Jul 1, 2024 · A crucial step in creating pulp from lignocellulosic feedstock is pulping, which lays the groundwork for the later production of paper and associated goods. Pulping, a diverse process using chemical, mechanical, and/or biological means, extracts cellulose fibers from woody materials and separates them from lignin to make paper [ 99 , 119 , 120 ].

- Lignocellulosic Fiber
Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products .
Jun 19, 2018 · Currently, it is the main traditional method for pulping, producing the largest volume of lignin (Smook 2002) which is present as a low-MW fraction in the “black liquor” (alkaline liquid remaining after pulp extraction). The delignification process happens in three stages.

The first step to obtain nanocellulose by acid hydrolysis constitutes a number of processes, known as pulping and bleaching, that involves the isolation of fibers from the breakdown of cellulose-lignin-poliosis complex without the destruction of fibrils [22, 23].
Jul 26, 2023 · Kraft lignin, a by-product from the production of pulp, is currently incinerated in the recovery boiler during the chemical recovery cycle, generating valuable bioenergy and recycling inorganic chemicals to the pulping process operation.
