A previous intrabureau report has presented an evaluation of shale oil refining proposals in which visbroken shale oil was pipelined and the entire oil thermally cracked as the first processing step in California. The preliminary study presented in this report considers two other refining steps that could be applied to the visbroken oil at the pipeline terminal, 1) coking the crude oil and thermal cracking the coker gas oil and 2) coking the crude oil and high pressure hydrogenation of the coker distillate. The latter case is the Koppers refining process being applied in California. An earlier study evaluated the Koppers process on the basis of location in Colorado.
