Project Description

This project will develop a sensor for on-line analysis of the oxidation state of oxygen carrier particles such as iron oxides, copper oxides, and calcium sulfates and demonstrate its feasibility, set up and test a time-gated Raman spectroscopy system in combination with a pressurized high-temperature sample chamber, and optimize operating parameters of the Raman spectroscopy system and measure the high-temperature spectra of oxygen carriers, and develop an analysis procedure, including statistical modeling and multivariate calibration, for the interpretation of the Raman spectra.

Project Benefits

Ability to utilize an on-line optical sensor system that is capable of providing the oxidation state of oxygen carriers such as iron oxides, copper oxides, calcium sulfates, etc. Knowing the oxidation states of the oxygen carriers will provide in-situ information that can be used to make required adjustments for the optimization of future power generation technologies such as chemical looping.
