Abstract
A method of treating or remediating contaminated material, such as water or soil, comprises contacting such material with asphaltenes. The asphaltenes are preferably produced as a by-product of petroleum refining and, in particular, a by-product of vacuum residua. An adsorbent material comprising such asphaltenes is also provided.
Claims2
An adsorbent material for removing organic contaminants from contaminated material, wherein the adsorbent material comprises asphaltenes, and wherein the asphaltenes are petroleum asphaltenes separated from vacuum residua of a petroleum refining process and not subjected to further chemical modification, wherein:
- i) the asphaltenes are in the form of granules;
- or,
- ii) the asphaltenes are in the form of fibers and wherein the adsorbent material is in the form of a mat or a packing;
- and wherein the asphaltenes are immobilized by a retainer.
