| Abstract: | Catalytic pyrolysis process of n-C6 HM, over HZSM- 5 acidic zeolites and acidic zeolites with oxides mixed or modified zeolites have been studied.Acidity and Basicity of zeolites were measured by TPD, IRand probe reaction techniques. Experimental results showed that the activity of n-C4 and yield of alkene, especially C2H4, over acidic zeolites were higher than that of Basic zeolites.The HZSM-5 with SiO2/Al2O3=60 were the highest. The Fe-Cr-K okides mixed with HZSM - 5 zeolite exhibited excellent catalytic properties.The yield of C2H4 and alkene over such catalyst is 37% and 68. 9%, respectively, the reaction temperature lower 80K than that of CaO Al2O3 catalyst. |
