High-Pressure Micro Fluidized Bed Reaction Analyzer

High-Pressure Micro Fluidized Bed Reaction Analyzer

Equipped with a unique pressurized reaction cell, the HP-MFB carries out gas-solid reaction studies under ambient and elevated pressures via the micro-fluidized bed method. It couples with an online analysis system for pressure-dependent reaction mechanism derivation, applicable to a wide range of reaction types including decomposition, roasting, calcination, combustion, gasification, reduction, and oxidation.

Key Specifications

Pressure Mode Ambient to elevated (high-pressure)
Pressure Control Back-pressure valve at outlet
Sample Injection High-pressure pulse feeding
Injection Timing Millisecond-scale pulse valve
Online Detection Coupled mass spectrometry

Working Principle

Pressure is maintained by introducing high-pressure gas regulated by a back-pressure valve at the outlet end. Pressurized online sample injection is achieved via a high-pressure pulse feeding system. Prior to injection, the pulse unit pressure is raised to reaction pressure + 0.1–0.2 MPa. A high-frequency pulse valve fires on a millisecond scale, utilizing the pulse gas stream to entrain and convey particles into the pressurized bed.

Features & Advantages

Pressurized Reaction Cell

Unique pressurized cell design enables isothermal reaction processes under varying pressure conditions from ambient to elevated pressures.

High-Pressure Pulse Feeding

Millisecond-scale high-frequency pulse valve enables online sample injection under high-pressure conditions with precise pressure matching.

Pressure-Dependent Analysis

Investigates pressure effects on reaction processes from both product variation and kinetic parameter perspectives.
