titleOfInvention | Improvements in and relating to the manufacture of heating oils and internal combustion engine fuel oils |
abstract | Diesel and heating oils consisting of solutions of primary bitumen or of coal extract in an oil poor in hydrogen are rendered stable by adding an oil causing precipitation of the substances of high molecular weight which are at or near the solubility limit, removing the precipitate, as by filtration or centrifuging and then removing the precipitating oil, as by distillation. Precipitating oils specified are benzine, benzene, light oils produced by hydrogenating coal extracts or primary bitumens, and oil fractions of a paraffin base rich in hydrogen, e.g. those made in the Fischer-Tropsch CO-H2 synthesis. The precipitated substances may be further hydrogenated or may be used in the hydrogenating process for the manufacture of solvent oil from coal extract. In an example, a primary bitumen is obtained by treating coal with a deficiency of hydrogen in presence of a solvent; this bitumen is hydrogenated to obtain a light oil boiling below 220 DEG C. and a middle oil B.P. 200-400 DEG C. relatively poor in hydrogen. 35 lb. of the bitumen is dissolved in 65 lb. of the middle oil, and after heating to 80 DEG C. 20 lb. of a fraction boiling below 200 DEG C. of the light oil is mixed in; 8 lb. of oily matter is precipitated, stirred together, and filtered off; the light oil is then distilled off leaving a stabilized Diesel fuel oil. |
