SEM analysis on 40 percent iron oxide loading particle
SEM analysis on 40 percent iron oxide loading particle

Project Description

The goal of this project is to demonstrate the validity of a proposed novel strategy for synthesizing stronger and more chemically reactive particles for use in advanced fossil energy processes such as chemical looping combustion and post combustion capture of CO2. To accomplish this goal the project team will first synthesize and characterize Fe2O3-shell/Al2O3-core micro-particles using the technique of cyclic reduction/oxidation of the iron component of the particle. Then the project team will model the core-shell structure formation mechanism and determine by experiments, analytical measurements and modeling how to control the particle shell thickness. Comparisons of the morphology, mechanical strength, and reactivity of the core-shell structured particles will be compared with layered mixed oxides made by the conventional methods of vapor deposition and mechanical granulation. The project team will then demonstrate the applicability of the new core-shell synthesis strategy by preparing and testing a CaO-core/Fe2O3-shell particle for bulk CO2 adsorption use in advanced fossil energy processes.

Project Benefits

This project will develop novel low- cost environmentally friendly synthetic approaches toward core shell structured micro-particles for fossil energy applications. The approaches developed will benefit not only the chemical looping combustion/gasification and post-combustion CO2 capture as demonstrated in this study, but also many other related fossil energy conversion processes. Improvement to advanced combustion technology will promote the development of advanced power plant designs with improved efficiency and operational flexibility, resulting in lower capital and operating costs.
