The following patent record is from the CAplusSM database.


Patent Number: US 8258357
Title: Production of propylene and olefins from butane feedstocks using a CATADIENE dehydrogenation unit
Inventor(s): Dukandar, Kerman; Spence, David; Panditrao, Sunil
Patent Assignee(s): Lummus Technology Inc., USA
Source: U.S. Pat. Appl. Publ., 7 pp., Chemical Indexing Equivalent to 153:431889 (WO) CODEN: USXXCO
Language: English

This invention relates to an integrated process for the efficient production of olefins from C4 feedstocks comprising butane and more particularly to a method of producing propylene and butadiene. The process combines a dehydrogenation unit with an olefin conversion unit to convert butane feedstock to propylene and butadiene products. The combined CATADIENE-OCT process produces yields of propylene from normal butane in excess of 70%.

Please note:  Titles and abstracts for patent records in CAplus are routinely enhanced to better describe the claimed invention. In this example, CAS enhanced both the abstract and title using additional information found in the patent. The original title of the publication is Production of propylene from butane. For the CAplus record, this title was enhanced to read Production of propylene and olefins from butane feedstocks using a CATADIENE dehydrogenation unit.
