20080286177 | Reactor with differentially distributed catalytic activity - A catalytic reactor in which higher catalytic activity is distributed proximate to the reactor wall than remote from the reactor wall to provide a greater heat source in the case of exothermic reactions or greater heat sink in the case of endothermic reactions proximate to the reactor wall to increase the temperature gradient and heat transfer between the reactor wall and the internal volume of the reactor. | 11-20-2008 |
20080299022 | PROCESS FOR PRODUCING LIQUID AND, OPTIONALLY, GASEOUS PRODUCTS FROM GASEOUS REACTANTS - An installation for producing liquid and, optionally, gaseous products from gaseous reactants. The installation has a reactor vessel having a vertically extending slurry bed zone; a first gas inlet in the vessel at a low level within the slurry bed zone for introducing gaseous reactants; a second gas inlet in the vessel at a level within the slurry bed zone which is above the first gas inlet for introducing recycled gas, the second gas inlet in the vessel being above the lower 20% of the vertical height of the slurry bed zone; a gas outlet in the vessel above the slurry bed zone, for withdrawing gas from a head space above the slurry bed zone and a liquid outlet in the vessel within the slurry bed zone, for withdrawing liquid product from the vessel. | 12-04-2008 |
20090035198 | HYDROCARBON CONVERSION UNIT INCLUDING A REACTION ZONE RECEIVING TRANSFERRED CATALYST - One exemplary embodiment can include an apparatus for transferring catalyst from a regeneration zone to a reaction zone in a hydrocarbon conversion unit. The hydrocarbon conversion unit can include a transfer vessel, and first, second, and third lines. The transfer vessel can transfer regenerated catalyst from the regeneration zone at a first pressure to the reaction zone at a second pressure where the second pressure is greater than the first pressure. Generally, the first line communicates the catalyst to the transfer vessel and is coupled to a first valve to allow catalyst into the transfer vessel and the second line communicates the catalyst from the transfer vessel and is coupled to a second valve to allow catalyst out of the transfer vessel. The third line for allowing the passage of gas therethrough may be at a pressure higher than the first pressure having a first portion communicating with the transfer vessel and having a second portion coupled to third and fourth valves. Each of the third and fourth valves can have a first position that is open and a second position that is closed, which may correspond, respectively, to the opening and closing of the first and second valves to allow gas to pass therethrough. | 02-05-2009 |
20090110616 | METHOD AND APPARATUS FOR IMPROVING RADIAL FLOW MOVING BED REGENERATION/REACTION SYSTEM PERFORMANCE - An improved radial or cross flow moving bed regenerator or reactor, in which the solid particle residence time in the vessels can be changed in different section of the regenerator or reactor. The improvement results from the placement of one or multiple screen inserts which divides the radial or cross flow bed into separate solid flow channels. The residence time of the solid in each solid flow channels are optimized based on the regeneration or reaction requirement by changing the location, orientation and geometry of the screen inserts. As a result of the optimization of solid residence time in different section in the radial flow bed, the efficiency of a regenerator or a reactor is improved. | 04-30-2009 |
20090155144 | Fluid Distributor for Radial-Flow Reactor - The distribution of fluids within a radial-flow reactor is improved using vertically extended cylinders distributed around the circumference of the vessel. Cylinders with a circular cross-section provide substantial vertical strength, and the configuration minimizes low-flow areas which could cause undesirable reactions. The cylinders are isolated from particles in the reactor by a particle-retaining outer conduit. The cylinders may be fabricated in panels for ease of installation and servicing. | 06-18-2009 |
20100209317 | Flexible Pressure Containing Shaped Coverplate Configuration - A flexible pressure containment coverplate has been invented for radial flow reactors. The coverplate is for a fixed bed reactor wherein the reactor undergoes significant thermal cycles. The coverplate provides flexibility for axial and radial thermal growth, while providing a sealing capability to prevent leakage of the fluid. The coverplate has a half toroidal structure, with a semi-circular cross-section. | 08-19-2010 |
20100316540 | FIXING DEVICE FOR CATALYZER PARTICLES - With the help of a fixing device for catalyzer particles, wherein the catalyzer particles are packed in a bed which can be passed through by a gas flow in the direction of gravity, it is intended to achieve a minimum specific pressure loss which will remain low even if dirt should arise from the operating process; a fixing device which has a minimum influence on the period of presence of the gas flowing through; which ensures the reliable hold-down of the catalyzer particles even at high approach velocities; and which is flexible to a certain degree in order to adapt to bed changes. | 12-16-2010 |

20110038764 | SCREENLESS REACTOR FOR GRANULAR MOVING BED - A screenless reactor design is presented. The reactor includes a series of overlapping vanes where solid catalyst can cascade down the vanes. Gas flows across the catalyst by flowing through the vanes contacting the catalyst and then disengaging from contact with the solid catalyst particles. | 02-17-2011 |

20150078970 | CATALYST RETAINER FOR RADIAL FLOW REACTOR - A catalyst retainer includes an inner particle retention device having apertures and a first non-apertured section; and an outer particle retention device having apertures and a second non-apertured section. The inner and the outer particle retention devices are spaced apart to define a particle retaining space of the retainer. The first non-apertured section and the second non-apertured section define a blanked-off section of the particle retaining space, and the blanked-off section is spaced from an end of the particle retaining space. The catalyst retainer also includes a louver with at least a portion located between the blanked-off section and the end of the particle retaining space. The louver extends into the particle retaining space at an angle with respect to an inner surface of the inner particle retention device. The louver introduces the fluid to the top catalyst free surface in a more uniform manner and hence prevents particle movement and attrition. | 03-19-2015 |
