Project Description: |
The goal
of this project is to develop an atomic level understanding of the mechanisms
that govern the kinetics of the complex Mg(OH)2
carbonation process to facilitate engineering of improved carbonation
materials and processes for carbon dioxide disposal. This project utilizes
environmental-cell (E-cell) dynamic high-resolution transmission electron
microscopy (DHRTEM) to probe the reaction processes down to and at the atomic
level. Other techniques are incorporated to optimally elucidate the overall
reaction process (e.g.; in-situ vs. ex-situ studies; advanced non-empirical
computer modeling and studies based on reactant particle and crystalline
grain size). As the overall carbonation process involves dehydroxylation;
carbonation and the potential competition between them; developing an
atomic-level understanding of the dehydroxylation
process is first targeted to provide a foundation from which to explore the
overall carbonation process. Process mechanisms are targeted for exploration
as a function of potential feedstock material characteristics; which may be
incorporated to enhance carbonation. In the first year the primary focus has
been on high purity Mg(OH)2 single crystal fragments
to elucidate basic reaction processes for highly crystalline material. In
years two and three we will also explore (i)
Mg(OH)2 materials containing crystalline defects to probe the effect of grain
boundaries; crystallinity; etc. on reaction processes and (ii) Mg(OH)2
materials containing known impurities to investigate the effects of
impurities (e.g.; Ca) on dehydroxylation/carbonation
processes. |
