Lignin is a remarkable natural polyphenol that provides trees with physical and (bio-)
chemical resistance, as well as the ability to reach considerable heights. Lignin is also …

Lignin is a highly abundant source of renewable carbon that can be considered as a
valuable sustainable source of biobased materials. By applying specific pretreatments and …

The physical properties of biochars contribute to their function as a tool for environmental
management. Their physical characteristics can be both directly and indirectly related to the …

Different structured activated carbons were prepared from macadamia nutshell by chemical
activation with potassium hydroxide and zinc chloride. The influence of process variables on …

Adsorption of phenol in aqueous phase onto activated carbons (ACs) having different
textural and surface properties has been considered. Six types of ACs were used: three …

Low‐cost renewable lignin has been used as a precursor to produce porous carbons.
However, to date, it has not been easy to obtain high surface area porous carbon without …

This review details the structure of lignin and curates information on the characteristics that
this polymer must have for each specific use. Lignin is a by-product of the pulp and paper …

Membrane technology allows the separation from the black liquor of different lignin fractions
with a specific molecular weight being able to be used in the synthesis of several high value …

Lignin-rich biomass (beech wood, pine bark, and oak bark) and four lignins were tested as
precursors to produce activated carbon (AC) via a two-step chemical activation with KOH …

Black liquor lignin obtained from pulp and paper industry was employed as the precursor for
preparing activated carbon by physical activation with steam. The preparation was carried …
