Catalyst with improved activity/selectivity for light naphtha aromatization
摘要:
In an embodiment, a method for making a catalyst, comprises: forming a mixture comprising a germanium source, an alkali metal source, an aluminum source, and a silica source, wherein the mixture has a pH; adjusting the pH of the mixture to a value of greater than or equal to 9.5; crystallizing and calcining the mixture to form a zeolite; depositing platinum on the zeolite; and calcining the zeolite to form the final catalyst. The final catalyst is non-acidic and has an aluminum content of less than or equal to 0.75 wt % based on the total weight of the final catalyst excluding any binder and extrusion aide and a Si:Al2 mole ratio of greater than or equal to 125.
