| Abstract: |
| The catalyst behavior of Fe2 ( S04 )3( NiS04 )/7?AI203 in isobutene oligomerization was studied. Effects of calcination temperature, loading of active constitute, ?(Fe)/?(Fe + Ni) and shape of catalyst were examined. It is shown that the catalyst with n( Fe)/n( Fe + Ni) being 0.67 shows the maximum catalytic activity. As calcined at 500 X,，the catalyst with loading of active constitute being 7 % exhibits the best catalytic performance in isobutene oligomerization. After the catalyst is shaped, its activity reduces by about 6%，but the selectivity of the target product (dimmer) increases by about 8% , and the total selectivity of dimmer and three polymerization product changes a little. |
