Note(s)
In this subclass, the following terms or expressions are used with the meanings indicated:[2,3,6]"solid particles" includes such particles whether catalysts, reactants or inert in solid, semi-solid or pasty state;"fluidised particles" means finely divided solid particles lifted and agitated by a stream of fluid;"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";"processes conducted in the presence of solid particles" does not include processes wherein the only solid particles present are formed during the reaction In this subclass, tradenames that are often found in scientific and patent literature have been used in order to define precisely the scope of the groups
