Organosolv pulping — methods and pulp properties
Biomass, 1987Abstract Potential benefits of using organic solvents for the delignification of lignocellulosic materials are discussed. Main characteristics of organosolv pulping methods published in the literature are presented and softwood pulp yields and strengths are compared with corresponding values of Kraft and sulphite pulps. Yields of organosolv softwood

Pulp depitching in the bisulfite pulping step
Russian Journal of Applied Chemistry, 2017OS-20 nonionic surfactant produced in Russia was used as a depitching additive in bisulfite pulping. OS-20 ensures efficient depitching of bisulfite pulp produced from various kinds of wood (spruce, aspen, birch wood or their blends). The strongest decrease in the total and “harmful” pitch content in pulping in the presence of the surfactant was ...

Pulp Anatomy and Characterization of Pulp Cells
2014Resident cells (stromal fibroblasts or pulpoblasts) including stem cells and nonresident pulp cells migrating from blood and bone marrow contribute to form the dental pulp population. Altogether they provide the extracellular matrix (ECM) proteins.
