The Fischer assay is a standardized laboratory test for determining the oil yield from oil shale to be expected from a conventional shale oil extraction . A 100 gram oil shale sample crushed to <2.38 mm is heated in a small aluminum retort to 500 °C (930 °F) at a rate of 12°C/min (22°F/min), and held at that temperature for 40 minutes. The distilled vapors of oil, gas, and water are passed through a condenser and cooled with ice water into a graduated centrifuge tube . The oil yields achieved by other technologies are often reported as a percentage of the Fischer Assay oil yield.
3-414: The original Fischer Assay test was developed in the early low temperature coal retorting research by Franz Joseph Emil Fischer and Hans Schrader. It was adapted for evaluating oil shale yields in 1949 by K. E. Stanfield and I. C. Frost. This article about energy , its collection, its distribution, or its uses is a stub .

Franz Joseph Emil Fischer Franz Joseph Emil Fischer (19 March 1877 in Freiburg im Breisgau – 1 December 1947 in Munich ) was a German chemist . He was the founder and first director of the Kaiser Wilhelm Institute for Coal Research . He is known for the discovery of the Fischer–Tropsch process . In 1925, he and Hans Tropsch discovered
9-534: The Fischer–Tropsch process . This allowed for the production of liquid hydrocarbons from carbon monoxide and hydrogen with metal catalyst at temperatures of 150–300 °C (302–572 °F). In 1930, he and Hans Schrader developed the Fischer assay , a standardized laboratory test for determining the oil yield from oil shale to be expected from a conventional shale oil extraction . He also worked with Wilhelm Ostwald and Hermann Emil Fischer . In 1913, he became
