High-Pressure Micro Fluidized Bed Reaction Analyzer
Gas-solid reaction studies under ambient and elevated pressures with online analysis for pressure-dependent reaction mechanism derivation.
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
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.
