| On the basis of a cylindrical retort operated at Maoming a new design was developed for retorting oil shale using the concept of concentric circle jalousie thin layer retorting (CCJTLR). One of the Maoming production retorts was reconstructed and testing was made using both the whole recycle gas flow and the recycle gas mixed with gasification gas as heat carriers in the retorting process. The tests showed that the CCJTLR concept provided lower flow resistance and better gas flow distribution in the oil shale layer. Both versions led to increased shale oil yields from Maoming oil shale. The whole recycle heating flow gave better results compared to recycle-gasification flow. |
