Abstract: A catalyst, useful for oxidative dehydrogenation of ethane, comprising molybdenum, vanadium, tellurium, tantalum, and oxygen, prepared using a stage hydrothermal synthesis procedure, is provided. The catalyst comprises from 30 to 50 wt. % amorphous content and may be combined with a support/carrier material to form a catalyst material. The described catalysts and catalyst materials demonstrate high selectivity for ethylene at higher temperatures, show little to no decline in conversion and selectivity over time, and do not appear to be sensitive to low residual oxygen concentrations.

Abstract: A method and a system for converting ethane to ethylene are provided. An exemplary method includes providing a feed stream including the ethane and oxygen to an oxidative dehydrogenation reactor and converting at least a portion of the ethane to ethylene in the oxidative dehydrogenation reactor to provide a reactor effluent stream including ethane, ethylene, and oxygen, acetylene, or both. The method includes cooling the reactor effluent stream to form a cooled effluent stream and providing the cooled effluent stream to an oxygen removal reactor including an ODH catalyst bed. A deoxygenation stream including water and an alcohol is provided to the oxygen removal reactor to form a deoxygenated effluent.

Abstract: A feed stream including ethane is flowed to a purification unit that includes a first oxidative dehydrogenation catalyst. The feed stream is contacted with the first oxidative dehydrogenation catalyst at a first temperature to reduce a concentration of impurities in the feed stream to produce a purified feed stream. The purified feed stream is flowed to an oxidative dehydrogenation unit that includes a second oxidative dehydrogenation catalyst. The purified feed stream is contacted with the second oxidative dehydrogenation catalyst in the presence of oxygen at a second temperature greater than the first temperature to dehydrogenate ethane to produce a product stream that includes ethylene.

Abstract: An apparatus for hydrocarbon conversion, the apparatus including a reactor and a reactor insert secured and disposed within an interior cavity of the reactor, is described. The reactor is configured to permit addition of a feed stream comprising a hydrocarbon at an upstream end of the reactor and to permit discharge of a product stream at a downstream end of the reactor. The reactor insert is configured to provide heat to the interior cavity to promote conversion of hydrocarbons as the feed stream moves from the upstream end of the reactor to the downstream end of the reactor. The products of the conversion reaction are discharged at the downstream end as part of the product stream. A method for hydrocarbon conversion using the apparatus is also described.

Abstract: The product distribution from an oxidative dehydrogenation process can be altered by co-feeding different ratios of ethanol to steam, in the range of 0.01 to 0.50 ethanol:steam to an oxidative dehydrogenation reactor. Increasing the ethanol to steam ratio was found to: increase ethylene yield; decrease acetic acid yield; increase, or decrease, or cause no effect on CO or CO2 yield; and have negligible effect on ethane conversion. The feed ethanol is converted to carbonaceous products without negatively effecting the catalyst activity.

Abstract: Methods and a reactor system for producing acetic acid in a selective oxidation (SO) reactor are provided. An example method includes providing a fresh feed stream to the SO reactor, wherein the fresh feed stream includes a methane feed stream, a carbon dioxide feed stream, and a steam feed stream. Acetic acid is formed in the SO reactor. An acetic acid product stream is separated from a reactor effluent stream in a scrubber. A recycle gas stream is obtained from the scrubber. At least a portion of the recycle gas stream is combined into the fresh feed stream to the SO reactor.

Abstract: A fixed bed reactor system for the oxidative dehydrogenation of ethane, comprising a catalyst bed wherein the catalyst capacity profile increases along the length of catalyst bed from the upstream end to the downstream end. The catalyst bed may include one or more sections, across one or more fixed bed reactors, that are identified by a change in catalyst capacity. Catalyst capacity, or the ability to convert ethane into ethylene, may be altered by changing the dilution ratio, void fraction, and or the 35% conversion temperature. A method for loading a fixed bed reactor with an increasing catalyst capacity is also described.

Abstract: The present disclosure relates to limiting the production of acetic acid in an oxidative dehydrogenation process to convert ethane to ethylene. The process of oxidative dehydrogenation includes feeding acetic acid, along with ethane and oxygen into an oxidative dehydrogenation reactor where contact with a catalyst leads to conversion of the ethane into ethylene and acetic acid. By including acetic acid in the feed, the amount of acetic acid produced may be limited and the ratio of ethylene produced to ethane consumed may increase.
