20110313062 | SLURRY BUBBLE COLUMN REACTOR - A slurry bubble column reactor with a gas distribution arrangement comprising an upper sparger, a lower sparger, and an open-ended tube. Gas from the lower sparger enters the tube and lowers the density of slurry in the tube. The difference in slurry density causes the slurry in the tube to rise, causing slurry outside the tube to move down, maintaining circulation and flushing catalyst from the vessel wall. | 12-22-2011 |
20110313063 | APPARATUS AND METHOD FOR CONDUCTING A FISCHER-TROPSCH SYNTHESIS REACTION - A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production. | 12-22-2011 |
20120157555 | APPARATUS AND PROCESS FOR THREE-PHASE REACTION - A system and process for removing catalyst fines from a gas stream overhead the slurry in a Fischer-Tropsch slurry bubble column reactor. The gas phase at the top of the slurry bubble column reactor containing small amounts of entrained liquid and catalyst particles. The unreacted gases are passed through a demister, which removes larger droplets and catalyst particles. Smaller droplets and catalyst fines are conveyed to a secondary gas cleaner, such as a cyclone, whereby substantially all remaining particles are removed from the gas phase. A particle-containing liquid produced in the secondary gas cleaner can be further subjected to a filtrate cleaning unit to filter out fine catalyst particles and produce a substantially particle-free liquid product stream and a slurry stream of liquid product containing catalyst particles. | 06-21-2012 |

20080306316 | Process for Reacting an Aromatic Hydrocarbon in the Presence of Hydrogen - Processes comprising: providing a starting material comprising one or more aromatic hydrocarbons, and having an aromatic sulfur compound content and a total sulfur content; reducing the aromatic sulfur compound content and the total sulfur content in the starting material; and hydrogenating the one or more aromatic hydrocarbons in the presence of a supported ruthenium catalyst and hydrogen. | 12-11-2008 |
20090259083 | METHOD OF REGENERATING RUTHENIUM CATALYSTS FOR THE HYDROGENATION OF BENZENE - The present patent application describes a method of regenerating a ruthenium catalyst for the hydrogenation of benzene, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity has been attained. | 10-15-2009 |
20100286461 | PROCESS FOR CONTINUOUS HETEROGENEOUSLY CATALYZED PARTIAL DEHYDROGENATION OF AT LEAST ONE HYDROCARBON TO BE DEHYDROGENATED - A process for continuous heterogeneously catalyzed partial dehydrogenation of at least one hydrocarbon to be dehydrogenated in a reactor which is manufactured from a steel with specific elemental composition on its side in contact with the reaction gas, and also partial oxidations of the dehydrogenated hydrocarbon and the reactor itself. | 11-11-2010 |
20110009627 | REACTOR FOR CARRYING OUT HIGH PRESSURE REACTIONS, METHOD FOR STARTING AND METHOD FOR CARRYING OUT A REACTION - The invention relates to a reactor for performing high-pressure reactions, comprising at least one tube ( | 01-13-2011 |
20110038763 | PROCESS FOR CONTINUOUS HETEROGENEOUSLY CATALYZED PARTIAL DEHYDROGENATION OF AT LEAST ONE HYDROCARBON TO BE DEHYDROGENATED - A process for continuous heterogeneously catalyzed partial dehydrogenation of at least one hydrocarbon to be dehydrogenated in a reactor which is manufactured from a composite material which consists, on its side in contact with the reaction chamber, of a steel B with specific elemental composition which, on its side facing away from the reaction chamber, either directly or via an intermediate layer of copper, or of nickel, or of copper and nickel, is plated onto a steel A with specific elemental composition, and also partial oxidations of the dehydrogenated hydrocarbon and the reactor itself. | 02-17-2011 |

20110152576 | PROCESS FOR PREPARING CYCLIC KETONES - The present invention relates to a process for preparing at least one monocyclic ketone having from 4 to 20 carbon atoms by reacting a mixture G | 06-23-2011 |
20110196181 | PROCESS FOR REACTING AN AROMATIC HYDROCARBON IN THE PRESENCE OF HYDROGEN - Processes comprising: providing a starting material comprising one or more aromatic hydrocarbons, and having an aromatic sulfur compound content and a total sulfur content; reducing the aromatic sulfur compound content and the total sulfur content in the starting material; and hydrogenating the one or more aromatic hydrocarbons in the presence of a supported ruthenium catalyst and hydrogen. | 08-11-2011 |
20120157719 | TUBE BUNDLE REACTOR FOR UNCATALYZED OR HOMOGENEOUSLY CATALYZED REACTIONS - The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely. | 06-21-2012 |
