Abstract
Hydrocracking of isooctane catalyzed by the 12.5wt% MoO3-Al2O3 catalyst has been investigated at a hydrogen pressure of 50 atm, in the temperature range from 350 to 400°C. Cracking to isobutane and demethylation proceed on the catalyst reduced by H2. It is shown that both 2, 2-dimethylpentane and 2, 4-dimethylpentane are produced by demethylation. By sulfurization of the catalyst with 10%H2S-H2, the extent of cracking increases and that of demethylation decreases. It is also shown that only 2, 4-dimethylpentane is produced by demethylation on the sulfided catalyst. The reaction mechanism is discussed from the view point of the selectivity for the reaction and acidic properties of the catalyst. The reactions over the 3.5wt% CoO-12.5-wt%MoO3-Al2O3 and 3.5wt%CoO-Al2O3 catalysts have also been investigated under the same conditions.
