The methods and systems include a method of hydrating an olefin that may include emulsifying an olefin gas in a water stream in a high shear device under high shear conditions to produce a dispersion; and contacting the dispersio

대표청구항 ▼

1. A method of hydrating an olefin comprising: emulsifying an olefin gas in a water stream in a high shear device under high shear conditions to produce a dispersion; andcontacting the dispersion with a catalyst to hydrate the olefin gas and form an alcohol. 2. The method of claim 1 wherein said high shear conditions comprise local temperatures and local pressures that are substantially higher than bulk temperature and bulk pressure in the high shear device. 3. The method of claim 1, wherein the dispersion comprises gas bubbles having a mean diameter of less than about 5 μm. 4. The method of claim 1, wherein the olefin gas comprises one or more olefins comprising from 2 to 8 carbon atoms. 5. The method of claim 1, wherein the high shear device comprises a rotor and a stator. 6. The method of claim 1, wherein the emulsifying comprises subjecting said olefin gas and water to a shear rate in the range of about from 20,000 s−1 to about 100,000 s−1. 7. The method of claim 1, wherein the catalyst is selected from the group consisting of phosphoric acid, sulfonic acid, sulfuric acid, a zeolite, and combinations thereof. 8. The method of claim 1, wherein the alcohol is selected from the group consisting of ethanol, isopropanol, butanol, propanol, and combinations thereof. 9. A method of hydrating an olefin comprising: forming a dispersion of an olefin gas and a water stream in a high shear device comprising a rotor and a stator; andintroducing said dispersion into a fixed-bed reactor to hydrate the olefin gas and form an alcohol, wherein said fixed-bed reactor comprises a hydration catalyst. 10. The method of claim 9, wherein the dispersion comprises olefin gas bubbles having a mean diameter of less than about 5 μm. 11. The method of claim 9, wherein the hydration catalyst is selected from the group consisting of phosphoric acid, sulfonic acid, sulfuric acid, a zeolite, and combinations thereof. 12. The method of claim 9, wherein the alcohol is selected from the group consisting of ethanol, isopropanol, butanol, propanol, and combinations thereof. 13. The method of claim 9, wherein at least one of the rotor and the stator is configured with a toothed surface. 14. The method of claim 9, wherein said high shear device comprises a rotor tip, and said device is configured to operate at a flow rate of at least 300 L/h and at a tip speed of at least about 23 m/sec. 15. A method of hydrating an olefin comprising: forming a dispersion of an olefin gas and a water stream in a high shear device comprising a generator, the high shear device operating at high shear conditions;transferring at least a portion of the dispersion from the high shear device to a vessel;introducing a hydration catalyst into the vessel; andoperating the vessel at reaction conditions to promote hydration of the olefin gas in the portion of the dispersion to produce an alcohol. 16. The method of claim 15 further comprising mixing a hydration catalyst with the water stream. 17. The method of claim 15, wherein said high shear device comprises a rotor and a stator separated by a shear gap in the range of from about 0.02 mm to about 5 mm, and wherein the dispersion comprises gas bubbles having a mean diameter of less than about 5 μm. 18. The method of claim 15 comprising utilizing more than one generator. 19. The method of claim 15 further comprising utilizing at least two high shear devices. 20. The method of claim 19, wherein the shear rate provided by one of the at least two high shear devices is greater than the shear rate provided by another of the at least two high shear devices.
