Catalytic Fluidized Bed Reactors Catalytic Fluidized Bed Reactors

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 possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

Characteristics Fluidized-bed gasifiers may differ in ash conditions (dry or agglomerated/slagging) and in design configurations for improving char use. Also, depending on the degree of fluidization and bed height, these types of reactors sometimes are also named as circulating fluidized bed reactors, and/or transport reactors.

data for gas-solid reactions under isothermal conditions, a thermogravimetric fluidized bed reactor (TGFBR) was designed. Using this novel fluidised bed, gravimetric measurements and high heating rate, the thermal conversion of biomass was investigated. Using a thermogravimetric analyser (TGA) as a fixed bed and the TGFBR as a fluidized bed,

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and ...

A fluidized bed may be defined as the bed of solid particles behaving as a fluid. It operates on the principal that when an evenly distributed air is passed upward through a finely divided bed of solid particles at low velocity, the particles remain undisturbed, but if the velocity of air flow is steadily increased, a stage is reached when the individual particles are suspended in the air stream.

Moving bed reactors are catalytic reactors in which the catalyst moves through the reactor along with the reactants. They are open systems and operate at steady state . The animation below shows the operation of a moving-bed reactor. Reactants (green) and catalyst (white) enter the top of the reactor and move through the vessel.

As an extension of the fluidized bed family of separation processes, the flash reactor (FR) (or transport reactor) employs turbulent fluid introduced at high velocities to encourage chemical reactions with feeds and subsequently achieve separation through the chemical conversion of desired substances to different phases and streams. A flash reactor consists of a main reaction chamber and an ...

which is important in the design procedure for any fixed-bed catalytic reactor. A bed of catalyst pellets is generally considered as if it were a continuous homogeneous media, and the physical properties of the packed bed or system are assigned values on the basis of a weighted average of each of the individual constituents making up the system.

Gasification is a process that converts organic- or fossil fuel-based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide.This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.The resulting gas mixture is called syngas (from synthesis gas) or producer gas and is itself a fuel.
