    摘要: The removal of color bodies from an olefinic or saturated endo-endo hexacyclic homodimer of norbornadiene or mixtures thereof is accomplished by the use of a serpentine clay. Also acid bentonite clay or a montmorillonite clay can be used to remove the color bodies from the saturated dimer. The saturated dimer has a high density and a high heat of combustion making it useful as a missile fuel. Removal of the color bodies avoids possible catalyst poisoning in the hydrogenation of the olefinic to the saturated dimer. Also removal of the color bodies from the saturated dimer eliminates the possible problem of a material precipitating out on engine turbine blades and causing maintenance or operational problems.

    摘要: Oxygen compounds are removed, e.g., by solvent extraction, from a shale oil prior to its hydrogenation. As a result, the amount of hydrogen consumed during subsequent hydrogenation to achieve a given level of nitrogen for the shale oil is less than that which would occur if the oxygen compounds were not removed from the shale oil. Removal of the nitrogen is necessary to avoid adverse effects on subsequent shale oil processing steps such as catalytic cracking.
