Abstract: Provided here are nano-sized mesoporous zeolite compositions and the methods of synthesis and use of these compositions. These nano-sized mesoporous zeolite compositions are synthesized from a mixture of silicon source and an aluminum source fumed or colloidal silica with aluminum powder or aluminum oxide. Also provided are methods for hydrocracking a hydrocarbon feedstock by using catalysts containing the nano-sized mesoporous zeolite composition.

Abstract: According to one or more embodiments disclosed herein, a mesoporous zeolite may be made by a method comprising contacting an initial zeolite material with ammonium hexafluorosilicate to modify the framework of the initial zeolite material, and forming mesopores in the framework-modified zeolite material. The contacting may form a framework-modified zeolite material. The mesoporous zeolites may be incorporated into catalysts.

Abstract: Described here are various processes for producing linear alpha olefins using a heterogeneous catalytic composition in the reaction mixture. These processes include size-based or phase-based separation of the heterogeneous catalytic compositions from the product stream and recycling the catalysts to the reaction mixture. Various other embodiments may be disclosed and claimed.

Abstract: According to one embodiment, a heavy oil may be processed by a method that may include upgrading at least a portion of the heavy oil to form an upgraded oil, where the upgrading comprising contacting the heavy oil with a hydrodemetalization catalyst, a transition catalyst, a hydrodenitrogenation catalyst, a first hydrocracking catalyst, and a second hydrocracking catalyst downstream of the first hydrocracking catalyst to remove at least a portion of metals, nitrogen, or aromatics content from the heavy oil and form the upgraded oil. The final boiling point of the upgraded oil may be less than or equal to 540° C. The second hydrocracking catalyst cracks at least a portion of vacuum gas oil in the heavy oil. The first hydrocracking catalyst may comprise a greater average pore size than the second hydrocracking catalyst.
