Title: Process and apparatus for converting hydrocarbon into fatty acids
Filed: 1920-07-10
Abstract: 148,892. Deutsche Erd÷l Akt.-Ges. July 12, 1919, [Convention date]. Fatty acids are manufactured by treating aliphatic hydrocarbons in the form of a fine spray with oxygen, air or ozone. A catalyst may or may not be present. As starting-materials are mentioned, petroleum or its distillates, tars from the distillation of wood. peat, shale, lignite, or coal, and products from such tars. An apparatus is described comprising a vertical chamber A into the top of which the liquid hydrocarbon, drawn by the pump E from the reservoir D, is sprayed through a nozzle or injector F1. The chamber A may be heated and may contain inert material supporting a catalyst. The oxidized hydrocarbons flow from the chamber into receivers G1 and G2 and hence back to reservoir D. The gases pass out of the reaction chamber by the pipes J1, J2 and through the condensers B, U and the scrubber M to remove volatile oxidation products. The gases are returned to the reaction chamber via the gasholder N and the pump P, being enriched by addition of oxygen from the cylinder Q. The process is continued (for 10-12 hours) until a sample taken indicates that the oxidation has proceeded sufficiently far. Specification 21941/05 is referred to.
