Retorting oil shale with iron oxide impregnated porous pellets

Patent ·
OSTI ID:5807144
Oil shale is mixed and retorted with hot porous pellets. The porous pellets have a surface area of at least 10 square meters per gram. Iron oxide is deposited or impregnated on the pellet surface area prior to retorting. The iron oxide imparts special properties to the pellets. After retorting, the pellets are separated from the processed oil shale solids, reheated and returned to a retort. At least a portion of the pellets are separated by a magnetic separator. 3 claims.
