Measurement of the axial dispersion coefficient of cohesive powders in rotary kilns
, 2016 While continuous rotary calcination is a widely used thermal treatment in large-scale catalyst manufacturing, fundamental understanding of the process is absent from scientific literature. Thus, the goal of this research is to improve fundamental understanding of rotary calcination processes to aid in scale-up.
