Conversion of the Rosin Acid Fraction of crude Tall Oil into Fuels and chemicals

摘要

Tall oil rosin acid, a forest product industry residue, has been converted into a diesel fuel additive in a single step process. Fractionating of crude tall oil produces an excess of rosin aids. This material is an abundant, inexpensive and chemically desirable feedstock. Two components, Abietic acid and dehydroabietic acid, comprise about 70/100 of the rosin acid fraction of tall oil.
