What is claimed is: 1. A method for use in conjunction with a process of hydrocarbon conversion comprising: providing a first stream comprising a halide; contacting the first stream with a solid material, wherein the solid material retains at least a portion of the halide in the first stream; removing at least a portion of the halide retained by the solid material from the solid material; and contacting at least a portion of the halide removed from the solid material with a hydrocarbon feed, and reacting at some hydrocarbons in the hydrocarbon feed with at least a portion of the halide removed from the solid material to form a second stream comprising an alkyl halide. 2. The method of claim 1 wherein the solid material comprises a reactive adsorbent. 3. The method of claim 2 wherein the reactive adsorbent comprises at least one material selected from the group consisting of: copper (I) bromide, iron (II) bromide, silver bromide, carbon, carbon fullerenes and nano-tubular carbon. 4. The method of claim 1 wherein the solid material is a reactive solid, wherein the reactive solid comprises at least one material selected from the group consisting of: copper (II) oxide, silver, copper, lithium, magnesium, and an alkylide metal. 5. The method of claim 1 wherein the hydrocarbon feed comprises at least one hydrocarbon selected from the group consisting of: methane, ethane, propane, butane, isobutene, pentane, hexane, and cyclohexane. 6. The method of claim 1 further comprising: separating any higher alkyl halides from the second stream, wherein the higher alkyl halides comprise any alkyl halide with a plurality of halogen atoms; reproportionating the higher alkyl halides with at least some of the hydrocarbon feed to form at least some alkyl monohalide; and combining at least some of the alkyl monohalide with the second stream. 7. The method of claim 1 wherein the solid material comprises an adsorbent, wherein the adsorbent comprises at least one structure selected from the group consisting of: a molecular sieve, a mesoporous material, a zeolite, a silica, an alumina, an aluminosilicate, a magnesia, an activated carbon, a metal bromide, and a metal oxide. 8. A method for use in conjunction with a process of hydrocarbon conversion comprising: providing a first stream comprising a halide; contacting the first stream with a solid material, wherein the solid material retains at least a portion of the halide in the first stream; removing at least a portion of the halide retained by the solid material; reacting at least a portion of the halide removed from the solid material with a hydrocarbon feed to form a second stream, wherein the second stream comprises an alkyl halide; and contacting the second stream with a catalyst to cause a coupling reaction, wherein the coupling reaction creates at least a product stream. 9. The method of claim 8 wherein the solid material comprises an adsorbent, wherein the adsorbent comprises at least one structure selected from the group consisting of: a molecular sieve, a mesoporous material, a zeolite, a silica, an alumina, an aluminosilicate, a magnesia, an activated carbon, a metal bromide, and a metal oxide. 10. The method of claim 8 wherein the solid material comprises a reactive adsorbent, wherein the reactive adsorbent comprises at least one material selected from the group consisting of: copper (I) bromide, iron (II) bromide, silver bromide, carbon, carbon fullerenes and nano-tubular carbon. 11.

The method of claim 8 wherein the second stream is contacted with the catalyst in a plurality of switched fixed beds. 15. A method for use in conjunction with a process of hydrocarbon conversion comprising: providing a first stream comprising a halide; contacting the first stream with a solid material, wherein the solid material retains at least a portion of the halide in the first stream; removing at least a portion of the halide retained by the solid material; reacting at least a portion of the halide removed from the solid material with a hydrocarbon in a feed comprising hydrocarbons to form a second stream, wherein the second stream comprises an alkyl halide; contacting the second stream with a metal oxide to cause a coupling reaction, wherein the coupling reaction produces a metal halide and a product comprising at least one component selected from the group consisting of: an olefin, an alcohol, an ether, and an aldehyde; and contacting the metal halide with an oxidizer to produce at least some of the metal oxide and at least some regenerated halide. 16.
