High-temperature treatment of hydrous minerals

摘要

C:/NRPonbWlCC/KLLu 190462_.DOC-9/17/20[0 Increasing the activity of a hydrous magnesium silicate with respect to sequestration of carbon dioxide by mineral carbonation includes rapid heating of the hydrous magnesium silicate. Rapid heating of the hydrous magnesium silicate includes 5 heating a quantity of particles of hydrous magnesium silicate with flame conditions to substantially dehydroxylate the particles. The dehydroxylated particles can be contacted with carbon dioxide in a sequestration process to form magnesium carbonate.
