Due to current attitudes arid regulations concerning the odorous emission of mercaptans from the Kraft pulping process, new technology must be developed to enable the process to be run at lower sulfide levels. The use of cyclic-keto compounds, as pulping catalyst, could be a major step in the reduction of sulfide levels in Kraft pulping, while acting to increase the pulping yield through a mechanism that stabilizes the carbohydrates during the process and catalyzes delignification.

The objective of this research project is to evaluate the performance of one cyclic keto compound that has recently received the attention of many researchers of anthraquinone.
