Evolution of Methyl Mercaptan in Its-Assisted Kraft Pulping Process

Cellulose
Abstract Pulp industry is one of the oldest and most large-scale chemical industries to realize biomass high-value utilization in the world. In pulp industry, it is perplexed researches and engineers that the kraft pulp yield is far from the cellulose and hemicellulose contents in biomass.

Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]

BioResources, 2012
Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...

Anti-scaling agents in kraft pulping

BioResources, 2007
Scale formation in the digester during kraft pulping represents a great problem in pulp mills. Scaling reduces pulping control and efficiency, increasing energy costs and leading to cleaning breakdowns, with subsequent losses in productivity.

CHARACTERIZATION AND PROPERTIES OF ION EXCHANGERS PRODUCED FROM LIGNIN PRECIPITATED AFTER PEROXYACID PULPING

BioResources, 2008
Pulping of bagasse by one-stage and three-stage peroxyacetic acid was carried out. Characterization of the precipitated lignin from the waste liquor of the pulping process was studied using infrared spec-troscopy.
