  • Publication number: 20240093865
    Abstract: Various aspects provide for a multistage fluidized bed reactor, particularly comprising a volatilization stage and a combustion stage. The gas phases above the bed solids in the respective stages are separated by a wall. An opening (e.g., in the wall) provides for transport of the bed solids from the volatilization stage to the combustion stage. Active control of the gas pressure in the two stages may be used to control residence time. Various aspects provide for a fuel stream processing system having a pretreatment reactor, a combustion reactor, and optionally a condensation reactor. The condensation reactor receives a volatiles stream volatilized by the volatilization reactor. The combustion reactor receives a char stream resulting from the removal of the volatiles by the volatilization reactor.

  • Publication number: 20240083281
    Abstract: An apparatus for an electric vehicle having a battery interface, an inverter, a switch device and a control device. The inverter has a first terminal for connecting the inverter to the battery interface and a second terminal for connecting the inverter to a switch terminal. The inverter is formed to convert a DC voltage applied to the first terminal into an AC voltage and to provide the latter to the second terminal. The switch device has the switch terminal that connects the switch device to the second terminal and an energization interface for energizing a further electric vehicle coupled to the energization interface.

  • Publication number: 20210245130
    Abstract: Various aspects provide for a fluidized bed reactor comprising a container having a bed of bed solids and a splashgenerator configured to impart a directed momentum to a portion of the bed solids. A bedwall may separate the bed solids into first and second reaction zones, and the directed momentum may be used to transfer bed solids from one zone to the other. A return passage may provide for return of the transferred bed solids, providing for circulation between the zones. A compact circulating bubbling fluidized bed may be integrated with a reactor having first and second stages, each with its own fluidization gas and ambient. A multistage reactor may comprise a gaswall separating at least the gas phases above two different portions of the bed. A gaslock beneath the gaswall may provide reduced gas transport while allowing bed transport, reducing contamination.

  • Publication number: 20210180787
    Abstract: Aspects provide for volatilizing a biomass-based fuel stream, removing undesirable components from the resulting volatiles stream, and combusting the resulting stream (e.g., in a kiln). Removal of particles, ash, and/or H2O from the volatiles stream improves its economic value and enhances the substitution of legacy (e.g., fossil) fuels with biomass-based fuels. Aspects may be particularly advantageous for upgrading otherwise low-quality biomass to a fuel specification sufficient for industrial implementation. A volatilization reactor may include a fluidized bed reactor, which may comprise multiple stages and/or a splashgenerator. A splashgenerator may impart directed momentum to a portion of the bed to increase bed transport via directed flow.

  • Patent number: 8313544
    Abstract: In a process for the synthetic generation of methane from a feed gas mixture, a feed gas mixture including carbon monoxide, hydrogen, water vapor, CO2, volatile hydrocarbons comprising C2 and higher, unsaturated C2 components and aromatic hydrocarbons in the range of 1 to 10 vol % is provided. The feed gas mixture is contacted with a fluidized bed catalyst having catalyst particles having a catalytic active component selected from the group consisting of a metal, a metal compound and combinations thereof. The contacting occurs at an elevated temperature in the range of 250 to 450° C., a feed gas pressure in the range of 0.8 to 70 bar, a gas hourly space velocity of 1000 to 50000 h?1, and a concentration of H2/CO in the gas mixture in the range of 0.25 to 5.
