Experimental Determination of Ca-Silicate Dissolution Rates: A Source of Calcium for Geologic CO2 Sequestration

摘要

The international scientific community recognizes that greenhouse gases have the potential to influence climate, and that potential changes in sea level and weather patterns would be largely deleterious. Because carbon dioxide is emitted in such large quantities and its atmospheric concentration has been consistently rising throughout the recent past, it is only prudent to focus attention on reducing its emission and on developing strategies for its removal from the atmosphere. A variety of removal methods have been suggested ranging from deep-sea disposal, to recycling to methanol, and to conversion to solid carbonate. Problems appear to remain with all these strategies, and more work is needed to develop an acceptable, efficient method or set of methods.
