METHOD OF PRODUCING BIO-HYDROCARBONS BY THERMAL CRACKING OF ISOPARAFFINS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of producing bio-hydrocarbons. Method of producing bio-hydrocarbons includes: a step for providing an isomeric raw material obtained from a biologically renewable feedstock and containing C10-C20 hydrocarbons in an amount of more than 50 wt. %, preferably at least 75 wt. %, more preferably not less than 90 wt. %, the content of C10-C20 hydrocarbons with even number of atoms in the carbon chain preferably greater than 50 wt. %, and aromatic compounds in amount of not more than 1.0 % by weight, preferably not more than 0.5 % by weight, more preferably not more than 0.2 % by weight, and olefins in amount of less than 2.0 % by weight, preferably not more than 1.0 wt. %, more preferably not more than 0.5 % by weight, and a cracking step, on which thermal cracking of the isomeric raw material is carried out to obtain bio-hydrocarbons, wherein thermal cracking at the cracking step is carried out at a temperature at the outlet of the coil (TOC) of not higher than 825 °C.;EFFECT: technical result is obtaining in sufficient amount of hydrocarbons, which are used as monomers or precursors of monomers during production of polymers.;10 cl, 4 dwg, 5 tbl
