Note(s)

  1. 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]
  2. "Fluidised particles" are to be understood as finely divided solid particles lifted and agitated by a stream of fluid.
  3. "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]
  4. 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]

Note(s)

  1. 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]
  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 B01J 20/00 or group B01J 35/00[2]
  3. Inventions dealing with the preparation, regeneration or form of catalysts according to more than one of main groups B01J 21/00-B01J 31/00 are classified in the general group B01J 35/00 for such forms or in the general group B01J 37/00 for such methods. [2]
  4. Metal salts having an anion composed of metal and oxygen only, e.g. molybdates, are considered as chemically bound mixtures of the component metal oxides. [2]
  5. The term "catalyst" is to be understood as covering also a carrier forming part of the catalyst. [2]
  6. Attention is drawn to the definitions of groups of chemical elements following the title of Section C. [2]
