    Abstract: The present invention relates to a process for converting methane into a higher alkane mixture, preferably a liquid alkane mixture, comprising (C 3+ ) alkanes having 3 carbon atoms and more, preferably (C 4+ ) alkanes having 4 carbon atoms, especially (C 5+ ) 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.

    Abstract: A process is disclosed for the conversion of lower molecular weight hydrocarbons, such as methane, into higher molecular weight hydrocarbon products, such as hydrocarbons having between 4 and 29 carbons. The process includes forming hydrated electrons, such as by mixing the lower molecular weight hydrocarbons with water and contacting the mixture with an energy source to form hydrated electrons. The hydrated electrons react with the methane to form hydrogen and higher molecular weight hydrocarbon products. Also disclosed is a related process for converting higher molecular weight hydrocarbons to lower molecular weight hydrocarbons by forming a mixture of higher molecular weight hydrocarbons and water and contacting the mixture with an energy source to form hydrated electrons that react with the higher molecular weight hydrocarbons to form hydrogen and lower molecular weight hydrocarbon products.

    Abstract: Increased recovery of propane, butane and other heavier components found in a natural gas stream is achieved by installing an absorber upstream from an expander and a separator. The separator is downstream from the expander and returns the liquid stream generated by the separator back to the absorber. Additionally, the recovery of propane, butane and other heavier components is enhanced by combining the upper gas stream from a distillation column with the upper gas stream from the absorber prior to injecting this combination into the separator. The upper gas stream removed from the separator is then subsequently processed for the recovery of a predominantely methane and ethane gas stream while the bottom liquid stream from the absorber is subsequently distilled for the generation of a stream consisting predominantely of propane, butane and other heavy hydrocarbon components. Alternate embodiments include an additional reflux separator in the system, or substitution of an additional absorber for the separator.
