Investigation of surface properties of Avgamasya asphaltite

open access: yesFuel Processing Technology, 1994
Abstract Surface properties of Avgamasya asphaltite were investigated by the adsorption method using N 2 and CO 2 gases. In order to see the effect of ash content and pyrolysis temperature on the surface properties of asphaltite, samples were washed with 15% (v/v) HCl to reduce the ash content, and then pyrolyzed in a nitrogen atmosphere between ...
