Kraft lignin is a product of the sulfate pulping process. It usually contains 2–3% total sulfur. Sulfur content acts as deterrent to lignin use in some areas. Sulfur-free lignins are more versatile and can be heat-treated without the release of fou

The hydrolysis (or hydrolytic) lignin as a byproduct of ethanol production is made by the treatment of wood with a sulfuric acid solution. It contains up to 2% total sulfur. This work proposes the hydrolysis lignin desulfurization by acid–base meth

Black liquor soap is used to produce tall oil with subsequent fractionation. The main distilled products are tall oil rosin and fatty acids, as well as pitch. The presence of sulfur compounds in tall products limits the number of their end-use applic

Tall oil rosin has limited application due to the presence of sulfur compounds. By treatments with acetic acid and 2-ethoxyethanol the total sulfur content of tall oil rosin was reduced from 630 to 48 ppm.
