Abstract
Solutions of hydrated reversed micelles and mixtures of distillate cracking residue and light catalytic gas oil are studied by the methods of correlation spectroscopy of scattered light and polarized fluorescence, respectively. The temperature dependences of the particle size of the disperse phase are obtained. It is found that the particle size increases with temperature in the range from room temperature to the critical temperature, which depends on the composition of the system under investigation, at temperatures above the critical temperature, the particle size decreases. These dependences can be explained by the formation of clusters from particles of the disperse phase at temperatures below the critical temperature and subsequent destruction of these clusters. Therefore, the structures of model (micellar) and natural (oil) disperse systems are compared for the first time, and the correlation between their behavior upon heating is revealed.
