Title: Method for transforming fatty and oleaginous vegetable and animal matter into products similar to mineral oils
IPC: C10G3/00
Filed: 1937-01-04
Abstract: Fatty, oleaginous matter of vegetable or animal origin, such as earth nut oil, palm oil, lard, fish oil, &c., is transformed into products similar to mineral oils by distilling between 250 and 600 DEG  C. in the presence of alkali salts of weak acids or amphoteric oxides, such as alkali silicates, aluminates, carbonates, titanates, vanadates, uranates, zincates, plumbates and the like.  The products are blackishgreen fluorescent oils smelling of petroleum. Non-condensable gases formed may be returned to assist the distillation.  Catalysts may be recovered from the residues by carbonization, followed if necessary by treatment with steam.  In an alternative form of the process, hydrocarbon "wetting oils" are added to the fatty matter to assist the distillation in a preliminary stage.  Examples are given of (1) the distillation of old palm oil with potassium silicate; (2) the distillation of old palm oil with alumina and potassium carbonate; and (3) the distillation of karite kernels with light fuel oil and clay, the distillate then being treated according to (1) or (2).ALSO:Fatty, oleaginous matter of vegetable or animal origin, such as earth nut oil, palm oil, lard, fish oil, &c. is transformed into products similar to mineral oils by distilling between 250 and 600 DEG  C. in the presence of alkali salts of weak acids or amphoteric oxides, such as alkali silicates, aluminates, carbonates, titanates, vanadates, uranates, zincates, plumbates and the like.

Title: A new process for the refining of naphthas
Inventor: WADDINGTON WRIGHT
IPC: C10G17/06
Filed: 1955-01-11
Abstract: A process for refining tar naphthas combines a hydrogenation treatment with a dilute sulphuric acid wash in either order.  Tar naphthas are defined as those derived from coal tar, carburetted water gas tars, oil gas tars or from the gaseous products of coal carbonization, not more than 20% of which boil above 200 DEG  C.  The hydrogenation treatment utilizes pure hydrogen at pressures up to 200 lb./sq. inch, or gas mixtures containing hydrogen with a partial hydrogen pressure of up to 300 lb./sq. inch, and at a temperature in the range 330-450 DEG  C., over a catalyst.  Catalysts specified are compounds of cobalt and molybdenum and mixtures of cobalt and molybdenum in the metallic form or as oxides or sulphides.  The dilute sulphuric acid used is between 50 and 80% by weight strength, it may be used in amounts between 2 and 5% by volume, and it may be re-used several times.  In examples, crude naphtha was treated with hydrogen at 75 lb./sq. inch at 410 DEG  C. over cobalt molybdate and then washed with 65 % wt. sulphuric acid and vice versa.  In another example, coal gas at a pressure of 450 lb./sq. inch, corresponding to a partial pressure of hydrogen of 205 lb./sq. inch, was used in an otherwise similar treatment.
