Abstract:
The invention relates to a method for producing synthesis gas (5), wherein a hydrocarbon-containing coke-oven gas (2) and a carbon-dioxide-containing converter gas (4) are introduced into a first reaction zone (Z1) and hydrogen, contained in the hydrocarbon-containing coke-oven gas (2), is at least partially reacted with carbon dioxide in order to form water and the water is thermally reacted with the hydrocarbon in order to produce synthesis gas, which contains carbon monoxide and hydrogen. In a second reaction zone (Z2), an oxygen-containing gas (3) is introduced and thermal energy is produced by means of said oxygen-containing gas and part of the hydrogen from the first reaction zone (Z1), wherein the thermal energy produced in the second reaction zone (Z2) is supplied to the first reaction zone (Z1).
Abstract:
Methods and systems are disclosed for extracting hydrogen and/or liquid fuel from a compound comprising carbon, oxygen, and hydrogen ("C-O-H"). The compound may include cellulose, lignin, and/or hemicellulose, for example. The compound may include a waste stream that includes at least one C-O-H compound. Water may be combined with the C-O-H compound to produce a wet form of the C-O-H compound. The wet form of the C-O-H compound may be transferred into a reaction processing chamber. The wet form of the C-O-H compound may be heated within the reaction chamber such that elements of the C-O-H compound dissociate and react, with one reaction product comprising at least hydrogen gas and/or liquid fuel. Some embodiments may utilize non-oxidation reactions to produce the hydrogen and/or liquid fuel, such as hydrous pyrolysis reactions. The hydrogen gas and/or liquid fuel may be utilized to generate electrical power, heat, or power different types of engines.

Abstract:
A process and a system for generating synthesis gas from hydrocarbons and water are described. In further details of the process and the system, synthesis gases are generated in any desired ratios of CO to hydrogen and/or synthetic functionalized and/or non-functionalized hydrocarbons. By means of this process, a hydrocarbon-containing fluid can be converted into a synthesis gas having a variable hydrogen content without generating significant amounts of CO 2 . Furthermore, hydrogen and carbon in various forms can be obtained as byproducts.
Abstract:
A pre-reformer (10) comprises a non-electrically conducting gas tight duct (12) and an electrically conducting wire (14) arranged in the duct (12). The electrically conducting wire (14) is electrically isolated from the duct (12). The duct (12) has an inlet (16) for receiving a hydrocarbon fuel at a first end (18) and an outlet (20) for supplying a pre-reformed hydrocarbon fuel at a second end (22). At least the inner surface (24) of the duct (12) is chemically inert with respect to the hydrocarbon fuel. An electrical power supply (26) is electrically connected to the electrically conducting wire (14) and a control means (28) controls the supply of electrical current through the electrically conducting wire (14) to maintain the electrically conducting wire (14) at a temperature to provide selective thermal decomposition of higher hydrocarbons in the hydrocarbon fuel. The performer reduces coking in associated fuel cells and other parts of a fuel cell system.
Abstract:
A system and process are provided for extracting a substance from a molecular combination. The process comprises heating the molecular combination to dissociate the molecular combination into cations and anions, moving the cations and anions through a magnetic field to separate cations and anions, and isolating cations from anions with a barrier. The system comprises a non- conductive conduit for guiding an ionized particle stream, a magnetic field source for creating a magnetic field through which the ionized particle stream moves, and a barrier located in the conduit. The ionized particle stream has a velocity relative to the conduit, and the magnetic field source is oriented relative to the velocity of the ionized particle stream so that cations are separated from anions as the ionized particle stream moves through the magnetic field. The barrier is oriented in the conduit so that cations are isolated from anions after separation.
Abstract:
The invention concerns a method for producing a gas rich in hydrogen by thermal pyrolysis of hydrocarbons which consists in carrying out, in a reactor (R) a catalyst-free thermal cracking to pyrolyze a fuel selected so as to produce either a gas rich in hydrogen and free of carbon monoxide, or a gas rich in hydrogen and containing carbon monoxide and in using said gas effluents during pyrolysis and inert with respect to the cell as fuel at the burner (B) to heat the reactor so as to bring it to a reaction temperature, and which consists, subsequently, in burning the powder carbon produced in the reactor (R) during the pyrolysis reaction either to produce carbon monoxide or to produce carbon dioxide. The invention is useful in particular for supplying hydrogen to fuel cells and for producing synthesis gas.
