Abstract: The present invention relates to a method of manufacturing aromatic hydrocarbons, which are suitable for the production of terephthalic acid, from tall oil-based raw material. According to the invention, the raw material that contains tall oil or its fraction is catalytically deoxygenated with hydrogen, and one or more aromatic hydrocarbons (A) that can be converted into terephthalic acid are separated from the deoxygenated reaction yield (10). The deoxygenation catalyst is preferably a NiMo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The separated hydrocarbon is preferably p-xylene, o-xylene or p-cymene. According to the invention, these can be converted by oxidation and, when needed, by a re-arrangement reaction into terephthalic acid that is suitable for the source material of the manufacture of bio-based polyethylene terephthalate.

Abstract: Herein disclosed is biobased p-cymene, which can further be converted to terephtalate. Further, here is described a method for converting crude sulphate turpentine recovered from chemical wood pulping into p-cymene and eventually to terephtalic acid of biological origin, and and products thereof respectively. In said method, both conversion and desulphurisation is realised in one reaction step. Present disclosure is also related to use of zeolite catalysts in said method.

Abstract: The invention relates to a method of producing olefinic monomers for the production of a polymer. The invention particularly relates to the production of tall oil-based biopolymers, such as polyolefins. In the stages of the method bio oil, with a content of over 50% of fatty acids of tall oil and no more than 25% of resin acids of tall oil, and hydrogen gas are fed into a catalyst bed (7); the oil is catalytically deoxygenated in the bed by hydrogen; the flow exiting the bed is cooled down and divided into a hydrocarbon-bearing liquid phase (10) and a gas phase; and the hydrocarbon-bearing liquid (13) is subjected to steam cracking (4) to provide a product containing polymerizing olefins. The deoxygenation in the bed can be followed by a catalytic cracking or, with a suitable catalyst, the deoxygenation and cracking can be simultaneous. The separated hydrogen-bearing gas phase can be circulated in the process.

Abstract: The invention relates to a process for treating cellulosic fibres which process comprises mechanically pre-treating the fibres followed by treating the fibres with an enzyme and thereafter mixing the fibres with a solution comprising an alkali metal hydroxide followed by mechanically treating the fibres to form microfibrillated cellulose. In this way it is possible to produce MFC in an improved and energy efficient way.

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.
