  • Patent number: 8603932
    Abstract: This invention is directed to hydrocracking catalysts and hydrocracking processes employing a magnesium aluminosilicate clay. The magnesium aluminosilicate clay has a characteristic 29Si NMR spectrum. The magnesium aluminosilicate clay is the product of a series of specific reaction steps. Briefly, the magnesium aluminosilicate clay employed in the catalyst and process of the present invention is made by combining a silicon component, an aluminum component, and a magnesium component, under aqueous conditions and at an acidic pH, to form a first reaction mixture and subsequently the pH of the first reaction mixture is adjusted to greater than about 7.5 to form a second reaction mixture. The second reaction mixture is allowed to react under conditions sufficient to form the magnesium aluminosilicate clay. The resulting magnesium aluminosilicate clay combines high surface area and activity for use in hydrocracking catalysts and processes.

The pore size of the sieves can be adjusted by ion exchanging M1 cations with a suitable amount of another species. Embodiments of the invention are useful for various adsorptive fluid separation processes, including pressure swing adsorption processes. For example, disclosed embodiments are useful for separating methane from air.

  • Publication number: 20130252802
    Abstract: A zeolite-containing fixed bed catalyst is formed by pre-shaping a mixture of a reactive aluminum-containing component and a matrix component into pre-shaped particles, and contacting the pre-shaped particles with a reactive liquid containing a silicate for a sufficient time and temperature to form an in-situ zeolite within the pre-shaped particles. The contacting of the pre-shaped particles and the liquid is achieved such that there is relative movement between the pre-shaped particles and the liquid.

  • Patent number: 8518242
    Abstract: Catalysts are disclosed comprising fibrous substrates having silica-containing fibers with diameters generally from about 1 to about 50 microns, which act effectively as “micro cylinders.” Such catalysts can dramatically improve physical surface area, for example per unit length of a reactor or reaction zone. At least a portion of the silica, originally present in the silica-containing fibers of a fibrous material used to form the fibrous substrate, is converted to a zeolite (e.g., having a SiO2/Al2O3 ratio of at least about 150) that remains deposited on these fibers. The fibrous substrates possess important properties, for example in terms of acidity, which are useful in hydroprocessing (e.g., hydrotreating or hydrocracking) applications.
