Abstract
Methods and systems for the hydrogenation of aldehydes and/or ketones are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and solubility of the hydrogen-containing gas (e.g. H2 gas) in the aldehydes and/or ketones. The high shear device may allow for lower reaction temperatures and pressures and may also reduce hydrogenation time with existing catalysts.
Claims14
A method of hydrogenating an aldehyde or a ketone comprising:
- a) introducing a hydrogen-containing gas into an aldehyde or ketone stream to form a gas-liquid stream;
- b) 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;
- and
- c) contacting the gas-liquid stream with a catalyst in a reactor to hydrogenate the aldehyde or the ketone.
