Effects of Flow Improver Additives on Distillate Fuels from Oil Shale

The ability of additives to improve the cold flow properties of shale oil distillates boiling in the diesel fuel range was evaluated using hydrotreated shale oils as model fuels. Crude oil shale from Occidental Oil Shale Co. was fractionated to give three liquids in the diesel fuel boiling range. Each fraction was hydrotreated to three different severities to afford 9 different model fuels. A variety of commercial and experimental additives were evaluated as cold flow improvers in these fuels. Both the standard pour point test (ASTM D97) and a more severe low temperature flow test were employed. 7 refs.
