Definitions
- Methane is a major constituent of natural gas and also of biogas.
- World reserves of natural gas are constantly being increased, e.g., due to new discoveries, etc.
- a significant portion of the world reserves of natural gas is in remote and offshore locations where gas pipelines cannot be economically justified or reinjection of the gas is not feasible.
- much of the natural gas produced along with oil at remote locations is flared.
- methane produced in petroleum refining and petrochemical processes Since flaring of methane produces CO 2 , future flaring of natural gas and methane may be prohibited or restricted. Thus, significant amounts of natural gas and methane are available to be utilized.
- methane can be sweetened, dried, and transported to market; however the sweetened and dried methane product is typically sold at 1/2 to 1/3 the price of liquid fuels on a BTU basis.
- the Fischer Tropsch (FT) reaction involves the synthesis of liquid hydrocarbons or their oxygenated derivatives from the mixture of carbon monoxide and hydrogen, which can be obtained, e.g., by the partial combustion of methane or by the gasification of coal. This synthesis is carried out with metallic catalysts such as iron, cobalt, or nickel at high temperature and pressure. The overall efficiency of the FT reaction and subsequent water gas shift chemistry is estimated at about 15% to 30%, when allowing for the energy required to make the conversion. While FT does provide a route for the liquefication of coal stocks, it is not adequate in its present level of understanding and production for commercial conversion of methane-rich stocks to liquid fuels. FT requires a heavily discounted natural gas source to be economical. Additionally, a FT plant is expensive and bulky, and therefore not suitable for use in many remote locations, such as on an offshore oil rig where natural gas comprising methane is routinely flared.
- the methyl bromide stream 40 and a methyl bromide recycling stream 100 are combined in the presence of aluminum bromide for alkyl bromide conversion 70 to produce a an output stream 72.
- the output stream 72 is separated in separator 75 into higher hydrocarbon (C2 - C5) product stream 80, the methyl bromide recycling stream 100, an HBr stream 90, and the methane stream 10b.
- bromine can be produced by a bromine steaming out process, such as Kubierschky's distillation method; see, e.g., Kirk-Othmer, Encyclopedia of Chemical Technology, Fourth Edition, volume 4, pages 548 through 553.
- Kubierschky's distillation method such as Kirk-Othmer, Encyclopedia of Chemical Technology, Fourth Edition, volume 4, pages 548 through 553.
- Other methods for recovering bromine from bromide-containing solutions are described, e.g., in US 3181934, US 4719096, US 4978518, US 4725425, US 5158683, and US 5458781.
- bromine can be recovered from brines by treatment with chlorine to oxidize the bromide to bromine; and processes for electrolytic conversion of bromide to bromine are known.
- This invention meets the above-described needs by providing processes for producing C2+ hydrocarbons, such process comprising: (a) producing HBr and methyl bromide using a bromine source and a gas stream comprising methane; (b) heating at least some of the methyl bromide in the presence of a catalyst to produce additional HBr and C2+ hydrocarbons; (c) processing at least some of the HBr to produce Br 2 ; (d) using at least some of the produced Br2 from (c) as at least a portion of the bromine source in (a).
- This invention provides such processes wherein: the processing of (c) comprises combining at least some of the HBr and an oxygen source in the presence of a cerium-containing compound at at least about 315 0 C to produce Br 2 ; the processing of (c) comprises combining at least some of the HBr, at least some of the additional HBr, and an oxygen source in the presence of a cerium-containing compound at at least about 315°C to produce Br 2 ; and/or wherein such processes comprise recovering heat from (c) and using the recovered heat to provide at least some of the heating in (a), (b), or both.
- C2+ hydrocarbons includes all hydrocarbons having two or more carbon atoms, including without limitation ethane, propane, butane, ethylene, propene, heptane, isooctane, cyclopentane, ethyl benzene, and the like.
- processing at least some of the HBr to produce Br 2 comprises combining at least some of the HBr and an oxygen source in the presence of a cerium- containing compound at at least about 315 0 C to produce Br 2 ;
- the processing can be conducted, e.g., at at least about 315°C (600 0 F) to about 1000 0 C (1832 0 F), or at at least about 315 0 C (600°F) to about 538 0 C (1000 0 F).
- the upper temperature can be limited by the ability of the cerium-containing compound, or other catalyst, and/or of the processing equipment to withstand the temperature of operation.
- Other processes useful in processes of this invention include, for example, reacting HBr and methane at elevated temperatures in an oxygen atmosphere in the presence of a lanthanum catalyst to generate methyl bromide and water.
- the methyl bromide can be converted to C2+ hydrocarbons and/or other organic products, generating HBr as a co-product.
- methanol and HBr can be used to generate methyl bromide and water.
- the methyl bromide can be converted to C2+ hydrocarbons and/or other organic products, generating HBr as a co-product.
- the co-product HBr can be recycled for use in processes of this invention.
