Description

Verfahren zur Herstellung von Schwefel-Kohlenstoff und organischen Schwefelverbindungen Das Patent 803 i 14 betrifft ein Verfahren zur Herstellung vorn S,chwefel-Kohlenstoff, wobei man Gasgemische, welche heträchtliche Mengen Methan und außerdem Schwefehvasserstoff oder schwefelwasserstoffbild:ende Stoffe enthalten, Temperaturen von oberhalb 100o° aussetzt. Im Patent 848 646 wird Idas. Methan ganz oder teilweise durch dessen gas-oder dampfförmige Homologe, gas- oder dampfförmige Olefine oder Acetylenersetzt und bei Temperaturen von etwa 60o bis iooo° gearbeitet. Hierbei entstehen auch andere organische Schwefelverbindungen ,als Schwefel-Ko-hlenstoff. Diese entstehen, besonders dann, wenn man mit @erheblichem Schwefelwasserstoffüberschuß arbeitet. Es wurde nun gefunden, daß, man nach der vorstehend geschilderten Erfindung ebenfalls Schwefel-Kohlenstoff und ,andere. organische Schwefelverbindungen erhält, wenn man an Stelle der angeführten gas- und dampfförmigen. Kohlenwasserstoffe flüssige, nicht völlig verdampfhare Gemische verwendet, die Kohlenwasserstoffe enthalten oder aus solchen bestehen, wie z. B. Teere, Ölrückstände, Asphalte und sonstige Bitumina. Auch hierbei arbeitet man bei. Temperaturen, wie sie im Haupt-und ersten Zusatzpatent vorgesehen sind, nämlich hei .etwa 60o bis 130o° und darüber. Bei Temperaturen zwischen 60o und goo° entstehen dabei vorwiegend organische Schwefelverbindungen, wie M°rkaptane, Thioäther, organische -Di:ä'uldle, -T`hiöphen und Thiophenhomolloge; bei Temperaturen oberhalb 9oo°, insbesondere oberhalb iooo°, bildet sich hin- gegen vorwiegend Schwiefel-Kohlenstoff. 'Als Aus- gangsstoffe dienen z. B. Erdöldestillätionsrück- stände, Braunkohlen- und Steinkohlenbeere oder deren Rückstände, Asphalte lod, dgl., insbesondeie auch Kohlenstoff und Wasserstoff @enthaltende Rück- stände der organischen chemischen Industrie, z. B. der Kohlehydrierung, des Fischer-Tropsch-Verfah- rens, der Paraffinoxydation, ferner Schmierölab- fällie u. dgl. Das Verfahren kann in von außen beheizten Rohren oder Kammern Moder besser noch.in. p:eri- ,odiscb ,aufheizbanen Kammern mit wärmespeichern- der, gegebenenfalls katalytisch wirkender Füllung, durchgeführt werden, wobei im letzteren-Fall die Füllung, sio,fem sie in körniger Form. vorliegt, durch idie Reiaktiomsgase und -dämpfe, in ihrer ganzen Schichthöhle in wirbelnder Bewegung, deiner kochenden Flüssigkeit, gehalten werden barm. Die nicht völlig verdamplbaren. Ausgangs,- stofe werden zweckmäßig mittels Düsen in fein- verteiltem Zustand in Iden Reaktionsraum ein- geführt. Die nicht umgesetzten Kohlenwasserstoffe .und die gebildeten, vorwiegend gasförmigen Kohlen- wassersboffiewerden nach Entfernung der gebildeten Schwefelverbindungen dem Verfahren wieder zu- geführt: Beispiel In seinem Gasterzeuger von ö,5 m Innendürch= mes.ser, der mit einer glühenden Koksschicht ge-, füllt ist (Höhe der Schicht etwa i m, Körnung i bis q. mm), Temperatur 85o', führt man vorn unten Schwefelwasserstoff :ein in .einer Menge von i 2o ,cbm/h. Dadurch -wird der glühende Koks in kochende Bewegung versetzt. Gleichzeitig spritzt man in den unteren Teil der bewegten glühenden Koksschicht mittels Düse Erdöldestillatiänsrück- stände leim. (Siedebeginn loberhalb 3oo°) in lein:er Menge von q. kg während g Minuten. Aus T ',den ents@tehenderi- Gasen und . Dämpfen werden, idurch Kühlung je Kubikmeter rund Zoo. g Öl gewonnen, welches von q.o bis 25o° siedet und neben kleinen Mengen flüssigen Kohlenwasser-Stoffen große Mengen -1organischer Schwefelverbindungen, wie Merkaptane, Disulfide, Thioäther, Thiophen, ferner Schwefel-Kohlenstoff enthält. Die Abgase lenthalten neben Wasserstoff noch Methankohlenwas,serstoffe und ,gasförmige Olefine sowie nicht umgesetzten Schwefelwasserstoff. Letzterer kann zusummen mit den Methankohlenwasserstoffen und -den Olefinen wieder zurückgeführt werden.A process for the