Cascade Reaction Online Decoupling Micro Fluidized Bed Reaction Analyzer

Featuring a dual-stage series reaction unit structure, the MFBRA-D achieves fractional reaction and in-situ transmission of reactive substances to decouple complex reaction processes. It is ideal for multi-stage reaction decoupling, intermediate product trapping, and parameter optimization.

Key Specifications

Reactor Stages 2-stage (DTF + MFB)
Transfer Mode Online pneumatic conveying
Stage 1 Drop-tube furnace (downer reactor)
Stage 2 Micro-fluidized bed reactor
Temperature Control Independent per stage

Working Principle

Granular samples are placed into the top-tier falling furnace reactor to initiate the primary reaction. By adjusting gas flow, the particle residence time is controlled. Once primary gas generation ceases, a solenoid valve delivers a pulse of gas to instantly transport the intermediate solid reactants from the bottom of the falling furnace into the secondary micro fluidized bed reactor to start the secondary reaction. The two stages can maintain different temperatures, atmospheres, and flow rates.

Features & Advantages

Two-Stage Reaction Coupling

Integrates a drop-tube furnace (DTF) with a micro-fluidized bed reactor to achieve staged decoupling of complex reaction processes.

In-Situ Pneumatic Transfer

Online sample transfer via pneumatic conveying achieves in-situ decoupling, avoiding changes in intermediate product properties — a common issue in traditional decoupling research.

Independent Stage Control

Each stage can independently control temperature, atmosphere, and flow rate for precise reaction parameter optimization.

Typical Applications

The MFBRA-D is trusted by leading research institutions and industrial labs worldwide for a wide range of applications.

  • Coal pyrolysis-coupled combustion reaction
  • Tar staged pyrolysis reaction (500°C → 750°C)
  • Volatile combustion and char combustion decoupling
  • Multi-stage reaction mechanism analysis
