Chemical Looping with Oxygen Uncoupling of the Lignocellulosic Biomass Main Model Compound: Product Distribution and Kinetic Analysis on Lignin

Abstract: Product distribution and kinetic analysis of lignin were investigated during the chemical looping with oxygen uncoupling (CLOU) process. Thermodynamic simulation of the CLOU process was performed on the basis of the Gibbs free energy minimization method. The influence of the reaction temperature and mixing ratio of the oxygen carrier (CuO) on the product distribution was explored via a fixed-bed reactor combined with online mass spectrometry. Kinetic parameters from the formation of the main gas-phase products… Show more

“…Due to the very high reactivity of oxygen uncoupling materials, less metal oxide material used is needed in the system which could reduce the reactor size and associated costs. OU-BCLG is a new concept and a few studies related to OU-CLG have been performed with biomass [57][58][59].…”

“…Wang et al study the reaction performance of a CaSO 4 –Ca 2 CuO 3 mixed oxygen carrier with coal in CLC, which indicates that the addition of Ca 2 CuO 3 can substantially promote the reactivity of CaSO 4 toward the coal. Zhang et al investigate the product distribution as well as the reaction kinetics during the chemical looping with oxygen uncoupling (CLOU) of lignin by conducting fixed-bed reactor tests and thermodynamic simulation. Jiang et al report Cu and Ca co-doped lanthanum nickle perovskite-type materials (La 1– y Ca y Cu x Ni 1– x O 3 ) with facilitated O 2– transport capability as oxygen carriers for CLC of methane at low temperatures (200–600 °C).…”

“…Chemical looping with oxygen uncoupling (CLOU) is an innovative and improved idea with removal of the rate limiting stage of char gasification in CLC [6,7]. Many experimental studies have highlighted the feasibility of a twin fluidized bed for CLC as well as CLOU using coal, petcoke char particles and biomass as solid fuels [8][9][10][11][12].…”
