Description

Chemical looping combustion (CLC) technology has emerged as one of the most important clean combustion technologies, as it allows for sequestration of CO2 with minimal increase in energy requirements. The selection of the oxygen carrier material is essential to design an industrial CLC unit, and its choice impacts performance, durability, energy efficiency, and associated costs of the process. Natural oxygen carriers have garnered interest in recent decades due to their attractive pricing, but they suffer from low performance, as well as low mechanical and chemical stability. Synthetic oxygen carriers perform better and have usually a better stability but are more expensive, which can close the door to an economically viable process. This economic viability will depend mainly on the performance towards fuel conversion but also on the particle lifetime. This work aims at testing the performance of a synthetic oxygen carrier (OC) developed at IFPEN in a batch unit and in a 10 KWth continuous pilot with biomass and methane as fuel. Results show very promising performance towards fuel conversion and the lifetime of the OC has been estimated. However, a deactivation has been observed and consequently a parametric study has been performed in a batch unit to understand the probable cause of this deactivation and identify the most suitable operating conditions for long term operation. The study reveals that the temperature for reoxidation seems to play a crucial role for the chemical stability of the oxygen carrier while reoxidation duration or reduction degree are less impactful.
