“…Thus, the use of these pyrolysis oils for energy purposes, either in their natural form or transformed by fractional distillation into fuels, cannot be ignored. The HHV recorded for the SSPyOil, obtained with a heating rate of 10ºC/min, namely 8126 kcal/kg, was similar to the values presented in literature [1,11,12,35,36] and in some cases being even double [11,33]. In contrast, the concentration of N and S, two elements with high potential for negative environmental impact, through the formation of gaseous oxides, such as SOx and NOx, after the oils combustion, were higher than the data reported in literature, namely, for N it was obtained 6.00 wt% in this study in comparison with 1.50 -5.60 wt% [33,37] and for S it was obtained 1.20 wt% in this study in comparison with 0.43 -0.50 wt% [33,34].…”

“…Comparing the HHV of oils obtained in this work with the data reported in literature of conventional liquid fuels [35], such as gasoline, kerosene, diesel and heavy fuel oil (Table 5), it can be observed that are similar. The investigation of metals content in SS is very important, therefore Table 6 reveals the metal concentrations found in pyrolysis oils, but also in different types of liquid fuels from various studies [35,38].

“…Thus, the obtained products were introduced in polypropylene capsules and centrifuged at 5000 rpm/min, the solutions being separated into three fractions, namely ~ 15 wt% aqueous, ~ 83 wt% viscous https://doi.org/10.37358/RC.20.10.8361 and ~ 2 wt% solid particles (tar). Tables 3 and 4 summarize the elemental compositions and the energy values of the oils resulted in this study against the values of various oils from different studies [1,11,12,[33][34][35]. Higher HHVs were obtained for the oils resulted from pyrolysis processes which were performed at heating rates of 5°C/min and 10°C/min.…”

The study aims to promote clean energy technologies that ensure the recycling and recovery of waste, namely the sewage sludge (SS), by converting it into products (e.g. oil, gas) with added value, contributing thus to reducing the negative impact on environment and health. An experimental setup was proposed in order to achieve the pyrolysis process, by varying the heating rate, (5�C/min, 10�C/min and 50�C/min). The resulted products, namely i) char - SSPyChar, ii) oil - SSPyOil and iii) gas - SSPyGas, were investigated in terms of elemental content, high heat value (HHV), low heat value (LHV) and emission factor (EF). The pyrolysis oils obtained with lower heating rate, 5�C/min and 10 �C/min, presented higher HHV, in comparison with the oils obtained at 50 �C/min, which were rich in water. These oils can have a negative impact on the environment, through their combustion due to their high content of N (6 wt%) and S (1.2 wt%), responsible for the formation of NOx and SOx. Pyrolysis gas revealed in its composition high contents of hydrocarbons (C1-C6), carbon dioxide (CO2) and hydrogen (H2). The highest HHV was obtained by using 5�C/min increment, namely 33.81 MJ/m3. Also, the pyrolysis gases had comparable energy values with natural gas, biogas or gases resulted from the plastic pyrolysis.

“…Compositional characterization of the oils obtained in the pyrolysis processes was achieved using an elemental analyser, Flash EA 2000 (Thermo Scientific, UK). PPO samples were introduced into special tungsten -silver nacelles, subjected to combustion-pyrolysis at extremely high temperatures of 950 °C -1050 °C; the resulting gases (CO2, NO2, SO2, H2O, CO) passed a quartz reactor with a special filler, then the gas chromatographic columns with SM5A -Porapak Q filler, and detected by a thermal conductivity detector -TCD [24]. Calibration of the elemental analyser was performed with 2.0-3.0 mg of BBOT (C: 72.58 wt.%, H: 6.09 wt.%, S: 7.43 wt.%, O: 7.41 wt.% and N: 6.54 wt.%), an amino acid traceable to NIST.…”

The increased demand for energy sources is the driving force to convert organic compounds into alternative fuels. Plastic waste disposal affects the environment, since they are not easily recycled and, during the recycling process, they can produce waste ash, heavy metals, or potentially harmful gas emissions. In the plant design for plastic converting into fuel, the chemical reactor is one of the advanced equipment in the field of chemical and process engineering. This study emphasizes the feasibility of pyrolysis process for valorisation plastics by producing energy-efficient products. In this respect, samples of polypropylene, polyethylene and polystyrene were used as models and subjected to pyrolysis processes at 450 �C, in the presence of two types of mesoporous silica materials, MCM-41 and SBA-15, using a modern developed reactor. The use of mesoporous materials increased the calorific value of the obtained oil and gas, thus improving the economic potential of the process end products. This study dealt with the extraction of oil from plastics termed as plastic pyrolysis oil (PPO) and plastics pyrolysis gas (PPG), with a composition rich in different types of hydrocarbons and they can be marketed at much cheaper rates compared to that present in the market.

“…Some authors propose new approaches and energy solutions for the power supply of EV-CS, by integrating new technologies for electricity production, especially hydrogen energy. [36][37][38][39][40] Xu et al 39 introduce a unique concept to provide, in the same location, both the electric charging of the electric vehicles and the hydrogen supply of fuel cell vehicles. Mehrjerdi conducts a study on the optimal cooperation of solar panels, hydrogen storage system, water electrolyzer, fuel cells, and diesel generator with the goal of fuelling at the same time electric vehicles and hydrogen vehicles.…”

The Electric Vehicle (EV) as a clean alternative to Classic Vehicle that use fossil fuels is promoted as an immediate solution to improve the quality parameters of the environment related to the transport sector. The transition to clean electrified mobility must be considered from the sustainability spectrum, and the planning of a strategy related to the implementation of electric vehicles implies, from the beginning, providing clean energy conditions to go toward a green-to-green paradigm. It should be noted that the successful implementation of the "green electro mobility" concept depends heavily on the green energy supply solutions of green electric vehicle, so Electric Vehicle Charging Stations (EV-CS) should be powered by electricity generation systems based on green resources. This research article has as main objective the environmental impact assessment from the perspective of CO 2 emissions embedded in green stand-alone energy systems and the estimation of the environmental benefits of their implementation in the power supply of EV-CS from the perspective of avoided CO 2 emissions compared to the classic electricity supply grid. The results indicate that the green energy systems represent feasible solutions for the independent energy support of electric vehicle charging stations, being able to supply electricity based on on-site available 100% alternative energy sources. Related to 1 kWh of electricity, the CO 2 emissions embedded in these systems represent on average 11.40% of the CO 2 emissions of the electricity supplied through the grid at European level and on average 7.10% of the CO 2 emissions of the electricity supplied through the grid worldwide. Results also show that the average price of 1kWh of electricity generated by the analyzed systems is 4.3 times higher than the average unit price of the European Union grid energy, but this indicator must be correlated with the kgCO 2 /kWh cost savings compared to the electricity production from classic power plants.
