C9 fraction

The main raw materials for сo-oligomers synthesis are waste and by-products of ethylene production, first of all ‒ a liquid pyrolysis products which contain aliphatic and aromatic hydrocarbons. The main part of these products is C9 fraction. Emulsion co-oligomerization of hydrocarbon fraction C9 allows for the maximum degree of processing liquid pyrolysis by-products, improve ecological production of ethylene, lower power inputs on the stage of the synthesis and release of co-oligomers compared to existing methods.

Improving the technology for producing cooligomers (syntheticlow molecular petroleum resins), which are obtained from chaep petrochemical raw materials – hydrocarbon fractions of liquid by-products of pyrolysis (LBPP) or cracking of oil, refining products or gas was discussed in the paper. The imperfections of industrial methods of initiated oligomerization are high reaction temperature , high reaction time, complexity of the selection of target products, high enough color.
