Lignins are now considered as the main aromatic renewable resource. They represent an
excellent alternative feedstock for the elaboration of chemicals and polymers. Lignin is a …

Lignin is a complex organic polymer found in the plant cell wall with important biological
functions, such as water transport, mechanical support, and resistance to various stresses. It …

Technical lignins are bulk feedstocks. They are generated as byproducts from pulping or
cellulosic ethanol production. As lignin undergoes significant structural changes as a result …

Lignin is a highly abundant biopolymer with a complex polyphenolic structure, making it a
potential source of aromatic precursors, polymers, and energy. However, its thermal stability …

The use of plant biomass as starting material is one of the alternatives to reduce the
dependency on fossil oil for transportation fuels and is the main alternative to replace …

A softwood Kraft black liquor was acidified with carbon dioxide at 115° C and 6.2 bar over a
pH range of 13.6–9.5, resulting in the precipitation of liquefied-lignin fractions as a separate …

CO2 acidification of Kraft black liquors was performed at temperatures of 100–150° C and
pressures of 5–8 bar in an investigation of the SLRPTM process. At these conditions, a …
