Conclusions
-
1.
An increase in the temperature of the aromatization of propylene and isobutylene in the presence of aluminum oxide from 300 to 625°C is accompanied by an increase in the conversion of the original olefins; appreciable formation of aromatic hydrocarbons occurs only above 500°C. The greatest selectivity with respect to aromatic hydrocarbons is achieved at 550–625°C.
-
2.
An increase in contact time is accompanied by a significant increase in the conversion of the original olefins, but does not exhibit an appreciable influence on the composition of the liquid reaction products nor on the selectivity with respect to aromatization.
