Definitions

  • the present invention relates generally to the field of platinum metallurgy. More specifically, the present invention relates to a process for the recovery of platinum group metals from scrap metal material, particularly from automobile catalytic converters, which contain platinoids in the form of double or triple complexes (Pt/Rh, Rd/Rh, Pt/Pd/Rh), applied on honeycomb-like blocks of cordierite.
  • the present invention also relates to a reactor for carrying out said process.
  • certain catalysts may include one or more catalytically active metals, and particularly metals of the platinum series.
  • the rejects from the fabrication of such catalyst, as well as the used catalyst needs to be treated in order to recover therefrom at least the precious metals, in a manner that is as complete and cost-effective as possible.
  • U.S. 4,077,800 to Peka et al. relates to a method for the recovery of platinum from a spent catalyst involving subjecting the catalyst to fluorination with elementary fluorine or a mixture thereof with hydrogen fluoride at a temperature ranging from 100°C to 600°C. The resultant fluoride is then converted to platinum in elemental form.
  • U.S. 4069040 to Thomas et al. relates to a method for recovery of platinum and iridium from catalysts.
  • the recovery is accomplished by a solubilization of the catalysts by means of hydrochloric acid and by extraction, for example by ion exchange resins.
  • the process of the present invention allows for a high percentage of recovery of platinoids (platinum group metals) into solution, requiring a relatively small amount of reagent, when compared to analogous methods of the prior art.
  • the present invention relates to a process for recovering platinum group metals from a waste catalyst such as a honeycomb shaped or pelletized support formed from cordierite or another material containing catalytic metals.
  • the process of the present invention employs a lixiviation process which differs from those of the prior art in that the concentration of oxidized metals in the solution is continuously increased through the use of acid mixtures both in the liquid and in the vaporized state for achieving platinoid oxidation.
  • the transition to the gaseous state eliminates the problem of inadequate contact between the metals and the oxidative substance resulting from diffusion and ensures full transfer of the platinoids to solution, thus obviating the need for so many repeated cycles.
  • the catalyst blocks are placed in the reactor in a container having a perforated bottom.
  • the blocks are sprayed with an acidic (preferably hydrochloric acid) solution, which acts as a complex forming and impregnation agent.
  • the amount of acid is carefully controlled such that the catalyst is kept above the level of the liquid.
  • the present invention relates to a process for recovering platinum group metals from a spent catalytic member comprising introducing a spent catalytic member into a reaction chamber, wetting the spent catalytic member with an acidic solution, heating the reaction chamber and adding an oxidizing agent. The heating is allowed to continue such that vapors of the oxidizing reagent are produced and recycled through the reaction chamber such that condensate formed from said vapors contain platinum group metals released from the catalytic member. The platinum group metals are subsequently recovered from the collected condensate.
  • the reactor is heated and the reagent liquid is added. This process takes a certain amount of time, during which the oxidizing vapor is repeatedly circulated in the channels and pores of the catalyst through which the condensate is subsequently released.
  • the blocks thus act as a condenser until thermal equilibrium is achieved.
  • the resultant solution is transferred and filtered.
  • the catalyst is washed thoroughly and the wash water is combined with the solution.
  • the platinoids and rare-earth cerium, which is also in the solution, can then be recovered from the solution using known methods.
  • the method of the present invention is universal since it not only allows for treatment of block catalysts having any combination of noble metals, but also enables the recovery of cerium, which is sometimes included in order to reduce the thermal coefficient of expansion.
  • the controlled introduction of measured quantities of highly aggressive oxidizing agent helps to reduce the load on the cleaning devices.
  • the present invention relates to a process for recovering platinum group metals from a spent catalytic member comprising;
  • the spent catalytic member is an automobile catalytic converter.
  • the acidic solution is a hydrochloric acid solution.
  • the process also comprises placing the catalytic member onto a surface having perforations.
  • Said surface is preferably the bottom of a reaction container. Alternately, said surface may be a platform that is mounted at a predetermined height in the reaction chamber. It is appreciated that the surface serves to hold the catalytic member while also allowing vapors from the solution below to rise through said surface (via the perforations) to contact the catalytic member and, subsequently, for droplets (condensate from the vapors) to return to the solution.
  • the acid solution is added in an amount corresponding to approximately 25% by weight of the catalyst.
  • the process further comprises recovering platinum groups metals from the solution obtained in step (e). This may be accomplished through any appropriate means known in the art.
  • the catalytic member is washed with water and the wash water is combined with said solution prior to final recovery of the platinum group metals.
  • the oxidizing agent is a nitric acid.
  • the process also comprises pre-treating the catalytic member with aqua regia.
  • the process further comprises pre-roasting the catalytic member.
  • the present invention also relates to a reactor for carrying out the process as defined above.
