Fluidized Bed Reactor | ReaktiLabX 19
Fluidized Bed Reactor ReaktiLabX 19 supports a solid bed of catalytic particles on an upward gas flow, enabling simple catalyst loading and removal. This fluidized bed reactor is approximately 1 meter long with a 25 mm ID, featuring a replaceable porous metal gas diffusion plate and a disengaging zone at the top. Separate heaters, a multipoint thermocouple, and a heated cyclone separator support stable operation. Reaction products are cooled by a condenser and collected in a 600 mL product receiver, with pressure and temperature monitored and controlled digitally.
The Fluidized Bed Reactor ReaktiLabX 19 is a bench-scale reactor system in which a solid bed of catalytic particles is supported by an upward gas flow. This fluidized bed reactor makes it simple to load and remove catalyst, which is useful when the solids bed needs frequent removal and replacement. It enables high conversion with a large throughput and offers strong mixing and heat transfer characteristics.
Product Overview
The Fluidized Bed Reactor ReaktiLabX 19 is used extensively in chemical processes that depend on design characteristics such as heat transfer or diffusion. A fluidized bed has distinct advantages over a packed bed. These include greater temperature control, absence of hot spots in the bed, uniform catalyst dispersion, and longer catalyst life. Employing a fluidized bed requires adequate mixing between the particles and the suspending fluid. Fluidized bed technique is used in almost all large commercial gas-solid systems. Applications include catalytic hydrocarbon cracking, Fischer-Tropsch synthesis, and related high molecular weight petroleum fractions. Coal, biomass, and other waste sources can be gasified in a fluidized bed to produce synthesis gas. This fluidized bed reactor is built for laboratory-scale study of these processes.

Construction and Design
The Fluidized Bed Reactor ReaktiLabX 19 is built around a reactor approximately one meter long with a 25 mm inner diameter. The lower portion of the reactor incorporates an easily replaced porous metal gas diffusion plate. The top of the reactor widens abruptly to form a disengaging zone for the fluidized bed. Separate heaters are provided for both the main reactor and the disengaging zone. A multipoint thermocouple monitors the internal reactor temperature distribution. A heated cyclone separator or filter is fitted immediately downstream of the reactor to capture fines resulting from particle attrition. Reaction products are cooled by a condenser and collected in a 600 mL product receiver. System pressure is maintained by a pressure regulator. Gas feed to the reactor is controlled manually by adjustment of flowmeter valves. Pressure is monitored by pressure gauges and can also be displayed digitally. Temperature of the reactor chamber is monitored at different locations along the column. Temperature is digitally controlled and maintained by a Process Controller. This construction makes the fluidized bed reactor suitable for studying gas-solid reaction systems at laboratory scale.
