Abstract: The invention discloses a method of producing a filler composition to be used in paper or board production, said method comprising providing a suspension comprising calcium hydroxide and performing carbonation of the calcium hydroxide to form precipitated calcium carbonate (PCC). The invention is characterized in that starch and/or carboxy methyl cellulose (CMC) is added to the suspension during said carbonation of calcium hydroxide. The method of the invention enables an increased filler content in paper or paperboard without substantially increasing the dusting tendency or decreasing the strength of the paper or board.

Abstract: A hydrophobically sized fibrous web layer, preparation of a fibrous web or a fiber-based coating, a multilayer board product having at least a middle layer formed of said fibrous web, as well as use of a heat-sensitive surfactant for said methods and products, whereby microfibrillated cellulose (MFC) and hydrophobic size are brought to a foam with water and the heat-sensitive surfactant, the foam is supplied to a forming fabric of a paper or board machine, dewatered by suction of air through the forming fabric, and dried to a web product. Alternatively the foam may be supplied onto a premade fibrous web and dried to form a coating layer. The hydrophilic functionality of the surfactant contained in the web may be destroyed by heating. Pulp of a greater fiber length, such as CTMP, may be included, to provide improved wet and dry tensile strength for the paper and board products.

Abstract: The present invention relates to a method of deoxygenating tall oil pitch, yielding aliphatic and aromatic hydrocarbons. The invention even comprises turning the aliphates into polymerizable olefins by steam cracking, and turning the aromates into polymerizable terephthalic acid by oxygenation and, as necessary, rearrangement. The monomers can be used for the production of polymers of partially or completely biologic origin. According to the invention, tall oil pitch is first heated to turn it into liquid, which is then fed into a catalyst bed and catalytically deoxygenated with hydrogen. The deoxygenation catalyst is preferably a Ni—Mo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The deoxygenated product stream is cooled down so as to obtain a liquid, which is distilled for separation of the aliphatic and aromatic hydrocarbons for use in the production of the respective monomers and finally polymers.
