Multi-reaction process for forming a product gas from solid carbonaceous material
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.
COST EFFECTIVE PLASMA COMBINED HEAT AND POWER SYSTEM
A method of generating syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a cupola. The cupola operates on inductive heat alone, chemically assisted heat, or plasma assisted heat. Cupola operation is augmented by employing carbon or graphite rods to carry electrical current into the metal bath that is influenced by the inductive element. The method includes the steps of providing a cupola for containing a metal bath; and operating an inductive element to react with the metal bath. A combination of fossil fuel, a hazardous waste, and a hazardous material is supplied to the cupola. A plasma torch operates on the metal bath directly, indirectly, or in a downdraft arrangement. Steam, air, oxygen enriched air, or oxygen are supplied to the metal bath. A pregassifier increases efficiency and a duct fired burner is added to a simple cycle turbine with fossil fuel augmentation.
Bulk Energy Storage Process
A multi stage set of molten salt based processes for coal gasification, recovery of sulfur from hydrogen, capture of CO.sub.2 from gases and processes to store generated electrical energy for later use when it is needed in which excess power can be used to decarbonize fossil fuel to produce hydrogen that can be stored, sequester CO.sub.2, and regenerate the hydrogen back to electricity using an advanced power cycle.
Arrangement and method for preparing a gas
The invention relates to an arrangement for preparing a gas in a closable reactor by supplying the reactor with carbon-based biomass or chopped wood material, such as chips, in substantially oxygen-free conditions, by allowing the biomass or wood material to gasify at a high temperature, and by recovering the gas generated in a gasification reaction. In that the arrangement the reactor has its interior defined by a feed pipe whose inlet end is closable with a shut-off valve, especially with a ball valve, and whose outlet end adjoins a heatable gasification dome, biomass or chopped wood material is delivered from the feed pipe's inlet end into the reactor's interior, the reactor's interior is supplied with free water/water vapor in its supercritical state, which is optionally prepared catalytically by splitting water/water vapor, the biomass or wood material is conveyed into a gasification space of the reactor's interior, which is in connection with the heated gasification dome and which is adapted to have existing conditions selected in a manner such that the water present in said gasification space is present in its supercritical state, and the gas generated in the gasification reaction is recovered.
