Abstract

Synergetic catalytic effect of molybdenium (Mo) and chromnium (Cr) ions on HZSM-5 support have been carried out. The catalyst of MoCr/HZSM-5 have been tested for iszomerization of n-hexane based on non-hydrogen reaction. The results showed that the catalytic synthesis by impregnating Mo and Cr on HZSM-5 support with the suitable amount ( Mo:10 %; Cr:3 %) did not change the basis structure of HZSM-5. The catalytic effect of Mo, Cr have been showed by catalytic testing results, for that the isoparaffin selectivity of MoCr/HZSM-5 is 46.5 % higher than in the case of Mo/HZSM-5 (43.56 %). The synergystic catalytic activity was clearly expressed by the dehydrogenation and hydrogenation role of Cr enhancing the stability of isomerization effect of Mo on MoCr/HZSM-5 catalyst for n-hexane’s isomerization reaction. Research results could be considered as the scienctific basis results for catalytic research applied to gasoline high quality production from the condensate feed by non-hydrogen technology in Vietnam.
