Surfactants as an Aid in The Kraft Pulping of Hardwood [PDF]
, 1977 Surfactants were used in the pulping of Kraft hardwood chips in an attempt to decrease cooking time while attaining ·the same Kappa Number. It was found that surfactants could not be used to decrease cooking time, but anthraquinone and nonylphenol could ...

Investigation of the fundamentals of fluorescent behavior of kraft-anthraquinone pulping liquors [PDF]
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 ...

A Study of the Feasibility of Using a Pulping Aid with Polysulfide Kraft Cooks [PDF]
, 1970 The purpose of this paper was to determine the feasibility of using a pulping aid with a polysulfide kraft cook. Since any change in an operation such as pulping must yield a product such that the quality is better or not appreciably reduced and at the ...

EFEITO DA QUALIDADE DA MADEIRA NO DESEMPENHO DA POLPAÇÃO KRAFT
Ciência Florestal, 2014 The aim of this study was to evaluate the wood quality in the kraft pulping performance under two different pulping conditions at two delignification degrees based on results for the yield, brightness, viscosity, and k/ kappa corrected index.
