Results of a study of steam pyrolysis characteristics of a TOSCO II shale oil are reported. Up to 24 weight percent of the feed was converted to ethylene, and up to 6 weight percent was converted to propylene. The results are comparable with reported results and predictions for crude oil, gas oil, and shale oil. Within the ranges studied, an increase in any one of the reaction variables resulted in an increase of severity of operation. The effect of increasing the temperature was extreme, while increasing the residence time or steam-oil ratio had a much smaller effect. A modified form of a commonly used pyrolysis severity factor satisfactorily correlated the experimental results. Increasing the severity of operation resulted in increases in weight percent of feed converted to gaseous and solid products, in total volume of gaseous products, and in volumetric yields of methane and ethylene. The total light olefin yields increased sharply, then leveled off and began to decrease with increasing severity. The yields obtained from the TOSCO oil were greater in total gas and ethylene than crude shale oil from the gas combustion retort.