  • the present invention further relates to a reactor for recovering platinum group metals from a spent catalytic member comprising;
  • reaction chamber for receiving a spent catalytic member, said reaction chamber and having an inlet for introducing a solution into the reaction chamber and an outlet for withdrawing the solution from the chamber;
  • the reactor parts are formed form titanium metal.
  • the spent catalytic member is positioned in the reaction chamber inside of a reaction container, said container having a perforated bottom portion such that vapors from the solution penetrate through the perforated bottom portion.
  • Figure 1 represents a cross-sectional schematic view of a reactor for recovering platinoids from a spent catalyst, according to preferred embodiments of the present invention.
  • a reactor will now be described that is adapted for carrying out the process of the present invention.
  • the reactor of the present invention comprises a reaction chamber (5), having an inlet (9) and an outlet (3) for the entry and exit, respectively, of fluids.
  • a spent catalyst (11) is preferably positioned in the chamber (5) inside a container (10) having a perforated bottom (7).
  • the catalyst (11) may be, for example, an automobile catalytic converter.
  • the perforated bottom (7) preferably has about 30-50 holes per centimeter squared.
  • the reaction chamber (5) is disposed inside of a heating chamber (4) that is filled, for example, with oil (8).
  • the oil (8) is heated via electric heaters (12a) (12b). When the oil is heated, this causes an acid solution (6) in the reaction chamber (5) to heat.
  • Other appropriate heating means could also be employed for heating the reaction chamber (5).
  • the reactor further comprises a condenser (2), located at the top portion of the reaction chamber (5), through which water (1) is conveyed, such that vapors rising to the top of the chamber (5) and contacting the condenser (2) condense into droplets.
  • Some preferred embodiments further include a propeller (not shown) situated beneath the condenser (2) and above the container (11) that facilitates conveying of the condensate to the bottom of the reaction chamber (5) (back to the solution).
  • the catalyst (10) is wetted with a predetermined amount of an acid solution and is placed inside the container (11) in the reaction chamber (5).
  • part of the remaining acid solution is introduced into the reaction chamber (5) via inlet (9) so as to occupy the lower most section of the chamber (5) (below the container).
  • the oil (8) in the heating chamber (4) is then heated so as to cause the temperature in the reaction chamber (5) to increase.
  • an oxidizing agent is introduced also via inlet (9).
  • the heating is continued such that vapors from the solution (6) in the lower part of the chamber (5) rise up through the holes in the perforated bottom (7) of the container (11), and circulate throughout said chamber (5), through the openings in the catalyst (10) (the temperature is held such that the liquid continuously produces vapors; this may correspond to any appropriate temperature range depending on other reaction parameters), "collecting" platinum group metals from the catalyst.
  • Both the catalyst (10) and the condenser (2) act to cause the vapors to re-condense into liquid droplets into which the platinoids from the catalyst (10) are dissolved.
  • the droplets fall to the bottom of the chamber (5), they again vaporize due to the heat and are caused to circulate again through the reaction chamber (5).
  • the solution (6) at the bottom of the chamber (5) has an continuously increasing amount of platinum group metals dissolved therein.
  • the solution is preferably withdrawn through outlet (3) and the platinoids are recovered from the solution through conventional methods known in the art.
  • a 1.2kg catalytic converter from a Mercedes Benz was found to have a residual mass content of 0.12% and 0.008%, respectively, of platinum-rhodium catalyst. Because the percentage of catalyst was small, and did not exceed 2.2%, no preliminary roasting was performed.
  • the catalyst was placed in a fluoroplastic receptacle (of a reactor) and wetted with 260ml of HCl (1:1) solution (25% of the initial catalyst mass). Then the rest of the HCl in the amount of 70ml was added to the reactor. The reactor was then heated such that the solution was brought to a boil, and 60ml of concentrated HNO 3 and by parts 150ml of 30% hydrogen peroxide solution were successively introduced. The lixiviation process was run for 1.5 hours.
  • a palladium-rhodium catalytic converter from a Volvo was found to have 0.08% palladium and 0.006% rhodium by mass. There was also a deposit of pyrocarbon in the amount of 8.7% by mass.
  • the catalyst was initially roasted for 45 minutes at 540°C. After cooling, it was placed in a fluoroplastic receptacle and treated with a dilute HCl solution (HCl: water in a 1:5 ratio) mixed with hydrogen peroxide at a ratio of 1:4 by volume (the total amount added was 460ml). The lixiviation process was then continued as in Example 1 and the recovery yield was 97.8% for palladium and 92.4% for rhodium.
  • a deactivated catalytic converter from a Nissan was found to contain 0.04% platinum, 0.06% palladium, 0.007% rhodium, and 1.4% cerium. It was treated with dilute aqua regia followed by the immersion in HCl as in Example 1. The lixiviation process was carried out as in Example 1. The recovery yield was 98% for platinum (0.3878g), 98.2% for palladium (0.5831g), and 94.1% for rhodium (0.0653g).
