Summary
-
1.
As the number of heteroatoms and functional groups in a resin molecule increases, its solubility in the fuel decreases.
-
2.
The quantity of fuel-insoluble resins increases as a result of the interaction of compounds of various molecular weights at the sites of free oxygen- and sulfur-containing functional groups, and also certain unsaturated bonds in the hydrocarbon groups of heteroatom compounds.
-
3.
When a fuel is in contact with oxygen, there is a marked increase in the amount of solid phase, which confirms the oxidative-condensation mechanism of the process.
-
4.
The formation of solid phase in a fuel can be limited or prevented by the use of additives.
