Vacuum distillations of shale oil may be worthwhile since it produces a good steam pyrolysis feedstock. Maximum ethylene yield was 28.8% for the simulated in situ distillate and 22.6% for the Tosco II distillate. Yields are as good or better than those obtainable from conventional feedstocks. Severity of cracking is increased by increasing the residence time and temperature. The effect of steam to hydrocarbon ratio cannot be determined from the data. Trends observed with increasing severity were: (a) ethylene yield rises to a maximum, then slowly decreases; (b) propylene and butadiene yields continually decrease; (c) methane and hydrogen yields increase; (d) weight percent solids increased. Short residence times, in general, give the highest yields of valuable components. 2 tables, 4 figs.
