Evaluation of CuO/MgAl2O4 in Biomass Chemical Looping Gasification with Oxygen Uncoupling

BioResources, 2016
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.

Iron-based oxygen carriers in chemical looping conversions: A review

Carbon Resources Conversion, 2019
A solid oxygen carrier is usually applied in a chemical looping conversion process to transfer oxygen from the gaseous oxygen source to the fuel, which can avoid the direct contact of these two reactants and hence decrease the energy penalty of ...

Three-Dimensional Full Loop Modeling and Optimization of an in Situ Gasification Chemical Looping Combustion System [PDF]

Energy & Fuels, 2017
This study presents a comprehensive three-dimensional full loop simulation on a novel in situ gasification chemical looping combustion (iG-CLC) system. This iG-CLC model mainly consists of a high-flux circulating fluidized bed fuel reactor, a counter-flow moving bed air reactor, an inertial separator, a J-valve, and a downcomer.
