Abstract: A system for producing at least one hydrocarbon fuel from a carbonaceous material, the system including: a nuclear power plant; a hydrocarbon fuel manufacturing plant, including at least an electrolyzer unit for producing a first hydrogen stream from water and electric power provided by the nuclear power plant, and an hydrocarbon fuel synthesis unit, the nuclear power plant supplying power to a power distribution grid to which electric power consumers other than the hydrocarbon manufacturing plant are electrically connected; a buffer storage of at least one given hydrocarbon fuel; a reforming unit for producing a second hydrogen stream from the at least one given hydrocarbon fuel, and a device to feed the at least one given hydrocarbon fuel to the reforming unit at a controlled feed flow rate; a device to feed the hydrocarbon fuel synthesis unit with the first hydrogen stream at a first controlled flow rate and with the second hydrogen stream at a second controlled flow rate; and a device to control the fi

Abstract: A method for skeletal isomerization of linear olefins to iso-olefins, e.g., n-butenes to isobutylene, over a catalyst comprising medium pore zeolite, e.g., a zeolite selected from ZSM-22, ZSM-23, and ZSM-35. Treatment of the zeolite with dicarboxylic acid, e.g., oxalic acid, significantly reduces aging rate and increases cycle length of the catalyst.

Abstract: A process is disclosed for the highly selective skeletal isomerization of linear olefin-containing organic feeds to iso-olefins at high levels of feed conversion wherein linear olefins, e.g., n-butenes, are contacted with catalyst comprising ZSM-22 having a crystal size whose largest dimension is no greater than 0.5 micron. The process is carried out under isomerization conditions to produce iso-olefins of corresponding carbon number, e.g., isobutene. High overall iso-olefin yields thus can be obtained, even at relatively low temperatures.
