    Abstract: The present invention discloses an in-line production method for providing a retention agent into a liquid flow of a stock suspension and into the short circulation of a paper making machine, wherein the method comprises the steps of: (i) providing a liquid flow of a stock suspension; and (ii) feeding at least one additive into said liquid flow of the stock suspension, wherein said retention agent is formed directly in said stock suspension. The at least one additive may be added to the stock suspension e.g. as a liquid flow. The retention agent provided by the method of the invention may further improve the control of the dewatering rate and subsequently the strength properties of the paper. By this method there is provided a way of forming a retention agent directly into the stock suspension. The need of transporting, e.g. a readymade solution of a retention agent is thereby abolished, and thus the retention aid may be formed in a very cost-efficient way. Further as the retention agent is formed directly into the stock suspension it may very quickly and efficiently adhere to the fine particles, or the filler in the stock suspension and thus a more efficient effect may be achieved.

    Abstract: The invention relates to a method of deoxygenation of tall oil as well as methods for the production of aliphatic hydrocarbons and polymerizable monomers from tall oil. Sulphurous crude tall oil (5) together with hydrogen gas (6) is fed into a reactor (1) comprising a catalyst bed (2, 3). The oil is catalytically deoxygenated by hydrogen in the bed by use of a sulfided metal catalyst, e.g. a Ni-MoS catalyst. The flow exiting the reactor is cooled down and a hydrocarbon-bearing liquid phase (10) is separated from a gas phase (18), followed by subjecting the liquid phase to distillation (14) for removal of useless aromatic hydrocarbons and then to steam cracking (4) to form a product containing olefins such as ethylene or propylene. By regulation of the deoxygenation temperature to be at least 270°C but less than 360°C the yield is rich in linear and cyclic aliphates that usefully turn to olefins in the steam cracking, while formation of napthalenes is reduced.
