McLendon, T R

Stacked oil shale bricks, with overall voids from 8 to 18%, were combustion retorted in a batch, pilot scale sized reactor. Experimental parameters were total void volume, oil shale grade, particle size, and retorting gas flow rate and composition. A hypothetical base case of experimental conditions was chosen to be in the region of commercial interest and the experimental parameters were varied one at a time from that base case. Oil yield was the dependent variable. Results indicate retorting of oil shale at very low voids is possible and efficient but pressure drops would be relatively high. Decreasing particle size, and interstitial velocity and adding steam increased oil yields. Oil yields varied from 70 to 83% of Fischer Assay. Cracking and combustion account for most of the oil losses. 51 references, 63 figures, 26 tables.
