Abstract. Samples of kenaf (Hibiscus cannabinus) grown in Malaysia were examined to determine the kraft pulp and papermaking properties of their bast (or bark) kraft pulping process showed that bast fibers were relatively easy to cook resulting good pulp yields in the range of 45–51%.Cited by: History • Soda pulping process patented, • Soda recovery via incineration patented, • First successful soda mill, • Kraft pulping process patented by Dahl, • First commercially viable kraft mill, Sweden, • Kraft recovery furnace, ’ Size: 2MB.

The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibers, the main component of paper. The kraft process entails treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, .
1 CHEMICAL REACTIONS IN KRAFT PULPING IN COOKING The main objective is to facilitate the disintegration of wood into fibrous product. This is achieved by breaking the bonds in the lignin macromolecule. The main chemical reactions in the cooking process can be described as: NaOH + NaS 2 + Wood à Na-org. + S-org. + NaHSFile Size: KB. Part of the industrial process used to convert wood chips into pulp for use in paper and other cellulosic products, is the kraft pulping process. During the pulping process the wood components are released from the wood or converted into the useful by-products of methanol, turpentine, and tall oil.

Kraft Pulping [Jim Atkins] on *FREE* shipping on qualifying offers. Kraft PulpingManufacturer: TAPPI PRESS. The Kraft Pulping (and Bleaching!) Course The science and technology of kraft pulp-making and bleaching in a short, professional course for engineers, operators, and others providing a unique and intimate blend of knowledge, experience, and professional judgment the most effective way to rapidly understand the process and the mills.
Kocurek says, "The Introduction to Kraft Pulping and Bleaching Course is the kind of training that offers a view of 1996 Kraft pulping short course book entire puzzle, so to speak, rather than a detailed focus on one or two operations.
There are few if any other courses that combine this field of focus into one. Paperbase International,Abstract ) Sulphite pulp that is bleached without using chlorine, using oxygen and peroxide, turns yellow even with a kappa number as low as 4 to 8, whereas kraft pulp does not have this tendency.

Kraft Pulping and Characterization of Strength Properties of Fungal Treated and Untreated Bamboo Pulps Introduction Kraft pulping is one of the major chemical pulping processes used for production of pulp from complex wood based raw materials (Grace and File Size: KB.
For every ton of pulp produced, the kraft pulping process produces about 10 tons of weak black liquor or about tons of black liquor dry solids that need to be processed. The Kraft digester has two products - pulp and black liquor. Approximately 50% of the log that enters a Kraft mill goes to the Kraft recovery boiler as black liquor.

pulp capacity and about 55% of the total wood pulp capacity in this area are in kraft mills. About half of the kraft pulps are made into bleached or semibleaehed products.
The major reasons for the success Of the kraft pulping process can be summarized as follows: t. An efficient and recovery process has been developed for the pulping chemicals.
Size: 2MB. Kraft pulp Technologies for every major pulping, recovery, and power process. The major challenges facing pulp producers are to achieve steady-state production of uniform pulp quality with the lowest possible consumption of chemicals and water at the highest efficiency.
And to do this within tight environmental regulations. The Kraft Pulping Short Course provides participants with a variety of activities and learning environments. Team exercises using an actual mill problem and typical mill data offer participants an opportunity to learn how other mill people solve problems while picking up tips that might prove valuable in their own mills.

W.G. Glasser, in Encyclopedia of Materials: Science and Technology, Kraft or Thiolignins. The more modern kraft pulping process dissolves lignin from wood in aqueous mixtures of NaOH and Na 2 S. This treatment involves both derivatization (with the formation of thiol-groups) and molecular degradation (depolymerization) where the latter predominates.
