Abstract X‐ray absorption is presented as a unique tool for the study of the fundamentals of gas fludization. For example, bed‐density profiles, valuable indexes of the quality of fluidization, are readily determined by means of X‐ray absorption. No internal probes, to interfere with the normal action within a fluidized bed, are involved. As an initial application of X‐ray absorption to fluidization, the results of a study of the effect of mode of distribution of gas to a fluidized bed are presented. The importance of this variable, only superficially discussed in previous literature, is clearly shown by these results. Application of X‐ray absorption to other chemical engineering operations is readily conceivable.
