The production of a hydrocarbon resins (co-oligomers) by low-temperature dispersion co-oligomerization of C9 fraction of diesel fuel pyrolysis liquid by-products was researched. This method allows to reduce the temperature of the process. The synthesis was carried out by emulsion and suspension co-oligomerization. The main regularities of the suspension and emulsion oligomerization of the hydrocarbon fraction C9 are established. The effect of temperature, initiator concentration and process duration on the yield, physical and chemical properties of synthesized oligomers were investigated.
The synthesis of cooligomers by cooligomerization in the emulsion of hydrocarbon C9 fraction of liquid pyrolysis products is described. The major features of the cooligomerization of a mixture of unsaturated hydrocarbons of C9 fraction have been investigated and optimum process conditions have been selected. Одержано коолігомери за допомогою коолігомеризації в емульсії вуглеводневої фракції С9 рідких продуктів піролізу. Встановлено основні закономірності та вибрано оптимальні умови процесу коолігомеризації суміші ненасичених вуглеводнів фракції С9.
The experimental results concerning demulsified ability of block copolymers of ethylene and propylene oxides wich may be used as demulsifiers for oil emulsions have been represented. The dependence of their efficiency on the content of oxyethylene and oxypropylene groups in the molecule has been determined. The dependence of their degree of dehydration on the temperature and emulsion composition has been determined.
The investigated influence of surface tension on the process of emulsion cooligomerization. The synthesis of cooligomers by emulsion cooligomerization of hydrocarbon fraction C9 of liquid products of pyrolysis. The major features of the cooligomerization process of mixture of unsaturated hydrocarbons of fraction C9 have been investigated and optimum conditions have been selected.
