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 phase during chemical reaction and mechanism were explored. results show that elevated temperature adding a fraction steam facilitate reaction. Ad...

• Validation of optimum operating conditions for a Cu-based oxygen carrier. Very low air excess may be used in chemical looping combustion. Complete CH 4 conversion is achieved. Negligible copper loss due to migration the surface particles. Excellent mechanical performance Chemical combustion (CLC) allows fuel with inherent CO 2 capture by using an carrier transfer from fuel. Previously CLC sca...

Waste Activated Carbon (WAC), as a typical solid waste, can be utilized by Chemical-Looping Gasification (CLG) technology with an iron-based Oxygen Carrier (OC) to produce valuable synthesis gas. A series of experiments on WAC the CLG process has been performed in fixed-bed reactor. The operation parameters and cyclic performance OC have investigated during reactions. Fresh reaction samples ana...
