Kinetic analysis of a Cu-based oxygen carrier: Relevance of temperature and oxygen partial pressure on reduction and oxidation reactions rates in Chemical Looping with Oxygen Uncoupling (CLOU)

Characterization of a Sol-gel Derived CuO/CuAl2O4 Oxygen Carrier for Chemical Looping Combustion (CLC) and Chemical Looping with Oxygen Uncoupling (CLOU) of Gaseous Fuels

Characterization of natural copper ore in anthracite fueled Chemical-Looping with Oxygen Uncoupling (CLOU)

Chemical Looping with Oxygen Uncoupling (CLOU) is an advanced approach proposed for improving the utilization degree of solid fuels and speeding up the reaction rate in Chemical-Looping Combustion technology (CLC). In CLOU system, OC circulates between fuel reactor (FR) and air reactor (AR), providing gaseous oxygen for the combustion of fuels (in FR) and then being regenerated by absorbing gas...

Temperature variations in the oxygen carrier particles during their reduction and oxidation in a chemical-looping combustion system

A particle reaction model including mass and heat transfer has been developed to know the temperature variations produced inside the oxygen carrier particles during the cyclic reduction and oxidation reactions taking place in a Chemical-Looping Combustion (CLC) system. The reactions of the different oxygen carriers based on Cu, Co, Fe, Mn, and Ni during the reduction with fuel gas (CH4, CO, and...

Effect of Dissolved Oxygen and Chemical Oxygen Demand to Nitrogen Ratios on the Partial Nitrification/Denitrification Process in Moving bed Biofilm Reactors

Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewaterwith high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO)and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal fromsynthetic wastewater was investigated. Experiments were c...
