Process for converting ethane into liquid alkane mixtures

摘要: The invention relates to a process for converting ethane into liquid mixture of (C4+) alkanes having 4 carbon atoms and more, preferably (C5+) 5 more. comprises stage (1) comprising simultaneous self- cross-metathesis reactions carried out by contacting with metal catalyst (C1) capable producing, in contact alkane, involving the splitting recombining C-C and/or C-H C-metal bonds, so as form reaction (Ml) methane (C4+), alkanes, (2) separating isolating from (Ml), (3) non-oxidative coupling thus isolated (C2) C- said being identical or different (Cl), (M2) hydrogen, optionally (4) (M2), (5) recycling going on continuing forming (6) form, performed combination particularly simultaneously (2).
