Förfarande för framställning av olefina monomerer |
摘要 |
<p>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.</p> |
