.~.~ Using H acceptor or Cr-, Mo-, or W-containing catalyst
DEFINITION
Classification: 585/433
Using H acceptor or Cr-, Mo-, or W- containing catalyst:
(under subclass 430) Subject matter wherein a material is employed which forms a compound with the hydrogen removed from the feedstock or which contains, chromium, molybdenum, or tungsten in free or combined form.
(1) Note. The hydrogen acceptor may be an element of a compound, the compound being a hydrocarbon or a nonhydrocarbon.
SEE OR SEARCH THIS CLASS, SUBCLASS:
257, for a hydrogen-exchange disproportionation process in which the hydrocarbon which becomes more saturated is a desired product of the process.
380, 442, 442, 617+, and 654+, for other dehydrogenation processes which use a hydrogen acceptor.
403, for aromatic manufacture where the hydrogen acceptor is embodied in the apparatus used.
900, for aromatic manufacture where a nonhydrocarbon acceptor is recycled, e.g., after rehabilitation.
