Beschreibung
Zusammenfassung: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).
