Based on these results, the wall effects – the key mechanism resulting in the unique behavior of micro fluidization – are analyzed. Other sections discuss gas and solid mixing characteristics in terms of gas residence time distribution, gas backmixing, and solids mixing.
Final sections focus on presentations of the so-called micro fluidized bed reaction analyzer (MFBRA) – a powerful tool for catalyst screening, process development, optimization of reaction parameters, studies of reaction mechanism and kinetics, among many other purposes. The book describes, in detail, the MFBRA’s system design characteristics, analytic methodologies and various applications in thermochemical and catalytic reaction analysis.
