Process simulation of Kraft lignin oxidation for vanillin production

2023
Kraft lignin waste generated from Kraft pulping process can be potentially converted to a high value product such as vanillin. This work focused on feasibility study of vanillin production from Kraft lignin by oxidation reaction. A reaction model of Kraft lignin oxidation used in this work was selected from literature.

The Silicone Type Defoamers for Kraft Pulp Making Process

JAPAN TAPPI JOURNAL, 2001
In the kraft pulp making process, extracted lignin liquid (black liquor) contains various surfactive materials which are derived from lignin. That means black liquor tends to make foam so easily that the kraft pulp making process is troubled with foam at any time.

Electrolytic Processing of Kraft Black Liquor- Mass Transfer Investigation

ECS Meeting Abstracts, 2018
As an alternative to the chemical approach reducing the pH of black liquor to precipitate lignin using carbon dioxide and sulfuric acid, we have developed an electrochemical avenue for lowering pH while recovering caustic. It includes electrolytic treatment of black liquor that reduces its alkalinity to the critical point of lignin precipitation ...
