Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...B01J 20/00-B01J 38/00, 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] - In groups Fulltext...

[4] - 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 Fulltext...
