Abstract

LA PRESENTE DIVULGACIÓN SE REFIERE A LA RECUPERACIÓN DE MGP (METALES DEL GRUPO PLATINO) A PARTIR DE CATALIZADORES<br /> HOMOGÉNEOS CONSUMIDOS PRESENTES EN UNA FASE ORGÁNICA.<br /> ESPECIFICAMENTE, SE PROPORCIONA UN PROCESO PIROMETALÚRGICO POR EL CUAL LOS MGP, Y EL RH EN PARTICULAR, SE CONCENTRAN EN FASES METALÚRGICAS, VOLVIÉNDOLOS ACCESIBLES PARA SU REFINACIÓN DE ACUERDO CON PROCESOS CONOCIDOS.<br /> ATAL EFECTO, SE DIVULGA UN PROCESO QUE COMPRENDE LOS SIGUIENTES PASOS:<br /> - PROPORCIONAR UN HORNO CON BAÑO DE FUNDICIÓN, QUE CONTIENE UN INYECTOR SUMERGIDO EQUIPADO PARA ENCENDER<br /> COMBUSTIBLE LIQUIDO;<br /> - PROPORCIONAR UN BAÑO DE FUNDICIÓN QUE COMPRENDE UNA FASE METÁLICA Y/O DE MATA Y UNA FASE DE ESCORIA;<br /> - ALIMENTAR A TRAVÉS DEL INYECTOR EL CATALIZADOR HOMOGÉNEO GASTADO Y UN GAS QUE CONTIENE 02, RECUPERÁNDOSE LA<br /> MAYOR PARTE DE LOS MGP EN LA FASE METÁLICA Y/O DE MATA;<br /> - SEPARAR LA FASE METÁLICA Y/O DE MATA QUE CONTIENE LOS MGP DE LA FASE DE ESCORIA.<br /> LA ENERGIA ALMACENADA DEL RESIDUO ORGÁNICO PUEDE UTILIZARSE EFICAZMENTE PARA CALENTAMIENTO Y/O REDUCCIÓN DE LA CARGA METALÚRGICA EN EL HORNO. SE RECUPERAN LOS METALES VALIOSOS CON ALTO RENDIMIENTO, Y SE DESTRUYE EL RESIDUO ORGÁNICO PERJUDICIAL DESDE EL PUNTO DE VISTA AMBIENTAL.<br />  THIS DISCLOSURE REFERS TO THE RECOVERY OF MGP (METALS OF THE PLATINUM GROUP) FROM CATALYSTS CONSUMED <br /> HOMOGENOUSLY PRESENT IN AN ORGANIC PHASE. <br /> SPECIFICALLY, A PYROMETALURGICAL PROCESS IS PROVIDED BY THE MGP THE RH IN PARTICULAR, ARE CONCENTRATED ON METALLURGIC PHASES, MAKING THEM ACCESSIBLE FOR REFINING ACCORDING TO KNOWN PROCESSES. <br /> ATAL EFFECT, A PROCESS THAT INCLUDES THE FOLLOWING STEPS IS DISCLOSED: <br /> NO BATHROOM WITH PROPORTION FOUNDRY, CONTAINING A SUBMERGED INJECTOR EQUIPPED TO IGNITE <br /> LIQUID FUEL; <br /> - PROVIDE A FOUNDRY BATH THAT INCLUDES A METALLIC AND / OR MATT PHASE AND A SLAG PHASE; <br /> - FEED TO THROUGH THE INJECTOR THE SPENT HOMOGENOUS CATALYST AND A GAS CONTAINING 02, RECOVERING THE <br /> MOST OF THE MGP IN THE METALLIC AND / OR MATA PHASE; <br /> - SEPARATE THE METALLIC AND / OR MATA PHASE THAT IT CONTAINS THE SLAUGH PHASE MGP. <br /> THE IN ERGIA STORED FROM ORGANIC WASTE CAN BE USED EFFECTIVELY FOR HEATING AND / OR REDUCING THE METALLURGICAL LOAD IN THE FURNACE. VALUABLE METALS ARE RECOVERED WITH HIGH PERFORMANCE, AND HARMFUL ORGANIC RESIDUE IS DESTROYED FROM THE ENVIRONMENTAL POINT OF VIEW. <br />
