To improve CO2 filter for gas wells, just add water
December 12th, 2017To improve CO2 filter for gas wells, just add water
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. Tour is quoted. Almaz Jalilov, a former postdoctoral researcher at Rice and now an assistant professor at King Fahd University of Petroleum and Minerals in Saudi Arabia, is lead author of the study. Rice graduate student Yilun Li and research scientist Carter Kittrell are co-authors.
