    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: The invention refers to a method for forming particles or droplets of at least one substance comprising the steps of providing a foamed medium, which foamed medium comprises said substance, and forming particles or droplets of said substance at least partly by electrostatic processing. The use of foamed medium in electrostatic processing enables higher production speeds and increases the evenness of a coating layer formed by electrospinning or electrospraying the particles or droplets on a substrate.

    Abstract: The invention relates to a method of treating chemical pulp fibers by a polymerizing hydroxy acid, the fibers thus obtained and the products refined from them. In the method, the hydroxy acid reacts with the reactive groups of the fibers in the presence of a catalyst, forming ester bonds. The following units of the same hydroxy acid are oligomerized and/or polymerized to these grafted acid residues. The fibers thus treated and the products refined thereof endure better processing stages that include drawing and stretching than untreated fibers.
