Comparative Evaluation of Additives in Softwood Fractionation: Impacts on Lignin Recovery and Pulp Quality. [PDF]
ChemSusChemChemical lignin stabilization during acid hydrotropic fractionation is shown to distinctly influence delignification, lignin quality, and pulp performance. Phenol enhances lignin removal, while thiol‐based modifier yields light‐colored lignin, high recovery, and strong pulp.

Pengaruh Suhu Sintesis Katalis Partikel Ceria Zirconia terhadap Efektivitas Proses Delignifikasi
Jurnal Teknik Kimia dan Lingkungan, 2020 Biomass is organic material produced through photosynthetic processes. The presence of lignin on the cell wall will inhibit cellulose to be converted into products. Delignification will open the lignocellulose structure to make cellulose more accessible.

Oxygen Delignification of Acid Sulfite and Bisulfite Softwood Pulps
BioResources, 2015 This study discusses alternatives for the production of sulfite pulps cooked to high kappa numbers, and a subsequent oxygen treatment by using the same cation in the cooking and in the oxygen stages. Magnesium was used as a cation during both the cooking
