Erzeugung von Acetylen durch thermische Spaltung von Kohlenwasserstoffen mittels hocherhitzten Wasserstoffes. (WLP‐Verfahren der Knapsack‐Griesheim AG)

Abstract: Als Energietrager fur die Spaltung von Kohlenwasserstoffen wird im Lichtbogen hocherhitzter und teilweise atomarer Wasserstoff verwendet. Zur Umsetzung wird ein Uberschui3 an gasformigem Kohlenwasserstoff, z. B. verdampftes Benzin, von ca. 15% verwendet. Dieser wird zusammen mit den Nebenprodukten der Spoltung wieder zugefuhrt, so da8 aIs Endprodukte nur Acetylen, Xthylen, Methan und Wasserstoff erhalten werden. Die Ausbeute an Acetylen und Xthylen betrogt bei Verwendung von Benzin uber 70 Gew.-%. Bei einem Pr… Show more

“…The second major synthon 343 can be synthesized in three steps from acetone and acetylene (accessible via electric arc pyrolysis of methane or from wood-derived charcoal through calcium carbide). 501 First, a reaction to 2-methylbut-3-yn-2-ol is conducted, 502 followed by oxidation 503 and completed by enolization and protection of the afforded hydroxy groups. 504 Both synthons were linked through a Mukaiyama aldol reaction followed by in situ base-induced dehydration affording the a,b-unsaturated ketone 344.…”

“…Examples of this type of process include the production of acetylene and unsaturated compounds from hydrocarbon (12,17,18,35,41,58,66,80,81,83,86,96,101), tetrafluoroethylcne from tetrafluoromethane (12), nitrogen fluorides (12,14), cyanogen (56, 99), hydrazine, hydrocyanic acid, (13,31,33,40,56,57,59,99,105), hydroxylamine, and formaldehyde (15,77).…”

“…The production of acetylene and olefins (ethylene and propylene) during pyrolysis of liquid hydrocarbons in a plasma jet was investigated on an installation of capacity up to 4,000 kW (35,86). Kinetic and thermodynamic analyses of hydrocarbon decomposition have dictated the conditions under which the process should be conducted (701).…”
