422219000 | And means loading contact material into, or unloading contact material from, reactor or means providing internal contact material reservoir | 8 |
20080253943 | Method for vapor phase catalytic oxidation - An object of the present invention is to provide a method for vapor phase catalytic oxidation which is almost free of variations in reaction states in respective reaction tubes of the fixed bed multi-tube heat-exchanger type reactor. | 10-16-2008 |
20090068073 | SYSTEM AND METHOD FOR CATALYST LOADING/MIXING - A catalyst loading system comprising: a vessel comprising at least one gas distribution nozzle at or near the bottom of the vessel, a top fluid distributor located at or near the top of the vessel, a catalyst inlet through which catalyst is introduced into the vessel, a first contact point at which catalyst introduced into the vessel first contacts the contents of the vessel, and a discharge outlet whereby catalyst exits the vessel. Methods of preparing catalyst slurry for introduction into a downstream reactor or in-situ activation within the vessel utilizing the catalyst loading system are also disclosed. | 03-12-2009 |
20090110617 | Radial Flow Reactor Design for High Volumetric Flows - A new radial flow reactor design is presented. The design includes a plurality of cylindrically shaped beds wherein the beds are sized to be nested one within another, and the beds are disposed within a housing. | 04-30-2009 |
20090142241 | SYSTEM AND PROCESS FOR THE SEPARATION OF SUSPENSIONS OF SPENT CATALYSTS AND HYDROCARBONS FORMED IN A FLUID CATALYTIC CRACKING UNIT WITH MULTIPLE ASCENDING FLOW REACTION TUBES - The present invention relates to a system for the separation of suspensions of spent catalysts and hydrocarbons formed in an FCC unit with multiple ascending flow reaction tubes, comprising interconnections between each of the ascending flow reaction tubes and the separator vessel, each interconnection also comprises two sections The outside sections of the separator vessel are inclined and are connected to a single vertical section, which penetrates into the interior of the separator vessel, and which has at its lower end an open device for draining the spent catalyst from the suspensions separated in this sector. In the same vertical section, at the end of its internal part at the separator vessel, a series of two sets of cyclones are installed, the first set containing cyclones without sealing legs, and the second set containing conventional cyclones of the first stage. | 06-04-2009 |
20090285732 | Optimized Counter-Current Flow Baffle - A new reactor design is presented for a counter-current flowing reactor. The reactor has a catalyst flowing down through the reactor, and over baffles. Gas is admitted under the baffles and flows up through the solid catalyst bed. The design includes slotted plates that extend from the bottom of the baffle in the reactor to a position near the catalyst outlet. The gas flows through the slotted plates and is directed up through the catalyst bed, while directing the flowing catalyst to the catalyst outlet ports. | 11-19-2009 |
20100080741 | Apparatus for Mixing Regenerated and Carbonized Catalyst - An apparatus for mixing regenerated and carbonized catalyst involves obstructing upward flow of catalyst by one or more baffles between a catalyst inlet and a feed distributor. Each catalyst stream may be passed to opposite sides of a riser. Baffles obstruct upward flow to effect mixing of regenerated and carbonized catalyst to obtain a more uniform temperature and catalyst mixture before contacting the feed. | 04-01-2010 |
20120237412 | DEVICE FOR UNLOADING CATALYST FROM A REACTOR VESSEL - A device and method for automatic unloading of particles from the vertical tubes of a chemical reactor automatically feeds a fish tape into the bottom of the vertical tube to contact and dislodge the particles and automatically retracts the fish tape to allow the particles to fall out of the tube. | 09-20-2012 |
20130202498 | Catalytic Reactor and Catalyst Structure - A reactor defines first and second flow channels within the reactor, the first flow channels and the second flow channels extending in parallel directions along at least the major part of their lengths. A removable non-structural catalyst insert is provided in those channels in which a reaction is to occur, the catalyst insert comprising a plurality of foils bonded together and which subdivide the flow channel into a multiplicity of flow sub-channels. At least one end portion of the catalyst insert is devoid of active catalytic material. The end portion that is devoid of active catalytic material suppresses the reaction in that part of the flow channel, and so reduces the requirement for any thermal transfer at that part of the flow channel. | 08-08-2013 |
