| The impact of the Mg- and K-oxides is expected to depend on their dispersion, basicity, and their ability to ion exchange with the HY zeolite. The amount of Mg and K added to theMo2C/HY was well below the ion exchange capacity of the HY. Clearly, some K was exchanged with the acid sites of the HY support during preparation, but this did not occur in the case of Mg. |
