Method of separating lignin derived compounds from pyrolysis oil

A novel method of separating bio oil (pyrolysis oil) into oxygenated rich species and lignin/phenolic based species in a highly efficient manner is provided. Lignin and phenolic fractions can be separated from light oxygenates from bio oil by use of reversible α-hydroxysulfonic acid.
