
