Abstract
A method comprising providing a halogen stream; providing a first alkane stream; reacting at least a portion of the halogen stream with at least a portion of the first alkane stream to form a halogenated stream, wherein the halogenated stream comprises alkyl monohalides, alkyl polyhalides, and a hydrogen halide; providing a second alkane stream; and reacting at least a portion of the second alkane stream with at least a portion of the alkyl polyhalides to create at least some additional alkyl monohalides.
Claims20
A system for forming hydrocarbons comprising:
- a halogenation reactor, wherein the halogenation reactor receives a quantity of halogen and a first quantity of alkane and produces a halogenated product;
- a reproportionation reactor, wherein the reproportionation reactor receives the halogenated product and a second quantity of alkane and produces at least some alkyl monohalide and a quantity of hydrogen halide;
- and
- an oligomerization reactor comprising an oligomerization catalyst, wherein the oligomerization reactor receives alkyl monohalide and produces a quantity of hydrocarbon product and a second quantity of hydrogen halide.
