Sapaly, P. Mériaudeau, C. Naccache] n-octane has been hydroisomerised at 523 K on ZSM-12, 48 and 22, SAPO-5, 11, 31 and 41 containing Pt-Pd metal function. The materials were prepared with hydrothermal methods, and characterized. Selectivities to C8 isomers ranged from 99 to 50% maximum yield around 80% being reached on SAPO-11, 31 and 41, ZSM-22 and 48. Among the various C8 isomers 2-MeC7 was preferentially formed. Such selectivity was interpreted in terms of transition state shape selectivity at the pore mouths. To further corroborate these interpretations the reaction of 2-MeC7, 3-MeC7, 4-MeC7, 2,5-diMeC6, 2,2,4-TMP on the previous catalysts was also investigated. Determination of the respective reaction rates of these molecules, as well the product distribution analysis allowed to reinforce the concept of transition state shape selectivity at the pore mouths.
