petroleum resin

It has been studied the production of petroleum resins by low-temperature inverse emulsion oligomerization of C9 fraction of diesel fuel pyrolysis liquid by-products. It is established that the determining factors of the C9 fraction of the inverse emulsion oligomerization are the following: reaction time, emulsifier concentration and phase ratio.  Yield and physicochemical characteristics of oligomers сorrelations were established.

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 process of tar and industrial petroleum resin “Piroplast-2” joint oxidation has been investigated. The experimental results of the main regularities researches of the obtaining process of petroleum resins with carboxyl groups based on the pyrocondensate C9 fraction of hydrocarbon feedstock pyrolysis have been shown. It has been established that synthesized petroleum resins may be used for the modification of petroleum bitumens.

Experimental results concerning main regularities of paraffin tar and petroleum resins joint oxidation are presented. It has been shown that petroleum resin in the amount of 5 mas % as raw material component allows to intensify oxidation and improve operational characteristics of obtained bitumen.

The tar oxidation process has been studied at 523 K, air flow rate of 2.0; 2.5 and 5.0 h-1 and process time of 6, 9 and 12 h in the presence of 2.5; 5.0 and 7.5 mas % (to calculate for the raw material)of petroleum resin with fluorine atoms. The tar is the residue of black oil vacuum distillation obtained from the oils of Western-Ukrainian fields. The effect of process conditions on the characteristics of obtained bitumen has been determined. The structural-group composition of blown bitumen has been examined.

The work deals with the cooligimerization of C9 fraction unsaturated hydrocarbons of pyrolysis liquid products (PLP) obtained during ethylene production from diesel fuel. The main regularities of coologomerization initiated by peroxides have been determined, the influence of the main factors (temperature, process time, initiators nature and concentration) on the yield and physico-chemical characteristics of the obtained cooligomers have been examined. The effective initiator of cooligomerization and optimal techno logical parameters of the process have been chosen.

Initiated by organic peroxides cooligomerization of unsaturated compounds of C5 fraction has been studied. Such fraction is a by-product obtained at ethylene production via hydrocarbon raw material pyrolysis. The main regularities of the process have been established, the effect of main factors (temperature, reaction time, nature and concentration of the initiators) on the yield and physico-chemical characteristics of the obtained cooligomers has been examined. The effective initiator and optimal technological parameters of the cooligomerization process have been determined
