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  - Within the life cycle assessment, exergy analysis is one of the specific approaches to evaluate impacts on the environment through the quality of energy which is degraded during the production process [1]. Exergy can be described as a measure of resources depletion and it can be used to evaluate the process efficiency. Comparative assessment of product and processes through life cycle assessment is often used to identify the differences and environmental hotspots. This research applies exergy life cycle assessment to compare different Ni-based catalysts synthesis processes. In previous research [2,3] the authors compared novel Ni-Pd/Al2O3 catalyst synthesis processes with other ones from environmental and performance point of view. Idea of this research is to calculate the impacts on the environment by the total exergy consumption of Ni-based catalyst processes and to compare these results with the results from previous research. Compared with other Ni-based catalyst synthesis processes, the assessment results confirm the previous findings that the novel Ni-Pd/Al2O3 catalyst synthesis process has the smallest environmental impact. Furthermore, exergy life cycle assessment provided insight into impacts on the non-renewable and renewable resources.

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  - In the presented research, Ni-based catalysts were synthesized. Reticulated α-Al2O3 based foams were impregnated with ultrasonically aerosolized NiCl2 and NiCl2-PdCl2 aqueous solutions, dried at 473 K for 1 h and then reduced by hydrogen at 533 and 633 K for 90 min. Ni loading was 5 wt.%. Modified catalyst contained 0.1 wt.% of added Pd. Reduction of Ni-Pd/Al2O3 sample was almost completed at 533 K. The calcination step was avoided and lower reduction temperature was utilized. Proposed method enables formation of submicron-sized metallic particles and offers a possibility of economical and technological benefits in the catalysts production process.

AB  - Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes;
however, they quickly deactivate due to deposits formation during exploitation and sintering at elevated temperatures. Considering
that catalysts with several catalytic components possess enhanced catalytic properties, in present study the influence of temperature,
time and additives (PdCl2, FeCl2 and CuCl2) on the reduction degree of nickel(II)-chloride by hydrogen have been investigated. The
objectives of the study were selection of an appropriate catalytic activity modifier and development of a new synthesis method for
nanocomposite catalysts production, which are characterized by enhanced properties compared to the commercial Ni/Al2O3
catalysts. Obtained experimental results clearly indicate that the best effect was achieved with addition of 0.1 wt. % PdCl2, whereby
NiCl2 reduction degree was 58.16% at 653 K and Pd significantly increased the reduction rate. According to the obtained results,
new technological synthesis method of nanocomposite Ni-Pd/Al2O3 catalysts was proposed, where Ni and Pd, as catalytically active
components, are homogeneously dispersed in monolithic Al2O3 based ceramic foam.
