A method for producing polymerizable olefinic monomers, in particular for production of tall oil based biopolymers such as polyolefins. The method consists of 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. The tall oil is catalytically deoxygenated and the flow exiting the bed are cooled and separated into a liquid and a gas phase. The liquid phase, containing hydrocarbons, is subjected to steam cracking to provide final product containing polymerizable olefins. The deoxygenation in the catalytic bed can be followed by a catalytic cracking within the same bed or, with a suitable catalyst, the deoxygenation and cracking can be done simultaneously.

L'invention porte sur un procédé pour la production de monomères oléfiniques polymérisables, en particulier pour la production de biopolymères à base de tallöl tels que des polyoléfines. Le procédé consiste à introduire dans un lit de catalyseur une bio-huile ayant une teneur de plus de 50 % en acide gras de tallöl et pas plus de 25 % d'acides résiniques de tallöl, et de l'hydrogène gazeux. Le tallöl est désoxygéné par voie catalytique et le flux sortant du lit est refroidi et séparé en une phase liquide et une phase gazeuse. La phase liquide, contenant des hydrocarbures, est soumise à un craquage à la vapeur d'eau pour obtenir un produit final contenant des oléfines polymérisables. La désoxygénation dans le lit catalytique peut être suivie par un craquage catalytique dans le même lit ou, avec un catalyseur approprié, la désoxygénation et le craquage peuvent être effectués simultanément.
