Pour point depressant for shale oil

Patent ·
OSTI ID:6038662
A process for producing a mixture of shale oils containing spherulites is described which comprises adding an effective amount of an about 1050/sup 0/F plus fraction of a raw shale oil containing spherulites, e.g., prepared by a solid-upflow fluid-downflow oil shale retorting process, to a waxy shale oil not containing spherulites, e.g., prepared by a solid-downflow fluid-upflow oil shale retorting process. The formation of spherulites in the mixture is accompanied by a lowered reduction in the pour point of the resulting shale oil mixture.
