Effect of Cellulases and Xylanases on Refining Process and Kraft Pulp Properties
PLOS ONE, 2016 Samples of bleached kraft pine cellulosic pulp, either treated with an enzyme preparation (a Thermomyces lanuginosus xylanase, an Aspergillus sp. cellulase, and a multienzyme preparation NS-22086 containing both these activities) or untreated, were refined in a laboratory PFI mill.

Optimising Energy Recovery in Hydrothermal Liquefaction of Radiata Pine and Kraft Mill Black Liquor
Chemical Engineering Transactions, 2018 The aim of this paper is to develop a heat exchanger network for hydrothermal liquefaction that is co-located with an existing Kraft pulp mill. Hydrothermal Liquefaction (HTL) is an energy-intensive process that operates at high temperature and pressure.

Experience in Use of GREENOXTM Process in Delignificatior of Kraft Pulps
JAPAN TAPPI JOURNAL, 2001 The aim of the present study was to examine the use of GREENOXTM process in bleaching of kraft pulps.The GREENOXTM process is a method to bleach kraft pulps with molybdate-activated hydrogen peroxide. This process is a delignification method that can be installed in existing bleaching plants without no larger investments required.Circulation of the ...

THE MANUFACTURE OF KRAFT PULP BY SODIUM HYDROXIDE PROCESS
Journal of the Japanese Technical Association of the Pulp and Paper Industry, 1949 It is pointed out that the pulp made by this process is quite suitable for making wrapping and bag paper as well as vulcanized fiber substitute, paper container etc. The preparation of cooking liquor is described and particularly, cooking operation and gas recovery are explained with experimental data. The following points are made clear 1) Composition

Kraft: An autonomous robot manipulation system based on geometrical modeling and processing.
Journal of the Robotics Society of Japan, 1989 This paper describes an autonomous robot manipulation system based on geometrical modeling and processing. We call it Kraft (Kobe Robot Arm Free from Teaching). Kraft plans the manipulator motion by the following sequence. Firstly, the model of the working environment is obtained interactively by a range finder and the geometric model of it.
