Course content
1st week History of paper and pulp production. Raw materials for the production of paper fibers. 2nd week Wood as a basic raw material for the production of pulp - its occurrence, properties, structure, composition. 3rd week Preparation of wood for the production of paper fibers - approach, storage, debarking, sorting of wood chips, organization of wood storage. 4th week Principles and technology of high-yield pulp production - pulp, pressure pulp, TMP, CTMP, CMP, BCTMP, APMP, XTMP. 5th week Effect of physical, supramolecular-chemical, chemical, biochemical, photochemical action on wood with the aim of producing paper pulp. 6th week Principles and technology of paper and chemical pulp production. Week 7 Chemistry of alkaline (sulphate), neutral (NSSC) and acid (acid sulphite) cooking processes 8th week Mechanism of delignification and hydrolysis reactions, selectivity and differences of multi-stage batches, kinetics of cooking processes, control of cooking processes. 9th week Modern brewing technologies - Super Batch, Energobatch, RDM, MCC, Organosolve processes. 10th week Pulp bleaching - chemistry. 11th week Technology of classic bleaching procedures based on chlorine compounds and modern procedures working with oxygen compounds. 12th week Washing, sorting, cleaning pulp. Regeneration of chemicals in pulp mills - sulfate and sulfite regeneration. 13th week By-products in pulp production. Environmental protection and occupational safety in pulp production. Properties of fibrous raw materials from the point of view of their use - evaluation of mechanical, chemical and optical properties of pulps, explanation of these properties.

Learning activities and teaching methods
Monologic (reading, lecture, briefing)
  • Contact teaching - 52 hours per semester
Learning outcomes
The basic knowlege of chemical pulping and the pulp properties. The students receive an ability to orientation in problems of both production and the properties of pulps.
The lectures are aimed at acquiring basic knowledge of the most important chemical processing of wood, i.e. the technology of pulp production and its properties as well as the properties of other fibers used in paper production.
Prerequisites
Předmět navazuje na základní znalosti z anorganické a organické technologie a chemie a morfologie dřeva.
