Fluid Bed Reactors

Procedyne offers specially-designed high-temperature fluid bed reactors for processing powders and granular materials up to 1200°C, in virtually any atmosphere, be it oxidizing, reducing, inert, or otherwise. Procedyne units perform well in various chemical reactions, including:
  • Calcinations
  • Activations
  • Oxidations
  • Reductions
  • Pyrolysis
  • CVD
We have designed and built fluid bed reactors for many different materials, including catalysts, metal powders, metal oxides, carbons, ceramics, glasses, pigments, fine chemicals, polymers, foodstuffs and many others.

Our systems are designed and built for reliable, long-term commercial operation. Materials of construction are selected for high-temperature strength, corrosion resistance, and compatibility with respect to product purity.

Procedyne systems operate on electricity, natural gas or fuel oil, thermal fluids or steam, and are highly efficient, even at high temperature.

Precise temperature control, combined with uniform and complete fluidization, provide for reproducible, high-quality product with extremely high yield.

An array of batch and continuous reactors can be custom designed to each application.

Bed Temperature Uniformity Test Data
20" Pilot Fluid Bed Reactor

 View
The data presented was obtained in a test program in Procedyne's 20" diameter cylindrical pilot fluid bed processor at the Procedyne Process Technology Laboratory.

The test was preformed to illustrate the temperature uniformity achievable in a Procedyne fluid bed. The pilot unit is an indirectly-heated system, with capability for preheating of the fluidizing gas. In this test, no gas preheating was utilized, and the maximum bed temperature was targeted, to present the most difficult conditions for temperature uniformity.

The temperatures were recorded using a three-point measurement in a radial direction, with the points of measurement at the vessel centerline [A], vessel wall [C], and midpoint between the two [B]. The temperature probe was traversed in the axial direction from top to bottom (nominal 2" above the gas distributor) in 4" increments. Temperatures were recorded in the downward and upward traverses of the fluidized bed. The time duration for these traverses was roughly one hour. The data shown in the table below is from the downward traverse; the upward traverse yielded values within the tolerance displayed in the downward traverse
