Title: (DE) Verfahren zur Herstellung von Ethylen
(EN) Process for the production of ethylene
(FR) Procédé pour la production d'éthylène
Abstract: front page image
(EN) A conventional two-stage pyrolysis scheme is used to convert methane containing feed to produce acetylene as an intermediate product which is immediately in situ hydrogenated into ethylene as the final product by hydrogen transfer medium, preferably supplied by higher alkanes, in one process unit - an integrated reactor comprising multiple reaction zones.
