Investigation of the fundamentals of fluorescent behavior of kraft-anthraquinone pulping liquors

Creator:

Perfecto Segoviano, Ignacio

Abstract:

The kraft and kraft-anthraquinone pulping processes were used for pulping Douglas-fir chips at 170°C, 180°C and 190°C temperatures. Anthraquinone was added to the pulping liquor at two levels, 0.1% and 0.2% based on wood, to study its effect on pulp delignification at the three temperatures. The fluorescent behaviors of kraft...

Interactions between dissolved wood organic chemicals and nonprocess elements in chemical pulping processes

Creator:

Wilson, Kenneth P.

Abstract:

This work is part of a larger project dealing with nonprocess element (NPE) behaviour in chemical pulping processes. Nonprocess elements are defined as those elements which are not essential to the chemical process, i.e. are neither active pulping chemicals (e.g., NaOH and Na2S in the kraft process), nor compounds present...
