摘要:
An alkylation catalyst having a zeolite catalyst component and a binder component providing mechanical support for the zeolite catalyst component is disclosed. The binder component is an ion-modified binder that can include metal ions selected from the group consisting of Co, Mn, Ti, Zr, V, Nb, K, Cs, Ga, B, P, Rb, Ag, Na, Cu, Mg, Fe, Mo, Ce, and combinations thereof. The metal ions reduce the number of acid sites on the zeolite catalyst component. The metal ions can range from 0.1 to 50 wt % based on the total weight of the ion-modified binder. Optionally, the ion-modified binder is present in amounts ranging from 1 to 80 wt % based on the total weight of the catalyst.

摘要:
We disclose an aromatization catalyst, prepared by a process comprising impregnating an L zeolite with platinum acetylacetonate. We also disclose a method of aromatizing a light naphtha, comprising reacting the light naphtha in the presence of an aromatization catalyst prepared by the process referred to above. The process of preparing the aromatization catalyst can also include loading the L zeolite with a Group IVB metal, a rare earth metal, or a lanthanide, such as titanium or thulium.

摘要:
Aspects of the present invention relate to an improved process for exchanging sodium ions in zeolites comprising sodium ions and rare earth metal ions for ammonium ions. For this exchange, aqueous solutions of ammonium salts, for example ammonium sulfate, ammonium nitrate or ammonium chloride, are currently being used. The resulting “ammonium zeolites” are calcined to convert them, with release of ammonia, to the H form of the zeolites suitable as a catalyst. The use of ammonium carbonate also minimizes the amount of rare earth metal ions which are leached out of the zeolites comprising rare earth metal ions.
