A device for reacting an organic starting material to yield a gas that includes hydrogen has a feed device, a tubular furnace with an entry zone, an interior space, an axis of rotation and an exit side, and a water feed arranged by the feed device or entry zone and controllable as a function of the content of hydrogen in the gas mixture. The feed device feeds the starting material in the region of the entry zone into the interior space of the tubular furnace, from which a solid material and a gas mixture is discharged. The tubular furnace has a compensator for different thermal expansions of a first zone and a second zone. A gas-conducting system includes a gas monitor for the content of hydrogen in the gas mixture.

A rotating air distributor for rotary reactors such as rotary kilns for the gasification of biomass and other carbonaceous materials for efficient mixing and maximum conversion of solid biomass and other carbonaceous materials into synthesis fuel gas is disclosed. The invention includes a gas distribution port comprises of one main supply from which several discharge nozzles emerge at different angles and at different locations along the length of the reactor to provide distribution of gas throughout the intended length of the reactor. The discharge of gas from the gas distribution port is adjusted by the variable position of a plug inside the port that can be adjusted during the operation of the kiln to achieve optimum gas-solid interaction along the length of the reactor. The rotating action of the gas distribution port also facilitates and eases the passage of reacted biomass solid and other carbonaceous material residue through the reactor.

摘要:
A method and apparatus for converting carbonaceous material to a stream of carbon rich gas, comprising heating a slurry feed containing the carbonaceous material in a hydrogasification process using hydrogen and steam, at a temperature and pressure sufficient to generate a methane and carbon monoxide rich stream in which the conversion time in the process is between 5 and 45 seconds. In particular embodiments, the slurry feed containing the carbonaceous material is fed, along with hydrogen, to a kiln type reactor before being fed to the fluidized bed reactor. Apparatus is provided comprising a kiln type reactor, a slurry pump connected to an input of the kiln type reactor, means for connecting a source of hydrogen to an input of the kiln type reactor; a fluidized bed reactor connected to receive output of the kiln type reactor for processing at a fluidizing zone, and a source of steam and a source of hydrogen connected to the fluidized bed reactor below the fluidizing zone. Optionally, a grinder can be provided in the kiln type reactor.
摘要:
A method and reactor system is configured as an appliance for the destruction of residential and building waste to form hydrogen-rich syngas. This syngas is used to power a fuel cell for the generation of electric power, steam and heat or cooling for use in residences and buildings as well as hydrogen fuel for vehicles. The waste conversion rector that carries out the endothermic reactions of steam reforming is heated with the waste heat and electrical power. Alternatively, this reactor can be heated by a natural gas burner. This reactor is designed as a rotary drum, into which are placed bags of waste that can consist of normal garbage as well as toilet solid waste. Glass and metal are not melted in this drum and are recovered as completely sterilized at the end of the process cycle.
摘要:
The process and system of the invention converts carbonaceous feedstock such as coal, hydrocarbon oil, natural gas, petroleum coke, oil shale, carbonaceous-containing waste oil, carbonaceous-containing medical waste, carbonaceous-containing hazardous waste, carbonaceous-containing medical waste, and mixtures thereof into electrical energy without the production of unwanted greenhouse emissions. The process and system uses a combination of a gasifier, e.g., a kiln, operating in the exit range of at least 700° to about 1600° C. (1300–2900° F.) to convert the carbonaceous feedstock and a greenhouse gas stream into a synthesis gas comprising mostly carbon monoxide and hydrogen without the need for expensive catalysts and or high pressure operations. One portion of the synthesis gas from the gasifier becomes electrochemically oxidized in an electricity-producing fuel cell into an exit gas comprising carbon dioxide and water. The latter is recycled back to the gasifier after a portion of water is condensed out. The second portion of the synthesis gas from the gasifier is converted into useful hydrocarbon products.
摘要:
A process for producing liquid steel is disclosed. Carbon monoxide and oxygen may be combusted in a high temperature reactor. Iron and iron oxide materials, along with scrap steel if desired, may be placed in the high temperature reactor. Carbon dioxide produced in the high temperature reactor may be circulated through a back reactor vessel. Coke masses may be placed in the back reactor vessel. The coke may be formed by circulating heated carbon monoxide counter current to crushed coal in a rotary kiln. The carbon dioxide circulated through the back reactor vessel reacts with the coke to form carbon monoxide. The carbon monoxide may be conveyed to the high temperature reactor to be combusted with oxygen to produce the heat for forming the liquid steel.
