摘要: Abstract In the present study sublimation of large solid carbon dioxide particles inside fluidized beds fine is investigated. A model which takes surface area sublimable into account used to describe kinetics. Based on this model, results different experiments, namely single particle experiments using a precision scale, batch in laboratory-scale bed and continuous larger circulating are compared. The main focus evaluate influences size, inert material, temperature superficial gas velocity, respectively.
