Improving the technology for producing co-oligomers (synthetic low molecular petroleum resins), which are obtained from cheap petrochemical raw materials hydrocarbon fractions of liquid pyrolysis products (LPP) or cracking of oil, refining products or gas was discussed in the paper.
It was proposed to conduct a co-oligomerization of unsaturated hydrocarbons of С9 fraction in two stages. At the first stage the co-oligomerization was implemented using the suspension method with a dosed supply of a benzoyl peroxide initiator. For maximizing the conversion of raw materials, at the second stage of the studies, the co-oligomerization was carried out in the solution of С9 fraction unreacted residues of the suspension process, enriched with dicyclopentadiene, followed by obtaining co-oligomers with higher colour indices. The optimal technological parameters of the fraction co-oligomerization process were selected. The main regularities of the process and the physico-chemical characteristics of the obtained co-oligomers were defined.
The proposed technology allows obtaining co-oligomers of different brands with the highest possible product yield (within 39.0 ... 41.0 % masses in terms of the fraction).
