.~.~.~ Plural zones of similar function (same chamber)
DEFINITION
Classification: 208/169
(under subclass 165) Processes in which (1) a plurality of fluid streams separately contact a single stream of solids flowing through a series of gravitating compact bed zones or (2) a single stream of fluid serially contacts a plurality of gravitating compact bed zones wherein the solids flow in the zones is at least partially in parallel, all the contact zones being within the same chamber.
(1) Note. Where the mineral oil conversion reaction is named in each of the zones, the original patent is classified above in subclasses 49+ or 78+. However, plural zone unnamed reactions of the same type are classified herein whether the reactions are of the conversion or the regeneration type. The reaction or regeneration zones are generally associated with a common solids supply.
SEE OR SEARCH THIS CLASS, SUBCLASS:
49+, for processes of subjecting mineral oil to plural successive conversions. (See (1) Note).
78+, for mineral oil conversion processes involving plural parallel stages of chemical conversion. (See (1) Note).