preparation of sulfur-carbon and organic sulfur compounds, the patent 803 i 14 relates to a method for producing the front S, chwefel-carbon to give, gas mixtures which heträchtliche amounts of methane and also Schwefehvasserstoff or hydrogen sulfide-picture: contain substances, temperatures above 100o ° suspends. In the patent 848,646 Idas. Methane is completely or partially replaced by its gaseous or vaporous homologues, gaseous or vaporous olefins or acetylene, and the process is carried out at temperatures of about 60 ° to 100 °. This also creates other organic sulfur compounds than sulfur-carbon. These arise, especially when working with a considerable excess of hydrogen sulfide. It has now been found that, according to the invention described above, sulfur-carbon and others. Organic sulfur compounds are obtained if the gaseous and vaporous ones are used instead. Hydrocarbons liquid, not completely evaporative mixtures used, which contain hydrocarbons or consist of such, such. B. Tars, oil residues, asphalt and other bitumens. Here, too, one works at. Temperatures as provided in the main patent and the first additional patent, namely about 60o to 130o ° and above. At temperatures between 60o and goo °, mainly organic sulfur compounds such as m ° rcaptans, Thioether, organic -Di: ä'uldle, -T`hiöphen and Thiophen homologue; at temperatures above 900 °, especially above 100 °, forms against predominantly Schwiefel carbon. 'As an raw materials serve z. B. Petroleum distillation return stands, lignite and coal berries or their residues, asphalt iodine, the like, in particular also carbon and hydrogen @containing return stands of the organic chemical industry, z. B. carbohydrate hydrogenation, the Fischer-Tropsch process rens, the paraffin oxidation, furthermore lubricating oil fall and the like The process can be carried out in externally heated Pipes or chambers Moder better still.in. p: eri- , odiscb, heated chambers with heat storage the filling, which may have a catalytic effect, be carried out, in the latter case the Filling, sio, fem them in granular form. is present, through the reaction gases and vapors, in their whole layer cavity in whirling motion, your boiling liquid barely. The ones that cannot be completely fooled. Starting - substances are expediently fine-tuned using nozzles distributed state in the reaction space guided. The unreacted hydrocarbons and the predominantly gaseous carbon Wasserboffiewerden after removal of the formed Sulfur compounds back into the process. guided: example In his guest producer of Ö.5 m inner door = mes.ser, which is covered with a glowing layer of coke, is filled (height of the layer about im, grain size i to q. mm), temperature 85o ', one leads in front below hydrogen sulfide: one in .a lot of i 2o, cbm / h. This causes the glowing coke to move in boiling movement. Splashes at the same time one in the lower part of the moving glowing Layer of coke by means of nozzle oil distillation return stands glue. (Boiling begins above 300 °) in linen: he Set of q. kg for g minutes. From T ', the corresponding gases and. Steaming will be done by cooling per cubic meter around zoo. g of oil obtained, which boils from qo to 25o ° and, in addition to small amounts of liquid hydrocarbons, contains large amounts of organic sulfur compounds such as mercaptans, disulphides, thioethers, thiophene, and also sulfur carbon. In addition to hydrogen, the exhaust gases also contain methane hydrocarbons, hydrogen and gaseous olefins and unconverted hydrogen sulfide. The latter can be recycled together with the methane hydrocarbons and methane olefins.

Nach einer Reaktionsperiode von 5 Minuten wird die Koksfüllung mit Luft wiederheiß geblasen und für die nächste Reaktionsperiode vorbereitet.After a reaction period of 5 minutes, the coke filling becomes with Air blown again and prepared for the next reaction period.
