Transformations Catalytiques Des Hydrocarbures Aromatiques. I. Étude Thermodynamique du Processus de Disproportionation du Toluène

Abstract

AESTRACTToluene disproportionation based a chemical model by thermodynamic way was studied. The d i s t r i b u t i o n of reaction products was c a l c u l a t e d by computer(Fe1ix C-256). Disproportionation of toluene w a s a l s o c a r r i e d o u t using NaY z e o l i t e s as c a t a l y s t s , where t h e c a t i o n w a s exchanged with Lak, Cek, Co2+, Sr2+ ions and t h e composition of r e a c t i o n mixture w a s determinated by gas chromatograpby. A good agreement between t h e conversions c a l c u l a t e d by thermodynamic way and experimental data w a s noticed proving t h a t t h e discuSsed model can be applied.
