Abstract: The hydroisomerization and aromatization properties of a se-ries of different zeolite catalysts, primary Ni/HZSM-5，Ni/HFER, Ni/SAPO-11，Ni/Hpand Ni/HY were compared in a micro-reactor by using of n-octane as probing molecular. Re-sups show that Ni/HZSM-5 zeolite with the same pore structures
have the approximate product distribution, with the increase of Si/Al ratio, the liquid product yield and hydroisomerization se-lectivity have been improved. The large pore zeolite have more superior isomeric product selectivity than medium pore and small pore zeolite, the isomeric and aromatic selectivity of Ni/HY cat-alyst are 41. 83% and 3. 4% respectively. However, the Ni/
HZSM-5 catalyst with a higher Si/Al ratio has higher activity and excellent capability to retard the formation of coke, at the same time it has the optimum isomerization and aromatization performance.

Key words: zeolite, isomerization, aromatization, n-octane
