Results obtained from 17 experiments performed by the Bureau of Mines on Green River oil shales in a 10-ton batch retort are presented. The oil shales processed ranged in grade by Fischer assay from 20.4 to 48.0 gallons of oil per ton; air rates employed in retorting ranged to as high as 3.74 SCFM per square foot of bed. Multiple linear regression analysis was used to generate equations predicting the oil yield for given sets of retorting conditions. Using only controlled operating variables, an equation was developed that accounts for 83 percent of the variability in oil yield. Including ambient conditions in the regression improves the percentage to 93.
