Notes

(1)	In groups B 01 J 20/00 to B 01 J 31/00, 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]

(2)	In groups B 01 J 21/00 to B 01 J 38/00, the following term is used with the meaning indicated:

-	"catalyst" covers also a carrier forming part of the catalyst. [2,5]

(3)	Attention is drawn to the definitions of groups of chemical elements following the title of section C. [2]

(4)	In groups B 01 J 20/00 to B 01 J 38/00, in the absence of an indication to the contrary, classification is made in the last appropriate place. [2,5]

(5)	In groups B 01 J 20/00 to B 01 J 38/00, if a carrier is considered of interest, further classification is made in group B 01 J 32/00. [4]

(6)	In groups B 01 J 21/00 to B 01 J 31/00, if a regeneration or reactivation process is considered of interest, further classification is made in group B 01 J 38/00. [4]

(7)	Classification of the:

-

-	forms or physical properties;

-	preparation or activation;

-	regeneration or reactivation

of catalysts according to more than one of main groups B 01 J 21/00 to B 01 J 31/00 is made in the following general groups:

-	B 01 J 32/00 for such carriers;

-	B 01 J 35/00 for such forms or physical properties;

-	B 01 J 37/00 for such preparation or activation;

-	B 01 J 38/00 for such regeneration or reactivation. [4,5]

(8)

Pure compounds or elements, or their recovery from solid sorbent compositions, filter aid compositions, or catalysts, are classified in the appropriate subclass 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 B 01 J 20/00 or B 01 J 35/00.

Note

In groups B 01 J 21/00 to B 01 J 31/00, it is desirable to add the indexing codes of groups B 01 J 101:00 to B 01 J 105:00. The indexing codes should be linked. [6]
