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 ...

Investigations into the effects of volatile biomass tar on the performance of Fe-based CLC oxygen carrier materials

Environmental Research Letters, 2016
In this study we present findings from investigations into interactions between biomass tar and two iron based oxygen carrier materials (OCMs) designed for chemical-looping applications: a 100% Fe _2 O _3 (100Fe) OCM and a 60 wt% Fe _2 O _3 /40 wt% Al _2

Thermodynamic evaluation of a Ca-Cu looping post-combustion CO2 capture system integrated with thermochemical recuperation based on steam methane reforming

Case Studies in Thermal Engineering
The calcium looping integrated with the chemical looping combustion (CaL-CLC) process is an efficient and cost-effective CO2 capture technology that avoids the energy-intensive air separation unit in the calcium looping (CaL) process.

Reactivity improvement of ilmenite by calcium nitrate melt infiltration for Chemical Looping Combustion of biomass

Carbon Resources Conversion, 2019
Chemical Looping Combustion is a novel process that generates sequestration-ready CO2 from the combustion of woody biomass without requiring a gas separation step and without diluting the CO2 with N2 from air.

Integration of chemical looping oxygen production and chemical looping combustion in integrated gasification combined cycles

Fuel, 2018
Abstract Energy penalty is the primary economic challenge facing CO2 capture technology. This work aims to address this challenge through a novel power plant configuration, capable of achieving 45.4% electric efficiency from coal with a 95% CO2 capture efficiency.
