Waste CO2 edges toward feedstock role

摘要

LIKELY MOVES in the U.S. to limit greenhouse gas emissions (www.ChemicalProcessing.com/ articles/2008/038.html), coupled with significant efforts already taking place elsewhere are making the question of how to deal with recovered carbon dioxide all the more pressing. Simply storing the gas, such as in salt domes and depleted coal seams, is a widely cited option but one that poses long-term safety and other challenges. So, finding ways to productively use the CO2 clearly makes sense. Researchers at the University of Newcastle, Newcastle upon Tyne, U.K., believe they've identified a role for the gas as a feedstock.
