    • The present invention relates to a process for preparing 2,3-dimethylbutane which comprises contacting in a reaction zone isobutane with a supported catalyst comprising a tungsten hydride and a support comprising an aluminium oxide, so as to form a reaction mixture comprising 2,3-dimethylbutane. The contacting essentially leads to performing a metathesis reaction of the isobutane, with a very high specificity in the formation of 2,3-dimethylbutane. The catalyst is preferably a tungsten hydride grafted onto a support based on aluminium oxide. The support can be chosen from aluminium oxides, mixed aluminium oxides and modified aluminium oxides. The reaction mixture can be isolated and preferably subjected to one or more fractionating operations in order to recover 2,3-dimethylbutane and optionally one or more other components of the reaction mixture, such as C5+ alkanes. The process can comprise isolating from the reaction mixture the C5+ alkanes including 2,3-dimethylbutane as a single component, which can be blended with gasoline to enhance the gasoline octane number, or be used as a gasoline blendstock. At least one separated fraction containing 2,3-dimethylbutane can be isolated from the single component, which can be blended with gasoline to enhance the gasoline octane number, or be used as a gasoline blendstock.

    • 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.
