2802. REIS, T. [Theoretical and Experimental Contributions to the Study of Fluid Catalyst Systems.] Bull. assoc. franc. techniciens pétrole, No. 76, 1949, pp. 3-44; U.O.P. co. Lib. Bull., Oct. 5, 1949. This article is composed of 3 parts. The 1^{st} part discusses the theory of fluid catalysis and reviews the work of other investigators. Semiempirical formulas are introduced for making the following calculations: (a) The length of time the particles are in a reactor; (b) the loss of charge; (c) the distinction between aggregative and particulate fluidization; (d) the initial expansion of the solid particle bed; (e) the efficacy of fluidization; (f) the loss of charge in the case of horizontal or vertical flow of the dispersed suspensions. The 2d part describes a new experimental method for directly controlling the behavior of dispersed catalyst suspensions. The 3d part is devoted to new theoretical conceptions of fluidized systems.
