Patent ·
OSTI ID:6960249
The 380/sup 0/F + fraction of shale oil having a pour point of + 80/sup 0/F is visbroken at 825/sup 0/F and 1000 psig at a residence time of 10 minute. The vapor produced was separated and hydrotreated with an uptake of 50 std. ft H/barrel of shale oil. The combined product has a pour point of -45/sup 0/F as compared to -30/sup 0/F produced by visbreaking alone.
