    摘要: The present invention relates to a process for converting methane into a higher alkane mixture, preferably a liquid alkane mixture, comprising (C3+) alkanes having 3 carbon atoms and more, preferably (C4+) alkanes having 4 carbon atoms, especially (C5+) alkanes having 5 carbon atoms and more. The process comprises: - a stage (1) comprising contacting methane with a metal catalyst (C1) capable of producing, in contact with alkane, reactions involving the splitting and recombining of C-C and/or C-H and/or C-metal bonds, so as to form by a non-oxidative methane coupling reaction a mixture (M1) comprising ethane and hydrogen, - preferably a stage (2) comprising fractionating the mixture (M1) so as to separate and to isolate the ethane, and - a stage (3) comprising, preferably simultaneously, (i) contacting the mixture (M1) or preferably the ethane isolated in stage (2) with a metal catalyst (C2) capable of producing, in contact with alkane, reactions involving the splitting and recombining of C-C and/or C-H and/or C-metal bonds, said catalyst being identical to or different from catalyst (C1), so as to form by simultaneous ethane self- and cross-metathesis reactions a mixture (M2) comprising methane and the higher alkane mixture, and (ii) fractionating the mixture (M2) so as to separate and to isolate said higher alkane mixture, preferably in liquid form, and particularly the methane which is preferably recycled into stage (1). The hydrogen produced in stage (1) is preferably separated and isolated in stage (2) and then used for various applications and stages, e.g. for producing thermal and/or electrical energies preferably employed to run the process.

    摘要: The present invention relates to a process for converting methane into a liquid mixture of (C 3+ ) alkanes having 3 carbon atoms and more, preferably (C 4+ ) alkanes having 4 carbon atoms and more, especially (C 5+ ) alkanes having 5 carbon atoms and more. It comprises a stage (1) comprising converting methane into acetylene, performed by submitting methane to a thermal cracking reaction, so as to form a reaction mixture (M1) comprising acetylene and hydrogen, a stage (2) comprising converting acetylene into ethane, performed by contacting the acetylene or the reaction mixture (M1) previously obtained with hydrogen in the presence of a hydrogenation catalyst (C1), so as to form a reaction mixture (M2) comprising ethane, a stage (3) comprising simultaneous ethane self- and cross-metathesis reactions performed by contacting the ethane or the reaction mixture (M2) previously obtained with a metal catalyst (C2) capable of producing, in contact with alkane, reactions involving the splitting and recombining of C-C and/or C-H and/or C-metal bonds, so as to form a reaction mixture (M3) comprising methane and a mixture of the (C 3+ ), preferably the (C 4+ ), especially the (C 5+ ) alkanes, and a stage (4) comprising fractionating the reaction mixture (M3) so as to separate and to isolate said mixture in liquid form. Preferably, the methane is also separated in stage (4) and recycled into stage (1) for methane conversion into acetylene
