Scientific Significance

In this paper, Computational Fluid Dynamics (CFD) was used to simulate the magnetic device for the separation of Fe-base oxygen carrier in chemical-looping combustion system. The simulation was based on the Euler multiphase flow model and the k-ε turbulence model, which uses UDF programming to increase volume source phase. Here, commercial computational fluid dynamics software fluent platform was used to build the air reactor cold flow mathematical model, magnetic field under the conditions of different flow conditions were added for separating the Fe3O4 and Fe2O3. And the simulation results has an important understanding of the process of scientific significance, and will promote the fundamental understanding and applications of the Fe-base oxygen carrier.

Energy Penalty

Chemical-looping combustion is a promising method to realize the near zero emissions of CO2without any excessive energy penalty. In this paper the reactivity behavior of calcium sulfate (CaSO4) as oxygen carrier (OC) with coal chars are investigated. After the impregnation of nickel ions or iron ions, the reacting behaviors of the OC are remarkably promoted comparing with that before the impregnation. The high impregnation of nickel ions or iron ions is beneficial to the reactivity of the OC, especially in the first half of the reaction. After the reaction of fresh CaSO4with coal chars, the solid products are merely CaS. In addition, the solid products of Ni-impregnated OC consist mainly of CaS, CaO and Ni3S2while the solid products of Fe-impregnated OC are composed of Fe3O4and CaS.
