Patent Number: US 8084658
Title: Integrated preparation of benzene and ammonia from aliphatic hydrocarbons and nitrogen
Inventor(s): Mueller, Ulrich; Freiberger, Harald
Patent Assignee(s): Basf Se, Germany
Source: PCT Int. Appl., 16 pp. CODEN: PIXXD2
Language: German

Abstract:
The invention relates to a method for integrated production of aroms. and ammonia by reacting a gaseous stream A containing at least 1 C1 to C6 aliphatic compound and nitrogen in the presence of at least 1 catalyst, wherein in one reaction, the C1 to C6 aliphatic compound is non-oxidatively converted into aroms. and the hydrogen released in said process is converted in a further reaction into ammonia.  Thus, a gas mixture containing 58% methane and 42% nitrogen was introduced into a reactor having 198 mg catalyst containing ruthenium and molybdenum at 650 degrees in the rate of 25 mL/min to give a product showing ammonia 10 mg/kg and benzene 30 mg/kg.

Please note:  Abstracts for patent records in CAplus are routinely enhanced to better describe the claimed invention. In this example, CAS enhanced the abstract using additional information found in the patent. CAS also indexed the PCT patent publication WO2008062028 as the first published record of the invention.
