Techno-economic analysis of chemical looping combustion with humid air turbine power cycle [PDF]
, 2014 Power generation from fossil fuel-fired power plant is the largest single source of CO₂ emission. CO₂ emission contributes to climate change. On the other hand, renewable energy is hindered by complex constraints in dealing with large scale application ...

Enhancement of char gasification in CO2 during chemical looping combustion
Chemical Engineering Journal, 2018 Three chars were gasified in CO2 in a fluidised bed of inert sand or Fe2O3 as an oxygen carrier (either derived from an ore or prepared in the laboratory). Rates of gasification were found to increase with temperature and the presence of active oxygen carriers. The observed change varied both with the chars’ and carriers’ reactivity.

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.

CCS from industrial sources [PDF]
, 2012 The literature concerning the application of CCS to industry is reviewed. Costs are presented for different sectors including ``high purity'' (processes which inherently produce a high concentration of CO2), cement, iron and steel, refinery and biomass ...
