Recycling of platinum group metals from the used auto catalytic converters is profitable from ecological and also economical point of view. This work presents the analysis of the chances of removing the platinum group metals (PGM) from the used auto catalytic converters applying pyrometallurgical and hydrometallurgical methods. The characteristics of auto catalytic converter is shown as well the available technologies used for processing the auto catalytic converters are also presented.

    • "The recycling process decreases catalyst waste in the environment and prevents environmental pollution (Hagelüken, 2012; Nowottny et al., 1997). Among the PGMs, Pd is the most widely used in the automobile industry as a catalyst and is ~2 times cheaper than Pt and Rh (Saternus and Fornalczyk, 2013; Yang, 2009). In recent years, hydro-and pyrometallurgical processes have been employed to recover metal ions from the waste catalyst (Fornalczyk, 2012; Saternus and Fornalczyk, 2013). "

    ABSTRACT: The extraction of Pd(II) ions from automotive catalyst residue solutions in Cl− media was studied using 5,11,17,23,29,35-tert-butyl-37,38,39,40,41,42-(dimethylthiocarbamoyl)oxy thiacalix[6]arene (1) and 5,11,17,23-tert-butyl-25,26,27,28-(dimethylthiocarbamoyl)oxy thiacalix[4]arene (2). Compounds 1 and 2 were found to have higher Pd(II)-ion extraction abilities than p-tert-butylthiacalix[6]arene (3) and p-tert-butylthiacalix[4]arene (4) in Cl− media. The prepared compounds selectively extracted Pd(II) ions from the single-metal, simulated mixed-metal, and automotive catalyst leached solutions. Compound 1 extracts 99.5–82% of Pd(II) from 0.1–2.0 M HCl media and 75–55% from 4.0–8.0 M HCl media. Compounds 1 and 2 have very high Pd(II)-loading capacities, which depend on the number of dimethylthiocarbamoyl moieties in 1 and 2. Pd(II) extraction efficiency of 1 and 2 was dependent on the Cl− concentration and independent of the H+ concentration. The acid durability test of the extractants was carried out with 2.0 M HCl–1.0 M HNO3 solutions. The FT-IR results showed that compounds 1 and 2 are more durable than compounds 3 and 4 in acidic media and are suitable for metal extraction in highly acidic media. In addition, compounds 1 and 2 selectively extracted 99% of Pd(II) ions from an automotive catalyst residue leached solution composed of Rh, Pd, Pt, Zr, Ce, Ba, Al, La, and Y in 1.0 M Cl− media. Thus, 1 and 2 can be used as effective extractants for Pd(II) separation from secondary resources.

    ABSTRACT: A deterministic expansion model for sizing of N satellite links in mobile networks during exploitation is being developed. The model is applied to short- or medium-term planning with finite number of discrete time periods. In the planning process it can help the Land Earth Station Operator (LESO) to find the optimal capacity-expansion policy for new constructions and conversions of channel equipment that minimizes the total cost. The model for the capacity expansion problem with shortages (CEPS) allows capacity conversions from one satellite link to another in both directions, but limitations can be imposed. Furthermore, upper bounds on shortages and idle capacities can be imposed. The traffic demand increments for additional capacity in any time period and for any link can be negative. All cost functions are assumed to be piecewise concave and non-decreasing away from zero. Using a network flow approach the paper develops an efficient dynamic-programming algorithm to minimize the total expansion cost. An heuristic algorithm is tested on many examples, and its efficiency is compared with an algorithm based on an exact approach

    ABSTRACT: A new approach towards monuments, considering them as a passive sampler of pollution, is presented. Cultural Heritage objects suffer daily the damages of environmental pollution, especially in those areas interested by heavy traffic. Since monuments undergo only periodic conservation or maintenance works, surfaces are able to accumulate atmospheric deposit and to record changes in its composition. An optimised analytical protocol was developed in order to quantify platinum and rhodium at trace level on surfaces. The two elements have become tracers of automobile emissions in recent years, since the introduction of catalytic converters, and could have catalytic effects on the decay reactions of natural and artificial stone materials. As a first case study, the cement mortar surfaces of a twentieth century monument, the Camerlata Fountain, in Como (Italy) were investigated. The surfaces of the monument were scraped in areas both exposed to atmosphere and sheltered by the architectural elements of the building. The powders were dissolved by microwave-assisted mineralisation with a solution of HCl and HNO(3). The solution was filtered, irradiated and analysed by adsorptive cathodic stripping voltammetry. The powders were also analysed by infrared spectroscopy and X-ray diffraction in order to determine the chemical and mineralogical composition. An analysis protocol was set up considering the matrix effect and the expected low concentrations of the two metals. The results enlightened variable concentration values and distribution areas of platinum (0.013-45 μg/kg) and rhodium (0.55-274.4 μg/kg), suggesting the ability of artificial stone surfaces to accumulate the two elements. The sample chemical and mineralogical composition was consistent with a typical cement plaster interested by decay phenomena. This work investigated the relation between Cultural Heritage and pollution by another point of view. The analytical protocol presented in this paper was effective in determining platinum and rhodium in traces on the investigated stone surfaces with negligible matrix effects. The presence of platinum and rhodium on monument surfaces should be of significant interest when planning Cultural Heritage conservation. A better knowledge of the role of the two metals in decay phenomena could impact in a positive way artwork conservation.
