Process for retorting oil shale mixtures with added carbonaceous material
Patent
·
OSTI ID:5941328
A process is claimed for retorting oil shale, especially lean oil shale, which comprises heating oil shale in a retort zone in the absence of substantial molecular oxygen to evolve hydrocarbonaceous vapors therefrom, thereby producing retorted shale; burning the retorted shale with added carbonaceous material in a combustion zone in the presence of an amount of added combustion catalyst sufficient to increase the rate of combustion of said added carbonaceous material in said combustion zone; and transferring heat from the combustion zone to heat said lean shale.
