摘要

Recovering gas and oil from oil shale comprises comminuting the oil shale, pre-drying or pre-heating, and heating indirectly to a reaction temperature required for the conversion of the contained kerogen. An independent claim is also included for an installation for recovering gas and oil from oil shale comprising a reactor (15) for the thermal treatment having a double wall and sluices for introducing and removing oil shale.
