PROCESS FOR REMOVING WATER AND WATER SOLUBLE CONTAMINANTS FROM BIOFUELS

摘要

Water may be removed from a biofuel or biofuel intermediate by using a demulsifier. The demulsifier includes the product of oxyalkylating a resin prepared from a formulation including a phenol and a compound selected from the group consisting of an aldehyde, a diamine a polyamine and mixtures thereof. The demulsifier may also be used with admixtures of biofuels, biofuel intermediates, or biofuel feedstocks with conventional hydrocarbons.

1. A process for removing water from a biofuel selected from the group consisting of a biofuel, biofuel intermediate, a biofuel feedstock, and combinations thereof; wherein the process comprises:
admixing the biofuel with a demulsifier; wherein the demulsifier comprises a product formed from oxyalkylating a resin prepared from a formulation comprising a phenol and a compound selected from the group consisting of an aldehyde, a diamine, a polyamine, and mixtures thereof; wherein the biofuel has less than about 50 vol % of straight vegetable oil or straight waste vegetable oil.
