“…to determine the effectiveness of reducing the migration of spilled crude petroleum through soil horizons by applying finely-divided activated sub-bituminous coal as a sorbent / agglomerating agent. Although other sorbents are commonly in use, the oleophilic nature of coal and experience to date with coal-oil agglomeration (Capes, 1991;Arnold, 1993;Hower et. al., 1997) suggest that finely divided coal might be an effective binder for crude oil.…”

Abstract. Investigation to determine the feasibility of containment of spilled petroleum in soil or near surface mineral matter, using finely-divided, heatactivated sub-bituminous coal as a sorbent and binder, has begun. Cylindrical samples (75mm diameter x 150 mm height) prepared separately from organic-rich soil and an underlying silt-clay horizon, both typical of substrates in the central Alaskan zone of the Trans-Alaska petroleum pipeline, were studied, along with a well-sorted sand (used in concrete-making) as a reference material. Downward permeation of run-of-pipeline crude petroleum through the organic soil, clay-rich subsoil, and sand, at one hour, eight hour, and 24 hour intervals, with and without a 30-minute delayed topical application of fine coal, is determined. Direct adsorption of the crude petroleum and formation of coal-oil agglomerates occurs when supernatant oil remains on the sample surface (as in the case of the clay-rich substrate). Wicking and partial adsorption occurs if the crude petroleum has migrated below the sample surface. Separation of the coal-oil agglomerate may be possible by simple mechanical means -or if necessary, by froth flotation -to yield a value-added fuel which can be briquetted for ease of handling. Phase One of this study, reported here, addresses phenomena at ambient indoor temperature. Phase Two will address similar phenomena under frozen conditions, typical of Alaskan continuous and discontinuous permafrost zones. Phase Three will address the absorption of oil remaining in the substrate long after an oil spill or leak has occurred. Additional
