CAS databases provide millions of journal article references from more than 10,000 major scientific journals worldwide, patent and patent family references from 63 patent authorities around the world, and other reputable web sources.

The following patent record is from the CAplusSM database.


Patent Number: US 8163808
Title: Acetylene enhanced conversion of syngas to Fischer-Tropsch hydrocarbon products
Inventor(s): Kibby, Charles Leonard; Cheng, Minquan
Patent Assignee(s): Chevron U.S.A Inc., USA; Commonwealth Scientific and Industrial Research Organisation
Source: U.S. Pat. Appl. Publ., 15 pp. CODEN: USXXCO
Language: English

The invention relates to a method for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products, the method comprising: (a) providing synthesis gas to a F-T reactor; (b) providing acetylene to the F-T reactor, the molar ratio of the acetylene to synthesis gas being at least 0.01; (c) reacting the synthesis gas and acetylene under suitable reaction conditions, in the presence of a catalyst, to produce F-T hydrocarbon products; and (d) recovering the F-T hydrocarbon products.

Please note:  Abstracts for patent records in CAplus are routinely enhanced to better describe the claimed invention. CAS enhanced the abstract using additional information found in the patent. In this example, the U.S. granted patent lists Charles Leonard Kibby, Minquan Cheng, Yun Lei, David Lawrence Trimm and William L. Schinski as the inventors. CAS indexed the published application US 20090170965 as the first published record of the invention which only included Charles Leonard Kibby and Minquan Cheng as inventors at that time.
