  • Publication number: 20110270006
    Abstract: A method is disclosed of preparing a catalyst, including contacting a substrate with at least one solution including a first promoter being Cs and at least one solution including a second promoter. The contact subjects the substrate to the addition of the first and second promoters, thereby forming the catalyst comprising the first and second promoters. In the method disclosed, the second promoter is capable of undergoing a redox reaction.

  • Publication number: 20110270007
    Abstract: 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.

  • Publication number: 20110257453
    Abstract: A method for the oxidative coupling of hydrocarbons includes providing an oxidative catalyst inside a reactor and carrying out the oxidative coupling reaction under a set of reaction conditions. The reactor surfaces that contact the reactants and products do not provide a significant detrimental catalyzing effect. In an embodiment the reactor contains an inert lining or a portion of the reactor inner surface is treated to reduce the detrimental catalytic effects. In an embodiment the reactor contains a lining that includes an oxidative catalyst.
