  • Patent number: 7119245
    Abstract: Novel methods for synthesizing wholly un-supported, high-flow catalytic membranes consisting of 100% crystalline ZSM-22 crystals with no binder phase, having sufficient porosity to allow high Weight Hourly Space Velocities of feedstock to pass through without generating back pressure. The ZSM-22 membranes perform favorably to existing bulk ZSM-22 catalysts (e.g., via 1-butene conversion and selectivity). The method of membrane synthesis, based on Vapor Phase Transport, allows free-standing, binder-less membranes to be fabricated in varied geometries and sizes so that membranes can be tailor-made for particular geometries applications. The ZSM-22 precursor gel may be consolidated into a semi-cohesive body prior to vapor phase crystallization, for example, by uniaxial pressing. These crystalline membranes may be modified by ion exchange, pore ion exchange, framework exchange, synthesis modification techniques to incorporate other elements into the framework, such as K, H, Mg, Zn, V, Ga, and Pt.

After formation of the composite material, the porous organic ion exchanger can be removed from the composite material to obtain the macrostructures, either before or after the porous inorganic material is hydrothermally treated with a structure directing agent to convert at least a portion of such porous inorganic material to a crystalline molecular sieve composition. The resulting macrostructure is composed of particles of the crystalline molecular sieve composition.

  • Publication number: 20030012729
    Abstract: This invention relates to a new synthetic porous crystalline material, designated MCM-71, a method for its preparation and its use in catalytic conversion of organic compounds. The new crystalline material exhibits a distinctive X-ray diffraction pattern and has a unique 3-dimensional channel system comprising generally straight, highly elliptical channels, each of which is defined by 10-membered rings of tetrahedrally coordinated atoms, intersecting with sinusoidal channels, each of which is defined by 8-membered rings of tetrahedrally coordinated atoms.

  • Patent number: 6491875
    Abstract: A particulate catalyst is regenerated by upward transport in a combustor having an extended length and separated from combustion gases with a single stage of cyclones. The extended length combustor ends with a termination device arranged to tangentially discharge particulate catalyst and gases into an open disengaging vessel and to achieve a high separation efficiency. Initial high separation efficiency provided by the termination device permits a single downstream stage of cyclones to reduce particulate emissions to acceptable levels. The combination of the separation device and the extended combustor can accommodate changes in particulate densities in the extended combustor without inducing cyclone overload.

  • Patent number: 6471941
    Abstract: A new synthetic porous crystalline material, designated ITQ-13, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making ITQ-13 in its silicate and borosilicate forms in the presence of HF using hexamethonium dihydroxide as a directing agent and hydolyzed tetraethylorthosilicate as a silica source. Aluminum-containing ITQ-13 can be produced by Al exchange of the borosilicate material. ITQ-13 is useful as an acid catalyst and as an adsorbent.

  • Publication number: 20020088740
    Abstract: An apparatus for carrying out a multi-step process of converting hydrocarbon fuel to a substantially pure hydrogen gas feed includes a plurality of reaction zones arranged in a common reaction chamber. The multi-step process includes: providing a fuel to the fuel processor so that as the fuel reacts and forms the hydrogen rich gas, the intermediate gas products pass through each reaction zone as arranged in the reactor to produce the hydrogen rich gas.

  • Patent number: 6348144
    Abstract: A method for regenerating a hydrocarbon conversion catalyst wherein at least a portion of a halogen-containing compound is precombusted in a precombustion zone, and the catalyst is regenerated in the presence of the halogen. By precombusting the halogen-containing compound in a precombustion zone rather than in the regeneration zone, this invention decreases the risk of permanent catalyst deactivation and of costly equipment damage in the regeneration zone. This method is adaptable to many processes for the catalyst conversion of hydrocarbons in which deactivated catalyst particles are regenerated in a moving bed.
