The lab of chemist James Tour, a chair in chemistry as well as a professor of computer science and of materials science and nanoengineering at Rice University, 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 treated asphalt selects carbon dioxide over valuable methane at a ratio of more than 200-to-1.
