Abstract: A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.

Abstract: A process for contacting a feed stream comprising an oxygenate feedstock and an aromatic feedstock comprising toluene with a catalyst and recovering a product comprising para-xylene. The catalyst comprises an improved MFI zeolite comprising in the calcined and ion-exchanged form a SiO2/Al2O3 ratio of from about 50 to about 600 and having a distribution of framework aluminum sites characterized by an initial xylene selectivity of greater than 70% in the TM diagnostic test.
