Compositions <strong>of</strong> Isomerization Products<br />
We compared the reactivity <strong>of</strong> two catalysts, one being zeolitic and the other amorphous. The<br />
activity <strong>of</strong> the zeolitic catalyst was higher than that <strong>of</strong> the amorphous type (Fig. 6).<br />

Activity <strong>of</strong> two kinds <strong>of</strong> catalyst<br />
Focusing on the relation between isomerization and cracking, we compared cracking ratios at the<br />
same isomerization ratio (Fig. 7). The amorphous catalyst had a lower cracking ratio in the low<br />
conversion region, but the zeolitic catalyst had a lower cracking ratio in the high conversion region.
