ABSTRACT:
In a process for the removal of fines from a bed of oil bearing shale in a travelling grate retort, a fluid such as air, inert gas or process gas is drafted through the bed in order to entrain in the fluid substantially all of the fines in the bed. The fines are then evacuated from the bed thus increasing the permeability of the bed and substantially decreasing the fines in the retorted shale oil.
