Verfahren gar Verwertung vom Fisehabfällen. Process even recovery of fish waste.
Ea ist bereits bekamt» aus Hscnoelen und Fischtranen durch Hydrierung feste Fette heraus teilen« die sumr «eiteren Verarbeitung für Seifen etc. dienen. Demgegenüber besteht das vorliegende Verfahren aur Verwertung von Fisohabfallen darin, dase mm die Abfälle von Fischen aller Art einer trockenen Destillation unterwirft. Durch diese Destillation werden sämtliche nutsbaren Stoffe9 wie Fett, Xiweissbestandteile, Oele etc, aus den Fischabfällen entfernt und gehen in Daapfform über. Diese Daapfe werden sweckaässig bei gleicher Temperatur zusammen alt Wasserstoff über Katalysatoren geleitet, die vorzugsweise aus den Metallen der Gruppe 8 des periodischen Systems bestehen, insbesondere aus Hickel« lach Verlassen dieser ifydrtersehlaiige: werden die Dämpfe durch Kühler in den Vorlagen verdichtet· Ea is already known " to divide solid fats out of necks and fish oils by hydrogenation", which are used in more sumptuous processing for soaps, etc. In contrast, the present method is aur recovery of Fisohabfallen is dase mm, the waste of fish of all kinds of dry distillation is subjected. Through this distillation, all nutable substances 9 such as fat, Xiweiss constituents, oils etc. are removed from the fish waste and are converted into Daapfform. These steams are continuously passed together at the same temperature as hydrogen over catalysts, which preferably consist of the metals of group 8 of the periodic system, in particular from Hickel.
Bei diesem Verfahren entstehen folgende Produkte: 1.) Die in den übergehenden Dämpfen enthaltenen Oeidaapfe werden durch den Wasserstoff hydriert und als schmalz- oder Taselinarti^e Sabstansen im Kühler verdichtet. Diese Subetansen werden in an sich bekannter Weise su Fettsäuren verarbeitet.This process produces the following products: 1.) The egg bowls contained in the vapors passing over are hydrogenated by the hydrogen and compressed as lard or Taselinarti ^ e Sabstansen in the cooler. These subetanses are processed into fatty acids in a manner known per se.
2.) Bei der Yeraohwelung entweichen endlich die ungesättigten2.) With the Yeraohwelung finally the unsaturated ones escape

Unsaturated fatty acids are converted into saturated fatty acids by the hydrogenation, which, depending on the degree of hydrogenation, are converted into oils or aselike subetanses that swing on top of the visual water and can be easily skimmed off. ) obtained products m fatty acids Terarbeltet v
