Method of producing lower alcohols from glycerol

Image Number 15 for United States Patent #8252961.

This invention relates generally to a process for value-added processing of fats and oils to yield glycerol and glycerol derivatives. More particularly, the process converts glycerol to acetol and then acetol to propylene glycol to produce a propylene glycol with ultra-low amounts of ethylene glycol. The propylene glycol thus produced may be used as an antifreeze, deicing compound, or anti-icing compound.
