  • Publication number: 20140106993
    Abstract: Systems and methods for processing glycerol into one or more products and uses thereof are provided. In one or more embodiments, a method for treating soil can include applying a partially oxidized reaction product to a soil. The partially oxidized reaction product can be prepared by decreasing a pH of a mixture that includes glycerol and fatty acids to produce a mixture that includes a glycerol-rich portion and a fatty acids-rich portion. The glycerol-rich portion can be reacted with at least one of an oxidant and a catalyst at conditions sufficient to produce the partially oxidized reaction product.

  • Patent number: 8519180
    Abstract: Systems and methods for processing glycerol into one or more products are provided. In at least one specific embodiment, the method can include decreasing a pH of a mixture comprising glycerol and fatty acids to produce an emulsion comprising a glycerol-rich portion and a fatty acids-rich portion. At least a portion of the glycerol-rich portion can be reacted with an acid comprising phosphorus at conditions sufficient to produce a reacted product comprising glycerophosphoric acid, glycerol, and a portion of the acid.
