Note(s) The term "solid particles" is to be read as covering such particles whether catalysts, reactants or inert in solid, semi-solid or pasty state. [2] "Fluidised particles" are to be understood as finely divided solid particles lifted and agitated by a stream of fluid. "Fluidised-bed technique" relates to 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] The expression "processes conducted in the presence of solid particles" is considered not to include processes wherein the only solid particles present are formed during the reaction. [3]

|  | B01J 20/00 - B01J 37/00 |
Note(s) In the absence of an indication to the contrary, a solid sorbent composition, filter aid composition or catalyst is classified in the last appropriate place. The same rule applies for the preparation or the treatment of solid sorbent compositions, filter aid compositions, or catalysts. [2] Pure compounds or elements, or their recovery from solid sorbent compositions, filter aid compositions, or catalysts, are classified in the appropriate sub-class for chemical compounds or elements. However, when it is explicitly stated that the pure compound or element, in a particular form, is especially useful as a solid sorbent, filter aid, or catalyst, it is further classified in group Fulltext... Hierarchy... Expanded...B01J 20/00 or group Fulltext... Hierarchy... Expanded...B01J 35/00. [2] Inventions dealing with the preparation, regeneration or form of catalysts according to more than one of main groups Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy...

[2] The term "catalyst" is to be understood as covering also a carrier forming part of the catalyst.

Note(s) Ion-exchange covers all processes whereby ions are exchanged between the solid exchanger and the liquid to be treated and wherein the exchanger is not soluble in the liquid to be treated.
