Asphalt-Derived Porous Carbon

Caption

Adding water to asphalt-derived porous carbon improves its ability to sequester carbon dioxide at natural gas wellheads, according to Rice University researchers. The porous particles in the illustration are combined with water and then heated to remove excess water from the pores. The water that remains binds to the pore structures. Under pressures above 20 atmospheres, the filter material sequesters carbon dioxide and allows methane molecules to pass through.
