摘要： A semi-continuous process for combusting coke from catalyst particles in a fixed bed is improved by injecting combustion air for the regeneration section to the three places, upper air to the burn zone, middle air to the chlorination zone and lower air to the burn zone. By this method combustion gas is added the halogenation gas loop which circulates chlorination gas around the chlorination zone in substantially closed system. Any gas that leaves the chlorination zone flows into the burn zone from the chlorination zone. Thus, passing additional air to the chlorination zone increases the oxygen concentration of the chloriation gas to that additional oxygen-containing chlorination gas and chlorination gas with a higher oxygen concentration passes into the burn zone from the chlorination zone. This method adds air for coke combustion and improves platinum dispersion in the halogenation zone.

摘要： A vessel for effecting multiple treatment steps needed to regenerate spent hydrocarbon conversion catalyst. Regeneration is accomplished in a moving bed of catalyst, where catalyst is passed through several treatment zones in the regeneration vessel. Catalyst is contacted with a hot oxygen-containing gas stream in order to remove coke which accumulates on the catalyst while it is in a hydrocarbon conversion zone. After the coke is burned off in a combustion zone, catalyst is passed into a drying zone for removal of water formed in the combustion zone which has remained on the catalyst instead of being carried off with combustion gases. Water removal is accomplished by passing a hot dry air stream through the catalyst. This air stream is introduced into the bottom of the regeneration vessel and is heated by exchange of heat with catalyst, thereby effecting the required cooling of the catalyst. Before passing into the drying zone, the air is heated further by heating element located in the vessel. After passing through the drying zone, the air stream provides oxygen for combustion in the combustion zone.

摘要： A process for the regeneration and reactivation of coked iridium-containing catalysts, and chemical modification and passivation of iron scale carried over from a ferrous metal regeneration circuit to the catalyst-containing reactor, or reactors, to suppress reaction between the iron scale and catalyst as normally occurs when iron scale contacts the catalyst of a reactor, or reactors. The iron scale is rendered non-reactive or inert in the reactor environment by converting the iron scale to a passive form, preferably ferric oxide, by employing ab initio an extended low temperature primary burn while purging the system of carbon oxides, notably carbon monoxide and carbon dioxide. Thereafter, the agglomerated metal, or metals, component of the catalyst is redispersed at conditions insufficient to reduce the oxidized iron scale which is contained in admixture with the regenerated catalyst. The agglomerated metal, or metals, component of the regenerated catalyst contained in admixture with the passivated iron scale is redispersed in a non-reducing atmosphere to return the catalyst to its active state without reduction of the passivated iron scale. This process is an improvement in those described in U.S. Pat. No. 4,514,284 and U.S. Pat. No. 4,517,076, respectively.

摘要： A process is described for rejuvenation of a deactivated highly siliceous noble metal-containing zeolite catalyst which contains agglomerated noble metals. The process comprises initially reducing the deactivated catalyst in hydrogen, pretreating the thus reduced catalyst with an inert gas stream containing about 0.001 to 10 weight percent hydrogen chloride, redispersing the noble metal with an inert gas stream containing about 0.001 to 10 weight percent Cl in the form of Cl.sub.2 or Cl-containing organic material, and subsequently reducing the catalyst. The Cl-treatments may optionally occur in the presence of oxygen or sources of oxygen.

摘要： A continuous method for regenerating deactivated catalyst particles in a regeneration zone through which the particles are downwardly movable by way of gravity-flow. Particles are initially introduced into an upper carbon-burning/halogenation zone wherein they are contacted, in a first section, with a first air stream and a first mixture of steam and a halogen, or halogen-containing compound. Partially regenerated/reconditioned particles are then contacted, in a lower second section, with a second air stream and second mixture of steam and halogen. From this two-sectioned, carbon-burning/halogenation zone, the catalyst particles flow via gravity into a drying zone wherein they are contacted by a substantially dry air stream.

摘要： A deactivated hydrocarbon conversion catalyst, which is a combination of catalytically effective amounts of a platinum group component, a tin component and a halogen component with a porous carrier material, which is free of labile sulfur and which has been deactivated by a deposition of carbonaceous material thereon during a previous contacting with a hydrocarbon charge stock at hydrocarbon conversion conditions, is regenerated by the sequential steps of: (1) burning carbon from the deactivated catalyst at a relatively low temperature with a substantially sulfur-free first gaseous mixture containing relatively small amounts of oxygen, H2O and HCl; (2) treating the resulting catalyst at a relatively high temperature with a second gaseous mixture containing O2, H2O and HCl; (3) purging oxygen from contact with the resulting catalyst; and (4) reducing the resulting catalyst by contacting with a substantially sulfur-free third gaseous mixture containing hydrogen and small amounts of H2O and HCl. Key features of the regeneration method involve: the presence of both H2O and HCl in the gaseous mixtures used in the carbon-burning, oxygen-treating and reduction steps; the use of sulfur-free gaseous mixtures in all of these steps; and the careful control of the mole ratio of H2O to HCl employed in each of these gaseous mixtures.
