ABSTRACT: For enhancing the activity of Ni/TiO2-SAPO-11 catalyst,
SAPO-11, the precursor was prepared by hydrothermal crystallization, and TiO2-SAPO-11
complex carrier was prepared by sol-gel method, then Ni/TiO2-SAPO-11
was produced by the final product. The catalytic performance of Ni/TiO2-SAPO-11
was studied in n-heptane isomerization, and the impact of catalyst preparation conditions
on n-heptane isomerization was discussed in detail. The results showed that,
with 20% of TiO2 composition, 2% of Ni capacity percentage and calcined
temperature at 500°C, conversion of n-heptane and isomerization selectivity was
up to 40.94% and 88.97% respectively.
