Pulping Catalysts from Lignin — The Diels-Alder Step

摘要: Certain anthraquinone (AQ) compounds can be used in existing kraft processes to increase pulping rates and pulp yields. Such catalysts could also the focus for an industry-wide evolution of from high low sulfur-free methodology. Catalytic holds promise addressing problems with plant bleach effluents by producing pulps that are more easily bleached than standard modifying cooking process reduce amount residual lignin present prior bleaching.1
