Oil shale retorting process. [reduction of arsenic content in shale oil]
Patent
·
OSTI ID:6567092
The concentration of arsenic in shale oil produced from retorting arsenic-containing oil shale in a conventional retorting kiln is reduced by blending with said oil shale a nickel-containing additive. During retorting, the amount of arsenic released in vaporous form from the oil shale is reduced, thereby decreasing the amount of arsenic which collects with the produced liquid shale oil. Thus, a shale oil is produced having a significantly lower arsenic content than is obtainable without the use of the nickel additive.
