| 20090088316 | Method for regenerating catalyst - An object is to efficiently separate catalyst grains from substantially inert grains and, optionally, separate a plurality of catalyst grains from one another, to thereby efficiently perform catalyst regeneration. After taking a catalyst-containing component containing a solid catalyst component deteriorated in a reaction, out of a fixed-bed reactor, the solid catalyst component is regenerated. If a plurality of components having different shapes from one another are contained as the solid catalyst components, after taking-out step, catalyst component separation step for separating such solid catalyst components from one another is performed and, then, the solid catalyst components are regenerated. Further, if an inert component is contained as the catalyst-containing component, after the taking-out step, an inert component separation step for separating the inert component is performed and then the solid catalyst component is regenerated. | 04-02-2009 |
| 20090099004 | CONTINUOUS PRODUCTION OF CARBON NANOMATERIALS USING A HIGH TEMPERATURE INDUCTIVELY COUPLED PLASMA - High-power inductively coupled plasma technology is used for thermal cracking and vaporization of continuously fed carbonaceous materials into elemental carbon, for reaction with separate and continuously fed metal catalysts inside a gas-phase high-temperature reactor system operating at or slightly below atmospheric pressures. In one particularly preferred embodiment, in-flight growth of carbon nanomaterials is initiated, continued, and controlled at high flow rates, enabling continuous collection and product removal via gas/solid filtration and separation methods, and/or liquid spray filtration and solid collection methods suitable for producing industrial-scale production quantities. In another embodiment, the reaction chamber and/or filtration/separation media include non-catalytic or catalytic metals to simultaneously or separately induce on-substrate synthesis and growth of carbon nanomaterials. The on-substrate grown carbon nanomaterials are produced in secondary chambers that are selectively isolated for periodic removal of the product. | 04-16-2009 |
| 20090163347 | Recovery of slurry unsupported catalyst - A method of recovering unsupported fine catalyst from heavy oil comprises combining a slurry comprising unsupported fine catalyst in heavy oil with solvent to form a combined slurry-solvent stream. The combined slurry-solvent stream is filtered in a deoiling zone. A stream comprising unsupported fine catalyst and solvent is recovered from the deoiling zone. Unsupported fine catalyst is separated from the stream comprising unsupported fine catalyst and solvent. Filtering in the deoiling zone can comprise filtering the slurry and solvent through a cross-flow microfiltration unit, recovering a retentate stream of the cross-flow microfiltration unit, combining the retentate stream of the cross-flow microfiltration unit with solvent to form a combined retentate-solvent stream, and filtering the combined retentate-solvent stream through a cross-flow microfiltration unit. | 06-25-2009 |
| 20100113253 | Microwave spent catalyst decoking method - The microwave spent catalyst decoking method is a method for regenerating petrochemical catalysts by removing coke deposited in the catalyst using a 2.45 GHz microwave oven. The spent catalyst is heated in air or pure oxygen in the presence of a susceptor. The susceptor is made of silicon carbide-based composite material that absorbs 2.45 GHz microwave energy fast and efficiently. In one embodiment, the susceptor material is formed into pellets that are preferably four to five millimeters in diameter. The susceptor pellets are mixed with the spent catalyst and loaded into a thermally shielded refractory tube that rotates about its central axis. In a another embodiment, the apparatus is a thermally shielded tower or vertical tube made of refractory material that is transparent to microwave radiation and supports rows of susceptor rods that are aligned horizontally. | 05-06-2010 |
