A dab of water aids carbon capture
Rice scientists have found a way to make their asphalt-based sorbents better at capturing carbon dioxide from gas wells: Just add water. The lab of James Tour, the T.T. and W.F. Chao Professor of Chemistry, professor of computer science and of materials science and nanoengineering, discovered that treating grains of inexpensive Gilsonite asphalt with water allows the material to adsorb more than two times its weight in the greenhouse gas. The material performs well at ambient temperatures and under the pressures typically found at wellheads.
