Description
Verwertung von Sulfitablauge. Das Patent 412697 betrifft ein Verfahren zux'N%Iiederge-,vinnung des Schwefels aus Sulfitablauge, nach welchem die Ablauge unter verminderteni Druck abgeschwelt wird.Utilization of sulphite waste liquor. Patent 412697 relates to a method tox'N% recovery of sulfur from sulphite waste liquor, after which the waste liquor is sloughed off under reduced pressure.
Bei diesem Verfahren werden Nebeaprodukte gewonnen, die nicht direkt verwertbar sind.In this process, nebulous products are obtained that are not directly are usable.
Es hat sich nun herausgestellt, daß die Wiedergewinnung des Schwefels auch bei normalem sowie überdruck vorgenommen werden kann, wenn in einer Wasserstoffatmosphäre gearbeitet wird. An Stell-- von -Wasserstoff können auch wasserstoffhaltige Gase Verwendung -finden. Es werden dabei gleichzeitig außer Schwefel technisch verwertbare Nebenprodukte gewonnen, und zwar hauptsächlich Kohlenwasserstoffe aliphatischer Natur.It has now been found that the recovery of sulfur Can also be done at normal as well as overpressure when in a hydrogen atmosphere is being worked on. In place of hydrogen, hydrogen-containing gases can also be used Use-find. At the same time, apart from sulfur, there are also technically usable ones By-products obtained, mainly aliphatic hydrocarbons Nature.
Der Schwefel ist zum Teil als molekularer Schwefel, zum Teil als Schwefelwasserstoff und auch, in geringen Mengen als organische flüchtige Schwefelverbindungen vorhanden. Diese Verbindungen können nebeneinander durch eine Gasreinigungsmasse abgefangen werden.The sulfur is partly as molecular sulfur, partly as hydrogen sulfide and also, present in minor amounts as organic volatile sulfur compounds. These compounds can be intercepted next to one another by a gas cleaning compound will.
Die bei dem Verfahren, entstehenden aliphatis-chen Kohlenwasserstoffe stellen ein Gemenge von Kohlenwasserstoffen der allgemeinen Formel C" H", + 2 dar, deren Siedepunkt sehr weit auseinander liegt.The aliphatic hydrocarbons formed in the process represent a mixture of hydrocarbons of the general formula C "H", + 2, the boiling points of which are very far apart.
Als niedrigste Fraktion konnte normales Hexa:n nachgewiesen werden.Normal hexa: n could be detected as the lowest fraction.
Die Reaktionstemperatur kann innerhalb; ziemlich weiter Grenzeü -, und zwar von etwa 15o' bis etwa 45o' wechseln.The reaction temperature can be within; fairly wide limit -, from about 15o 'to about 45o'.
