摘要: The present disclosure provides methods for producing a regenerated hydrogenation catalyst from a fouled hydrogenation catalyst having a total surface area and at least one associated impurity. The method can include maintaining contact between the fouled hydrogenation catalyst and a flushing medium that comprises water, oxygen, and an inert or diluent gas at a regeneration temperature and a regeneration pressure sufficient to remove at least a portion of the at least one impurity from the hydrogenation catalyst to produce the regenerated hydrogenation catalyst, where the regenerated hydrogenation catalyst is characterized as retaining at least 70% of the activity of the hydrogenation catalyst.

摘要: A method for processing a chemical stream includes contacting a feed stream with a catalyst in a reactor portion of a reactor system that includes a reactor portion and a catalyst processing portion. The catalyst includes platinum, gallium, or both and contacting the feed stream with the catalyst causes a reaction which forms an effluent stream. The method includes separating the effluent stream from the catalyst, passing the catalyst to the catalyst processing portion, and processing the catalyst in the catalyst processing portion. Processing the catalyst includes passing the catalyst to a combustor, combusting a supplemental fuel in the combustor to heat the catalyst, treating the heated catalyst with an oxygen-containing gas to produce a reactivated catalyst, and passing the reactivated catalyst from the catalyst processing portion to the reactor portion. The supplemental fuel may include a molar ratio of hydrogen to other combustible fuels of at least 1:1.

摘要: A fluidized catalytic reactor system cycles from 0.05-5% of catalyst at a time through a rejuvenation unit to be heated in the presence of oxygen to maintain catalyst activity. The use of the rejuvenation unit that may be 2% of the size of the main catalyst regeneration unit allows for reduction in equipment size and in catalyst inventory. The catalyst that is sent to the rejuvenation unit may be spent catalyst but may be partially or fully regenerated catalyst. The rejuvenation unit may be heated by combusting fuel or by hot flue gas.

摘要: An integrated process for producing C3-C4 olefins or di-olefins including: contacting a hydrocarbon feed and a catalyst feed in a fluidized dehydrogenation reactor under conditions such that a product mixture is formed and the catalyst is at least partially deactivated; transferring the product mixture and the catalyst from the reactor to a cyclonic separation system under conditions such that the product mixture is converted to form a new product mixture and is separated from the catalyst; transferring at least a portion of the catalyst to a regenerator vessel and heating it in order to combust the coke deposited thereon; subjecting the catalyst to a conditioning step to form an oxygen-containing, at least partially reactivated catalyst; and transferring the partially reactivated catalyst back to the fluidized dehydrogenation reactor.

Sulfur compounds are stripped from the spent catalyst and the catalyst is cooled before the regeneration process. The process includes controlling the amount of sulfur that needs to be removed from the catalyst before regeneration.

摘要: An exhaust gas purification device is equipped with: an NOx purification unit disposed in exhaust gas piping of an engine supporting an NOx storage catalyst (NSC); a catalyzed soot filter (CSF) disposed downstream of the NOx purification unit supporting a particulate combustion catalyst causing captured particulates to combust; and an electronic control unit (ECU) which controls exhaust gas flowing into the NSC to be rich and which, by raising the temperature of the NSC, acts as a regeneration device that causes sulfur components captured in the NSC to be desorbed. The particulate combustion catalyst is provided where Ag and Pd have been alloyed on an Al2O3 carrier; the quantity of Ag supported by the Al2O3 carrier is 1.2-2.5 g/L; the quantity of Pd supported by the Al2O3 carrier is 0.7 g/L or less; and the ratio Ag/Pd of the Ag support quantity to the Pd support quantity is 1.7-8.3.

摘要: A catalyst comprising a Group IIIA metal, a Group VIII noble metal, and an optional promoter metal, on a support selected from silica, alumina, silica-alumina compositions, rare earth modified alumina, and combinations thereof, doped with iron, a Group VIB metal, a Group VB metal, or a combination thereof, offers decreased reactivation time under air soak in comparison with otherwise identical catalysts. Reducing reactivation time may, in turn, reduce costs, both in inventory and capital.
