Patent number: 7482497Abstract: Methods and systems for the synthesis of alcohol are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and solubility of olefins in water. The high shear device may allow for lower reaction temperatures and pressures and may also reduce reaction time. In an embodiment, a method of making an alcohol comprises introducing an olefin into a water stream to form a gas-liquid stream. The method further comprises flowing the gas-liquid stream through a high shear device so as to form a dispersion with gas bubbles having a mean diameter less than about 1 micron. In addition, the method comprises contacting the gas-liquid stream with a catalyst in a reactor to hydrate the olefin gas and form an alcohol.Type: GrantFiled: June 20, 2008Date of Patent: January 27, 2009Assignee: H R D CorporationInventors: Abbas Hassan, Ebrahim Bagherzadeh, Rayford G.
