摘要： A method and apparatus are disclosed for removing water from a recycle gas stream in a catalyst regeneration process. A recycle gas stream contacts catalyst and the catalyst sorbs water from the recycle gas. Some of the now-dried recycle gas recirculates to the regeneration process, thereby decreasing the water content in the regeneration process. The catalyst containing sorbed water passes to a desorption zone, where water is desorbed from the catalyst and the desorbed water is rejected from the process. This method and apparatus are useful for extending the life of catalyst in catalytic hydrocarbon processes that employ continuous or semi-continuos catalyst regeneration zones.

摘要： A method is disclosed for recovering chlorine-containing species from the outlet gas of a hydrocarbon conversion process with a cyclic regeneration operation. The outlet gas from an off-stream catalyst bed in which regeneration is occurring is passed to another off-stream catalyst bed which contains spent catalyst and which is maintained at sorption conditions. The spent catalyst particles sorb the chlorine-containing species from the outlet gas. This method captures and retains within the hydrocarbon conversion process chlorine-containing species that would otherwise be scrubbed and lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in significant savings in operating costs of a cyclic regeneration process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst are regenerated by a cyclic regeneration operation.

摘要： A method is disclosed for decreasing the emissions of chlorine-containing species from a moving bed process for regenerating spent catalyst particles with a recycle gas stream. A recycle gas stream contacts spent catalyst particles at regeneration conditions, thereby producing a flue gas stream. The flue gas stream which contains chlorine-containing species contacts spent catalyst particles at sorption conditions. The spent catalyst particles sorb the chlorine-containing species from the flue gas stream, thereby producing the recycle gas stream. A portion of the recycle gas stream is vented from the process. This method captures and returns to the process the chlorine-containing species that would be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of the process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated in a moving bed.

摘要： A method is disclosed for recovering chlorine-containing species from an outlet stream of a zone in which the catalytic metal of a chloride-containing catalyst is reduced. The outlet stream is passed to a sorption zone which contains catalyst and which is maintained at sorption conditions. The catalyst in the sorption zone sorbs the chlorine-containing species from the outlet stream. This method captures and retains within the process the chlorine-containing species that would otherwise be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of a catalyst regeneration process that includes a reduction step. This method is adaptable to many catalytic hydrocarbon conversion processes which pass catalyst particles between or among moving bed reaction and regeneration zones.

摘要： A method is disclosed for decreasing the emissions of chlorine-containing species from a moving bed process for regenerating spent catalyst particles with a recycle gas stream. A recycle gas stream contacts spent catalyst particles at regeneration conditions, thereby producing a flue gas stream. The flue gas stream which contains chlorine-containing species contacts spent catalyst particles at sorption conditions. The sorption conditions are characterized by the substantial absence of carbon combustion. The spent catalyst particles sorb the chlorine-containing species from the flue gas stream, thereby producing the recycle gas stream. A portion of the recycle gas stream is vented from the process. This method captures and returns to the process the chlorine-containing species that would be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of the process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated in a moving bed.

摘要： A method is disclosed for decreasing the emissions of chlorine-containing species from a process for contacting catalyst particles with a recycle stream containing chlorine-containing species. Prior to contacting the catalyst particles with the recycle gas, an effluent stream that contains chlorine-containing species contacts the catalyst particles at sorption conditions. The catalyst particles sorb the chlorine-containing species from the effluent stream. This method captures and returns to the process the chlorine-containing species that would be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of the process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

摘要： A method of catalyst manufacture. A calcined tin-containing refractory inorganic oxide support or carrier material is impregnated with an acidic solution of a precursor compound of a platinum group metal and a precursor compound of an iron group metal. The impregnated carrier material is dried over an extended period to reduce the volatile content thereof to less than about 15 wt. % prior to high temperature calcination. Drying the impregnated carrier material in accordance with the present invention provides a catalyst substantially improved in activity stability.
