Oil shale - Definition and More from the Free Merriam-Webster Dictionary:
Definition of OIL SHALE
: a rock (as shale) from which oil can be recovered by distillation
First Known Use of OIL SHALE
oil shalenoun (Concise Encyclopedia)
Any fine-grained sedimentary rock that contains solid organic matter (kerogen) and yields significant quantities of oil when heated. This shale oil is a potentially valuable fossil fuel, but the present methods of mining and refining it are expensive, damage the land, pollute the water, and produce carcinogenic wastes. Thus, oil shale will probably not be exploited on a wide scale until other petroleum resources have been nearly depleted. Estonia, China, and Brazil have facilities for producing relatively limited quantities, and the U.S. government operates an experimental plant in Colorado.
VKG - Total oil shale phenols:
Total oil shale phenolsPhenols and phenol products
Total phenols are produced by extraction from oil shale retort liquor. High reactive alkyl derivatives of resorcinol are the main components of total phenols. They are used as a chemical intermediate for synthetic tanning agents, various adhesive resins and plugging compositions for the repair and insulation of oil and gas wells.
