    Abstract: The invention relates to a method for isolating xylan from plant material. In the method, cellulose fibres which contain xylan are used, advantageously cellulose fibres from hardwood; and xylan is extracted (20) from said cellulose fibres by means of sodium hydroxide for forming an extract solution (17) that contains xylan; cellulose fibres are removed from said mixture that contains cellulose fibres and extract solution (17), for isolating said extract solution from said mixture; carbon dioxide (14) is added to said extract solution (17) for isolating xylan, wherein liquid brightener (18) and precipitated xylan (12) are formed; calcium hydroxide (16) is added to said isolated brightener (18), for forming precipitated calcium carbonate and liquid sodium hydroxide (15); and sodium hydroxide is removed from said mixture that contains sodium hydroxide and precipitated calcium carbonate, for isolating calcium carbonate from said mixture. Furthermore, the invention relates to a system for isolating xylan from plant material, and to xylan, calcium carbonate, cellulose fibre and use of xylan.

    Abstract: The invention relates to a method for manufacturing paper pulp (10), in which method bleached, chemically pulped cellulose fibres (1) from hardwood are used as raw material. The method comprises extracting (5) xylan from said cellulose fibres (1) by means of sodium hydroxide; adding carbon dioxide into a mixture (2) containing said cellulose fibres (1), dissolved xylan and sodium hydroxide, for precipitating xylan; adding calcium hydroxide into said mixture containing precipitated xylan and cellulose fibres, for forming precipitated calcium carbonate (7); and removing sodium hydroxide from said mixture (4) containing sodium hydroxide, xylan, cellulose fibres (1), and calcium carbonate. Furthermore, the invention relates to paper pulp made by the method.
