Abstract
A method for converting one or more hydrocarbons includes feeding a fluid comprising one or more light alkanes to a reactor system, and producing one or more oxygenates from the one or more light alkanes in the reactor system. The reactor system comprises a reactor containing at least one catalyst, the at least one catalyst comprises one or more oxides of molybdenum, vanadium, niobium, cerium, titanium, zirconium, and one or more precious metals. An oxygenate productivity is higher than about 50 g/kg cat.h after 100 hours of time on stream.
Claims31
A method for converting one or more hydrocarbons to oxygenates,
- the method comprising:
- feeding a fluid comprising one or more light alkanes, an oxidative gas comprising oxygen and nitrogen, and water to a reactor system, wherein the reactor system comprises a reactor containing at least one catalyst, wherein the at least one catalyst comprises one or more oxides of molybdenum, vanadium, niobium, cerium, titanium, zirconium, silicon or a combination thereof, and one or more precious metals comprising ruthenium, rhodium, palladium, osmium, iridium, platinum, gold, or any combination thereof,
- producing one or more oxygenates from the one or more light alkanes in the reactor system as an output stream;
- separating the one or more oxygenates from the output stream in a separation system in fluid communication with the reactor system, and
- recycling at least a portion of any unconverted light alkanes from the separation system to the reactor system.

A system for converting one or more hydrocarbons, the system comprising:
- a reactor system, wherein the reactor system comprises at least one reactor containing at least one catalyst, the at least one catalyst comprises one or more oxides of molybdenum, vanadium, niobium, cerium, titanium, zirconium, silicon, or a combination thereof and one or more precious metals comprising ruthenium, rhodium, palladium, osmium, iridium, platinum, gold, or any combination thereof, and wherein the reactor system is configured to react one or more light alkanes in the presence of the catalyst to produce one or more oxygenates comprising acetic acid in an output stream;
- a separation system in fluid communication with the reactor system, where the separation system is configured to separate the one or more oxygenates from the output stream and recycle at least a portion of any unconverted light alkanes to the reactor system.
