摘要:
A method comprising: providing a first halogen stream; providing a first alkane stream; reacting at least a portion of the first halogen stream with at least a portion of the first alkane stream in a first reaction vessel to form a first halogenated stream; providing a second alkane stream comprising C 2 and higher hydrocarbons; providing a second halogen stream; and reacting at least a portion of the second halogen stream with at least a portion of the second alkane stream in a second reaction vessel to form a second halogenated stream.
摘要:
Alcohols, ethers and olefins are manufactured from alkanes by mixing an alkane and bromine in a reactor to form alkyl bromide and hydrogen bromide. The alkyl bromide only or the alkyl bromide and the hydrogen bromide are directed into contact with the metal oxide to form an alcohol and/or ether, or an olefin and metal bromide. The metal bromide is oxidised to form original metal oxide and bromine, both of which are recycled.
摘要:
A method of synthesizing hydrocarbons from smaller hydrocarbons includes the steps of hydrocarbon halogenation, simultaneous oligornerization and hydrogen halide neutralization, and product recovery, with a metal-oxygen cataloreactant used to facilitate carbon-carbon coupling. Treatment with air or oxygen liberates halogen and regenerates the cataloreactant.
摘要:
The present invention provides a method for synthesizing alcohols and/or ethers, from alkanes comprising: providing a quantity of an alkane selected from the group consisting of methane, ethane, propane, butane, and isobutane; providing a quantity of bromine; mixing the alkane and the bromine and thereby forming an alkyl bromide and hydrogen bromide; reacting the alkyl bromide and the hydrogen bromide with a metal oxide and thereby forming alcohol and/or ether and a metal bromide; oxidizing the metal bromide to form the original metal oxide and bromine; recycling the metal oxide; and recycling the bromine. The present invention further provides a method for converting methanol to dimethyl ether.

An apparatus for converting alkanes to alcohols and/or ethers is disclosed said comprising: a reactor; means for directing methane and bromine into the reactor to produce methyl bromide and hydrogen bromide; a first converter comprising a solid metal oxide; means for directing alkyl bromide from the reactor into contact with the metal oxide of the converter to form an alcohol and/or ether, and the metal bromide; a second converter comprising a solid metal oxide; means for directing hydrogen bromide from the reactor into contact with the metal oxide of the second converter to form water and metal bromide; means for converting the metal bromides from the first and second converters to form the original metal oxides and bromine; and means for recycling the metal oxides and the bromine.
摘要:
In a method of converting alkanes to their corresponding alcohols, ethers, olefins, and other hydrocarbons, a vessel comprises a hollow, unsegregated interior defined first, second, and third zones. In a first embodiment of the invention oxygen reacts with metal halide in the first zone to provide gaseous halide; halide reacts with the alkane in the second zone to form alkyl halide; and the alkyl halide reacts with metal oxide in the third zone to form a hydrocarbon corresponding to the original alkane. Metal halide from the third zone is transported through the vessel to the first zone and metal oxide from the first zone is recycled to the third zone. A second embodiment of the invention differs from the first embodiment in that metal oxide is transported through the vessel from the first zone to the third zone and metal halide is recycled from the third zone to the first zone. In a third embodiment of the invention the flow of gases through the vessel is reversed to convert the metal oxide back to metal halide and to convert the metal halide back to the metal oxide.
