Abstract:

A method for making catalyst materials is disclosed in which active metal ingredients of the final catalyst are added to a mixture for extruding the catalyst material that includes a binder, one or more precursors of one or more base metals and/or one or more noble metals, and a crystal of a zeolite. The extruded catalyst material is then pre-calcined and ion-exchanged and then a final calcining step is applied. The catalyst materials made by such a method are also disclosed as is a method for treating a hydrocarbon stream using the catalysts.

Abstract:

Methods, catalysts, and corresponding catalyst precursors are provided for performing dewaxing of diesel or distillate boiling range fractions. The dewaxing methods, catalysts, and/or catalyst precursors can allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. The catalysts and/or catalyst precursors can correspond to supported metal catalysts and/or catalyst precursors that include at least one noble metal, such as Pt, at least one Group 8-10 base metal, preferably a non-noble Group 8-10 base metal, such as Ni and/or Co along with a Group 6 metal, such as Mo and/or W as supported metals along. The support can include a zeolitic framework structure. The catalyst precursors can be formed, for example, by impregnating a support including a zeolitic framework structure with impregnation solution(s) that also includes a dispersion agent.

Abstract:

Methods for regenerating and/or rejuvenating catalysts, particularly dewaxing catalysts, as well as methods for performing dewaxing of diesel or distillate boiling range feeds with the regenerated and/or rejuvenated catalyst are provided herein. The regeneration and/or rejuvenation methods can include calcining spent catalyst followed by contacting the calcined catalyst with a solution comprising a complexing agent, which can restore hydrotreatment (HDT) activity and dewaxing activity of the spent catalyst such that it may be reused during hydroprocessing.

The catalysts and/or catalyst precursors can correspond to supported base metal catalysts and/or catalyst precursors that include at least two Group 8-10 base metals supported on the catalyst, such as a catalyst/catalyst precursor including both Ni and Co as supported metals along with a Group 6 metal (i.e., Mo and/or W). The support can correspond to a support including a zeolitic framework structure. The catalyst precursors can be formed, for example, by impregnating a support including a zeolitic framework structure with an impregnation solution that also includes a dispersion agent.

Abstract:

Processes for forming refined hydrocarbons are disclosed. Exemplary processes include providing a first mixture comprising ≧10 wt % of at least one oxygenate; contacting at least a portion of the first mixture with a methanol conversion catalyst under suitable conditions including a first pressure, P, to yield an intermediate composition including olefins having at least two carbon atoms; introducing at least a portion of the intermediate composition to an oligomerization catalyst under suitable conditions including a second pressure, P, to yield an effluent mixture comprising gasoline boiling range components and distillate boiling range components; and recovering at least a portion of the gasoline boiling range components and distillate boiling range components. The first and second pressure can be relatively similar. Apparatus and systems for carrying out the disclosed processes are also described.
