Crude shale oil from a Tosco II oil-shale retort and a NTU simulated in situ oil-shale retort were pyrolyzed with steam at atmospheric pressure in a bench-scale tubular reactor packed with ceramic balls. The reaction variables and their ranges studied were temperature from 1,348/sup 0/F to 1,637/sup 0/F, residence time from .3 sec. to 1.3 sec., and steam to hydrocarbon from .4 to 1.6. A constant temperature was maintained throughout the length of the reactor, maintaining constant reaction variables. The results were correlated with a pyrolysis severity factor which combined the effects of the 3 reaction variables. Increased severity of operation resulted in increases in conversion by weight to both solid and gaseous products, in total volumetric gaseous yields, in light saturates and light olefin yields, and in hydrogen yields.
