Abstract: A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.

Abstract: A catalyst composite and a process for preparing the catalyst composite are described. The catalyst composite includes a microporous material having a gallium component dispersed thereon; and a hydroxy metal oxide binder, where the metal is zirconium, titanium, or a mixture thereof. The process includes mixing a gelling agent, water, and the hydroxy metal oxide binder precursor to form a solution. The solution is combined with a microporous material to form a slurry, and the slurry is formed into a shaped article. The article is dried to convert the hydroxy metal oxide binder precursor into a hydroxy metal oxide binder and form the catalyst composite.

Abstract: Aluminas with increased surface acidity, methods of making the same, and methods for using the same are provided. In an exemplary embodiment, a method for increasing the surface acidity of an alumina material includes providing an alumina starting material, and processing the alumina starting material under hydrothermal conditions in the presence of one or more organic acids to generate a hydrothermally treated alumina. In this embodiment, the one or more organic acids includes a polyprotic organic acid with a pKa value of about 0 to about 10, and the resulting hydrothermally treated alumina has increased surface acidity relative to the alumina starting material.

Abstract: Composites of a crystalline or long-ranged ordered material (CLROM), for example zeolites and non-zeolitic molecular sieves, are disclosed. The composites have both a macroscopic particle size (e.g., an average particle size of greater than about 0.1 mm), as desired in commercial applications, as well as improved functionality. Such composites result from the conversion of a conventional amorphous material, for example a solid amorphous silica alumina of this particle size, into the CLROM. According to particular embodiments, all or substantially all (e.g., at least about 99%) of the amorphous material is converted to the CLROM, such that essentially the entire macroscopic material may have the desired functionality of the CLROM as a catalyst or adsorbent.

Abstract: A process for forming a zeolite beta dielectric layer onto a substrate such as a silicon wafer has been developed. The zeolite beta is characterized in that it has an aluminum concentration from about 0.1 to about 2.0 wt. %, and has crystallites from about 5 to about 40 nanometers. The process involves first dealuminating a starting zeolite beta, then preparing a slurry of the dealuminated zeolite beta followed by coating a substrate, e.g. silicon wafer with the slurry, heating to form a zeolite beta film and treating the zeolite beta with a silylating agent.
