In this subclass, the following terms or expressions are used with the meanings indicated:

–

"solid particles" includes such particles whether catalysts, reactants or inert in solid, semi-solid or pasty state; [2]

–

"fluidised particles" means finely divided solid particles lifted and agitated by a stream of fluid; [2]

–

"fluidised-bed technique" means fluid-solid contacting technique in which finely divided particles are lifted and agitated by a rising stream of fluid, said stream having such a speed as to form a lower dense phase (the "bed") and an upper dilute fluidised phase of "fluidised particles"; [2]

–

"processes conducted in the presence of solid particles" does not include processes wherein the only solid particles present are formed during the reaction. [3]
