| Research Abstract |
Dealkylation of alkylnaphthalene proceeded on a mixture of macroporous aluminosilicate solid acid catalyst and MoO3/Al2O3. Where a silica monolayer supported by alumina was used as the solid acid, the selectivity was high. This finding can be applied to a new process for efficient conversion of the components difficult to decompose and use in heavy oils into diesel, gasoline and chemical resources. On the other hand, it was clarified by DFT calculations that the compressoion from both ends of SiOHAl made the acid strength. The compression was clarified to be due to the crystal structure. A strategy of design of acid site is obtained. The catalytic ability of silica monolayer can be related with the structure where SiOH groups arranged on the surface as compressed.
