The invention relates to a process and an apparatus for producing an olefin-containing feed stream for a steam reforming plant. According to the invention, the olefin-containing hydrocarbon starting material is for this purpose heated, vaporized and catalytically hydrogenated. The hydrogenation product stream obtained is separated in a separation apparatus into a gaseous reforming feed stream, which is fed to a steam reforming plant, and a gaseous recycle stream. Here, the entry temperature of the hydrogenation input stream into the hydrogenation reactor is regulated via the degree to which it is heated and/or via the size of the recycle stream. Safe operation of the hydrogenation reactor over a wide range of olefin contents in the hydrocarbon feed is made possible in this way.

A direct carbonaceous material to power generation system integrates one or more solid oxide fuel cells (SOFC) into a fluidized bed gasifier. The fuel cell anode is in direct contact with bed material so that the H.sub.2 and CO generated in the bed are oxidized to H.sub.2O and CO.sub.2 to create a push-pull or source-sink reaction environment. The SOFC is exothermic and supplies heat within a reaction chamber of the gasifier where the fluidized bed conducts an endothermic reaction. The products from the anode are the reactants for the reformer and vice versa. A lower bed in the reaction chamber may comprise engineered multi-function material which may incorporate one or more catalysts and reactant adsorbent sites to facilitate excellent heat and mass transfer and fluidization dynamics in fluidized beds. The catalyst is capable of cracking tars and reforming hydrocarbons.

An electrochemical reactor designed to increase the efficiency of hydrogen production from faeces and urine (excrement) is disclosed. Said reactor comprises two half-cells separated in a selective manner, a membrane systems separating the half-cells (comprising a proton-exchange and an anion-exchange membranes) and a system of electrical bridges that allow two mutually perpendicular electrical fields to be formed, with the electrical field in the horizontal direction between the two half-cells being greater than the vertical electrical field generated within the anode. The half-cells have a configuration of two resistances in series, which allows the potential of each compartment to be controlled in an independent and complementary manner by adjusting the conductivity of the solutions in the half-cells. Said configuration allows the consumption of energy to form hydrogen to be significantly reduced in comparison with conventional electrolytic cells using water in an alkaline medium by combining the chemical processes of electrolysis (anode) and the law of chemical equilibrium (cathode).
