  2. Integrated gasification fuel cell cycle - Wikipedia

    en.wikipedia.org/wiki/Integrated_Gasification...

    The moving-bed gasifier (e.g., Lurgi) operates at moderate temperature levels, and with moderate oxygen and steam supply requirements. The cold gas efficiency achieved by this gasifier is higher, circa 90%, and its syngas product stream will have methane content nominally in the 4-5% (vol) range. [5]

  3. Gasification - Wikipedia

    en.wikipedia.org/wiki/Gasification

    The produced gas leaves the gasifier at a high temperature, and most of this heat is often transferred to the gasification agent added in the top of the bed, resulting in an energy efficiency on level with the counter-current type. Since all tars must pass through a hot bed of char in this configuration, tar levels are much lower than the ...

    en.wikipedia.org/wiki/Fluid_catalytic_cracking

    The next major step was to develop a continuous process rather than the semi-batch Houdry process. That step was implemented by advent of the moving-bed process known as the Thermofor Catalytic Cracking (TCC) process which used a bucket conveyor-elevator to move the catalyst from the regeneration kiln to the separate reactor section.

  5. Circulating fluidized bed - Wikipedia

    en.wikipedia.org/wiki/Circulating_fluidized_bed

    Circulating fluidized bed technology can be implemented in many different fields ranging from oil and gas to power stations. This technology is highly sought after due to its numerous benefits. Some of the popular applications of circulating fluidized bed are circulating fluidized bed scrubber and circulating fluidized bed gasification system.

  6. Fluidized bed combustion - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_combustion

    FBC smoke tube boiler. Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

  7. Integrated gasification combined cycle - Wikipedia

    en.wikipedia.org/wiki/Integrated_gasification...

    An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas . It can then remove impurities from the syngas prior to the electricity generation cycle.

  8. Chemical looping combustion - Wikipedia

    en.wikipedia.org/wiki/Chemical_looping_combustion

    Chemical looping combustion (CLC) is a technological process typically employing a dual fluidized bed system. CLC operated with an interconnected moving bed with a fluidized bed system, has also been employed as a technology process. In CLC, a metal oxide is employed as a bed material providing the oxygen for combustion in the fuel reactor.

  9. Fluidized bed reactor - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_reactor

    A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst ) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.
