AB  - This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical synthesis routes. It had a reduced number of process stages and a lower environmental impact at the same time. In order to examine the phase composition of the catalyst after sintering at 800 °C, the XRD analysis was carried out. The catalyst was then tested in chlorodifluoromethane dehalogenation process on laboratory scale at temperatures of 300, 400 and 500 °C in the presence of water vapor. Catalyst achieves high dehalogenation efficiencies of 88.6, 95.9, and 99.5 % for each of the process temperatures, respectively. Obtained results are in the range with those achieved by using thermo-chemically prepared dehalogenation catalysts.

AB  - The objects of this investigation were the comparative kinetic analysis of the NiO and NiCl2 reduction by hydrogen during an induction period and elimination of the calcination during the synthesis of Ni/Al2O3 catalysts.The effect of temperature and time on NiO and NiCl2 reduction degrees was studied. Avrami I equation was selected as the most favorable kinetic model and
used to determine activation energy of the NiO and NiCl2 reduction for the investigated temperature range (623–923 K) and time intervals (1–5 minutes).Theinvestigation enabled reaching conclusions about the reaction ability and rate of the reduction processes.
Afterward,Ni/Al2O3 catalystswere obtained by using oxide and chloride precursor forNi.The catalystswere supported on aluminabased foamand prepared via aerosol route. Properties of the samples before and after low-temperature hydrogen reduction (633K) were compared.Obtained results indicated that the synthesis ofNi/Al2O3 catalysts can be more efficient if chloride precursor for Ni is directly reduced by hydrogen during the synthesis process, without the calcination step. In addition, Ni-Pd/Al2O3 catalysts with different metal content were prepared by using chloride precursors. Lower reduction temperature was utilized and the chlorides were almost completely reduced at 533 K.

AB  - This paper presents investigation of possibility for electric arc furnace dust (EAFD) and electronic waste (e-waste) valorization trough stabilization process, in order to achieve concurrent management of these two serious ecological problems. EAFD is an ineviTab. waste material coming from the electric arc furnace steel production process, classified as a hazardous waste. Furthermore, it is well known that residual materials generated in the e-waste recycling process, like LCD (Liquid crystal displays) waste glass, are not suiTab. for landfill or incineration. In this study, these two materials were used for investigation of possibility for their valorization in ceramic industry. Thus, an innovative synergy of waste streams from metallurgical and e-waste recycling industry is presented. Investigation included a complex characterization of raw materials and their mixtures, using chemical methods, optical microscopy, scanning electron microscopy, as well as methods for determining the physical and mechanical properties. Based on these results, it was found that material suiTab. for use in ceramics industry as a partial substituent of quartzite and fluxing components can be produced. Besides solving the environmental problem related to EAFD and LCD disposal, by replacement of raw materials certain economic effects can be achieved.

AB  - Present paper represents a methodology for establishing a relationship between the composition of mixtures of iron-bearing non-standard dispersed raw materials for production of sinter and its most important metallurgical properties, in accordance with the appropriate phase of the production technological process. Using an appropriate software package, the database of available resources is formed. Raw data in the database include: chemical composition, bulk density, grain size distribution, moisture content and the annual quantity generated. The base is divided into basic raw materials and additives. Basic, iron-bearing, raw materials are electro-arc furnace dust (EAFD), pyrite cinder and mill scale, and additives are: flux (lime), binders (cement, bentonite) and reducer (coke). For the study of these relations the planned experiment is conducted, based on the Simplex plane. The connection between the composition of the dispersed iron-bearing mixture, as an independent variable, and dependent variables (metallurgical properties such as resistance to impingement and compression strength) was determined using correlation and regression analysis, where mathematical models for fast and reliable projected synthesis the required metallurgical properties of sinter were obtained.

AB  - The reduction of WO3 with hydrogen in a vertical tube reactor is a new approach to the reduction of tungsten oxide compared to conventional procedures in a stationary layer. The advantage of this method is the intensive contact between the reducent and the oxide particles, a higher degree and a shorter time of reduction of only a few seconds, compared to the several hours processing time in a horizontal tube reactor.
The characterization of the WO3 powder and of the tungsten powder included a SEM  microstructural examination and DT/TG analyses. The SEM examination of the tungsten powder indicates the presence of small particles with a size of about 1 μm, also within an agglomerated porous foam structure. Tungsten powder with a particle size of less than 1 μm is obtained at an optimal temperature with a suitable flow of hydrogen, as a result of stretching and the cracking of large particles, first in the reaction zone, and then, due to appropriate shock of the temperature, outside of this zone.
Using an appropriate mathematical model, the degree of reduction and the time required for the formation of tungsten particles during the hydrogen reduction of WO3 in a vertical tube reactor were determined. Experimental studies have shown that the degree of reduction of WO3 with hydrogen in a vertical tube reactor increases with the temperature and the flow of hydrogen.

AB  - Automotive batteries are a major source for secondary lead processing, followed by generation of
hazardous waste such as secondary lead slag. It has been used in presented research in a cement based
stabilization/solidification process for the manufacture of concretes. The dependence of concrete properties
with slag (10%, 20%) and additive (MgO, CaO, Ba(OH)2, CaSO4∙CaO) on the properties of concrete has been
studied by measuring the compressive strength and lead leachability by TCLP method.
Stabilization/solidification of secondary lead slag in concrete was most effective with 10% of slag as
replacement of 15% aggregate and magnesium oxide as replacement of 5% cement.

AB  - Relying exclusively on domestic raw materials and own technology, and by applying metallothermic processes (aluminothermic and silicothermic), the following ferroalloys have been obtained under semi-industrial conditions: ferrowolfram, ferroboron, ferrotitanium and ferroalloys of complex composition. The quantitative and qualitative composition of the metallothermic mixes and thermodynamic conditions of the process have been optimized for each ferroalloy. The obtained quality of ferroalloys justifies their industrial production, which can be accomplished practically without any investment.
