  • Oil Shale Processing an overview ScienceDirect Topics

    3/15/2011· The processing of shale oil is essentially done by retorting, which consists of heating crushed shale in a closed vessel up to a temperature (~ 500 °C) at which the matter releases crude oil, gases, char, and steam. The fraction of extractable oil is 10–20% by volume with respect to the solid shale

  • US4340463A System for utilizing oil shale fines Google

    A system is provided for utilizing fines of carbonaceous materials such as particles or pieces of oil shale of about one-half inch or less diameter which are rejected for use in some conventional or prior surface retorting process, which obtains maximum utilization of the energy content of the fines and which produces a waste which is relatively inert and of a size to facilitate disposal.
