Gilsonite asphalt derived porous carbon is activated carbon made from natural bitumen rather than coconut shell, wood or coal. Research at Rice University produced material with a surface area of 4,200 m²/g from a low-cost asphaltic feedstock using a two-step KOH activation — a figure at the upper end of what activated carbon achieves by […]
Gilsonite Natural Bitumen Gilsonite Natural bitumen in drilling, asphalt, ink, paint, and foundry Gilsonite is a naturally occurring, solid, black, lightweight organic material that originates from the solidification of petroleum. The dull, black appearance of weathered gilsonite resembles coal, whereas the surface of freshly broken gilsonite is shiny and resembles obsidian. Gilsonite Natural Bitumen is distinguished […]
