Isothermal Differential Reaction Analyzer
Novel thermal reaction analysis instrument for gas-solid reaction research at any temperature with online mass spectrometry coupling.
Isothermal Differential Reaction Analyzer
The MFBRA-B/S is a novel thermal reaction analysis instrument widely applicable to gas-solid reaction research. It tests reaction rates at any temperature, analyzes reaction parameters, and reveals reaction mechanisms. Extensively used for granular materials involved in or catalyzing reactions such as decomposition, roasting, calcination, combustion, gasification, reduction, oxidation, absorption, and adsorption — particularly suitable for thermally unstable substances.
Key Specifications
Working Principle
A micro fluidized bed serves as a differential reactor, with inert particles (silica sand) or catalyst particles as the fluidizing medium. Granular reactants are instantly fed online via pneumatic transport. The generated reaction gas is purified, and the outlet gas flow and concentration are monitored in real-time using mass spectrometry. The analysis software converts data into molar amounts or mass changes of generated gases, quantifying generation rates and deriving reaction kinetic parameters. By repeating tests at different temperatures, activation energy and the pre-exponential factor can be calculated using the Arrhenius equation.
Features & Advantages
Online Micro-Sample Feeding
Achieves online feeding of micro-granular materials at reaction temperature via instantaneous pneumatic conveying.
Intrinsic Reaction Characterization
Micro fluidized bed technology enhances mass transfer, minimizes gas backmixing, and suppresses external diffusion — ensuring the reaction process is closer to its intrinsic kinetics.
Rapid Isothermalization
Maximum heating rate up to 10,000 °C/s enables reaction studies under strict isothermal conditions.
Typical Applications
The MFBRA-B/S is trusted by leading research institutions and industrial labs worldwide for a wide range of applications.
- Graphite combustion reaction kinetics
- Coal pyrolysis and semi-coke gasification
- Ca(OH)₂ CO₂ absorption reaction
- CO reduction of CuO
