Title: Batch retort testing of the Cleveland and Sunbury seams of Kentucky oil shale
Abstract: Oil shale retorting technology utilizing a circular traveling grate (CTG) retort is discussed. In the process, a static bed of sized solids is transported through various retorting zones. Gas is drawn through the bed of solids at a constant pressure drop and delivers heat directly to the shale, effects interparticle transfer and finally recovers the remaining sensible heat prior to discharge of the spent shale from the retort. In addition to providing the means for heat transfer the gas acts as the transport medium for removing the products of retorting from the shale bed. The data for process design were obtained from retorting the shale in a cylindrical batch or pot retort. This device is essentially a black box simulation of a central core of shale taken from the CTG. During a test the desired retorting conditions are produced. The program performed in support of the Means Oil Shale Project is discussed. The specific shale studied was a representative blend of the Cleveland and Sunbury seams of the Devonian deposits. The parametric retorting studies conducted for process development are presented along with the comparison of shale sizing circuits and production of a bulk raw shale oil sample for hydrotreating testwork.
