FIELD: chemistry.
SUBSTANCE: invention relates to a method for deoxygenation of tall oil and producing polymerised monomers. The method for producing polymerised monomers from tall oil has the following steps: introducing the sulfonated crude tall oil and hydrogen gas into the catalyst layer; catalytic deoxygenation of oil by hydrogen in the catalyst layer at a temperature of 280°C to 350°C using a sulfided metal catalyst; cooling the stream comimg out from the catalyst layer; separation of hydrocarbon liquid phase from the gas phase; steam cracking of the hydrocarbon liquid to obtain a product containing polymerisable olefins.
EFFECT: invention provides an improved yield of aliphatic and non-aromatic cyclic hydrocarbons at the deoxygenation stage, which leads to increased yield of subsequently polymerised monomers.
