    Abstract: The present invention provides a process for the oxidative dehydrogenation of ethane to ethylene, the process at least comprising the steps of: (a) providing an ethane-containing stream (10); (b) subjecting the ethane-containing stream (10) provided in step (a) to oxidative dehydrogenation, thereby obtaining a stream (20) containing at least ethylene, water and acetic acid; (c) separating acetic acid from the stream (20) obtained in step (b), thereby obtaining a concentrated acetic acid stream (60) and a first ethylene-enriched stream (40); (d) subjecting the concentrated acetic acid stream (60) obtained in step (c) to hydrogenation thereby obtaining an ethanol-containing stream (80); and (e) subjecting the ethanol-containing stream (80) obtained in step (d) to dehydration thereby obtaining a second ethylene-enriched stream (90).

    Abstract translation: 本发明提供了乙烷氧化脱氢成乙烯的方法,该方法至少包括以下步骤:(a)提供含乙烷的物流(10); (b)使步骤(a)中提供的含乙烷物流(10)进行氧化脱氢,从而获得至少含有乙烯,水和乙酸的物流(20); (c)从步骤(b)中获得的物流(20)中分离乙酸,由此得到浓缩乙酸物流(60)和第一乙烯富集物流(40); (d)将步骤(c)中获得的浓缩乙酸流(60)进行氢化,从而得到含乙醇的物流(80); 和(e)使步骤(d)中获得的含乙醇的流(80)脱水,从而获得第二个富含乙烯的流(90)。

    Abstract: The present invention provides a method of preparing acetylene (C2H2), the method at least comprising the steps of: a) providing a methane-containing stream; b) subjecting the methane-containing stream provided in step a) to non-catalytic pyrolysis, thereby obtaining carbon and hydrogen; c) reacting the carbon obtained in step b) with CaO, thereby obtaining CaC2 and CO; d) reacting the CaC2 obtained in step c) with H2O, thereby obtaining acetylene (C2H2) and Ca(OH)2; e) decomposing the Ca(OH)2 obtained in step d), thereby obtaining CaO and H2O; f) using the CaO as obtained in step e) in the reaction of step c).
