Preferred Abstract (Original):

Gas-phase brucite dehydroxylation and simultaneous dehydroxylation/carbonation processes were investigated to better understand the fundamental mechanisms involved and the role of different parameters governing them. Dehydroxylation was found to generally precede carbonation as a distinct but interrelated process. Above the minimum CO2 pressure for brucite carbonation, reactivity for both carbonation and dehydroxylationdecreases with increasing CO2 pressure. Low-temperature dehydroxylation prior to ...
