Abstract:
The present invention relates in part to a lignin composition and a method of fabricating a lignin composition. The invention also relates in part to a method of using a lignin composition to adsorb onto a petrochemical oil comprising the steps of providing a solution of lignin in an alcohol, providing an oil on a liquid surface, contacting the oil with the solution of lignin in an alcohol, adsorbing the lignin to the oil, and removing the adsorbed oil from the surface of the liquid.
