DEFINITION

Classification: 585/616

By dehydrogenation:

(under subclass 601) Subject matter wherein hydrogen is removed from a feedstock to synthesize the diolefin product.

SEE OR SEARCH THIS CLASS, SUBCLASS:

257, for a process where a hydrocarbon is dehydrogenated by transfer of hydrogen to another hydrocarbon, the acceptor compound being a material desired for recovery.

430, 440+ and 654+, for dehydrogenation processes for the production of other types of hydrocarbon.

613, for a diolefin synthesis process which includes carbon removal as well as hydrogen removal.
