High-Quality Syngas Production by Chemical Looping Gasification of Bituminite Based on NiFe₂O₄ Oxygen Carrier

Energies, 2023
Chemical looping gasification (CLG) is an effective coal utilization technology. In this work, the CLG of bituminite was investigated through fixed-bed batch experiments using NiFe2O4 oxygen carrier (OC) to achieve high-quality syngas. The changes in the

Sulfur Tolerance of CaxMn1–yMyO3−δ (M = Mg, Ti) Perovskite-Type Oxygen Carriers in Chemical-Looping with Oxygen Uncoupling (CLOU) [PDF]

, 2014
Perovskite-structured oxygen carriers of the type CaxMn1–yMyO3−δ (M = Mg, Ti) have been investigated for the CLOU process. The oxygen carrier particles were produced by spray-drying and were calcined at 1300 °C for 4 h.

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

International Journal of Greenhouse Gas Control, 2018
Abstract Chemical looping promises significant reductions in the cost of CO2 capture and storage (CCS) by enabling energy conversion with inherent separation of CO2 at almost no energy penalty. This study evaluates the economic performance of a novel power plant configuration based on the principle of packed bed chemical looping.

Mechanism study on the high-performance BaFe2O4 during chemical looping gasification

Fuel, 2022
Abstract As an attractive oxygen carrier, BaFe2O4 shows an outstanding chemical looping gasification (CLG) performance with a high CO yield, but the reaction mechanisms of BaFe2O4 during CLG process are still not clear. The present work aims to reveal the reaction mechanisms of BaFe2O4 with solid carbon (C) and carbon monoxide (CO) by means of ...
