- Fischer Assay
Fischer Assay is a standardized laboratory test for determining the oil yield from
oil shale to be expected from a conventionaloil shale extraction . A 100 gram oil shale sample crushed to <2.38 mm is heated in a small aluminumretort to convert|500|°C|°F|-1 at a rate of convert|12|°C|°F|0 per minute, and held at that temperature for 40 minutes.Cite paper

accessdate=2008-08-18] The distilled vapors of oil, gas, and water are passed through a condenser and cooled with ice water into a graduatedcentrifuge tube . The oil yields achieved by other technologies are often reported as a percentage of the Fischer Assay oil yield.The original Fischer Assay test was developed in the early low temperature coal retorting research by
Franz Joseph Emil Fischer and Hans Schrader.Cite paper
