DEFINITION

Classification: 208/113

(under subclass 106) Processes in which a catalytic material is employed.

(1) Note. To be classified in this or indented subclasses the process must include (a) the treatment of a specific mineral oil identified by some definite physical or chemical property thereof, such as boiling range, specific gravity, etc., or (b) the use of a specifically identified catayltic material. Merely identifying the feed as a naphtha, as boiling within the gas-oil range or the use of a catalyst of a particular size is not itself sufficient to cause classification in this or indented subclasses. Processes excluded by this note are classified below in subclasses 146+ which provides for mineral oil processes including the contacting of the oil with solids.

SEE OR SEARCH THIS CLASS, SUBCLASS:

146+, for manipulative contacting processes which are of general application even though claimed as "catalytic cracking" (see (1) Note).
